Subject [incubator-nuttx-apps] branch releases/9.0 updated: Remove the obsolete ChangeLog.txt file
Date Fri, 24 Apr 2020 21:07:10 GMT
This is an automated email from the ASF dual-hosted git repository.

aguettouche pushed a commit to branch releases/9.0
in repository https://gitbox.apache.org/repos/asf/incubator-nuttx-apps.git


The following commit(s) were added to refs/heads/releases/9.0 by this push:
     new fe52fd1  Remove the obsolete ChangeLog.txt file
fe52fd1 is described below

commit fe52fd1026bc8df7d02380e0e51f484b955aea85
Author: Gregory Nutt <gnutt@nuttx.org>
AuthorDate: Fri Apr 24 12:43:14 2020 -0600

    Remove the obsolete ChangeLog.txt file
    
    We do not intend to update the ChangeLog.txt file for releases past 8.2. It used to be a stepping stone between the 'git log' and the ReleaseNotes. However, it no longer serves that purpose. In fact it has no purpose at all; all of the change history is in the 'git log'. That is where people look for historical information, not in the obsolete ChangeLog.

-	  'msconn' will connect the USB mass storage device; 'msdis' will disconnect
-	  the USB storage device.
-	* apps/examples/nx*:  All NX header files moved from nuttx/include/nuttx to

-	* apps/examples/tiff:  Add a unit test for the TIFF file creation logic
-	* apps/examples/lcdrw:  Add a test to verify if you can or can or read
-	  data from an LCD correctly.
-	* apps/examples/usbterm:  A USB terminal example.. more of a USB chat or
-	  serial bridge:  Data received on local console echoed via USB serial;
-	  data received on USB serial is echoed on the local console.
-	* apps/examples/touchscreen:  Add a simple, generic test for any
-	  touschscreen driver.
-	* Makefile:  The apps/ Makefile now checks for an apps/external directory
-	  or symbolic link.  If such a directory/link exists (and has a Makefile),
-	  it will be added to the apps/ build.  This allows external directories
-	  to be included into the apps/ build by simply creating a symbolic link.

-6.11 2011-11-12 Gregory Nutt <gnutt@nuttx.org>
-
-	(No major changes from 6.10)
-
-6.12 2011-12-06 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/buttons:  The button test can now be executed as an NSH
-	  built in command.
-
-6.13 2012-12-26 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/dhcpd: May now be built as an NSH built-in application
-	  by setting CONFIG_NSH_BUILTIN_APPS.
-	* apps/netutils/dhcpd/dhcpd.c: Fix several problems using host order address
-	  where network addresses expected (and vice versa).
-	* apps/examples/nettest: May now be built as an NSH built-in application
-	  by setting CONFIG_NSH_BUILTIN_APPS.
-	* apps/examples/nettest: Correct some build issues with the nettest is
-	  built for performance evaluation.
-	* apps/examples/adc:  Add a very simple test to drive and test an ADC
-	  driver.
-	* apps/examples/pwm:  Add an NSH PWM command to drive and test a PWM
-	  driver.
-	* apps/examples/can:  Add an NSH CAN command to drive and test a CAN
-	  driver in loopback mode.
-
-6.14 2012-01-15 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/buttons/main.c:  The test needs to call up_buttoninit() to
-	  properly configure the button interrupt GPIOs.
-	* apps/examples/pwm:  Add support to test the pulse count option recently
-	  added to the PWM interface.
-
-6.15 2012-02-12 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/nshlib/nsh_serial.c and nsh_usbdev.c:  If NuttX is configured to use
-	  a USB serial console, then NSH needs to wait until the USB console is
-	  connected and available.
-	* apps/examples/composite:  Add a test of the USB composite device.
-	* apps/examples/Telnetd:  Move the tiny uIP shell example from
-	  netutils/Telnetd to examples/Telnetd.  Enhanced the Telnetd daemon so that
-	  it supports Telnetd via a TTY device driver: A new TTY device driver is
-	  created when each new Telnet connection is created.  The shell thread
-	  is started with stdin, stdout, and stderr mapped to the TTY device.
-	* netutils/Telnetd:  The old uIP Telnet demo is gone.  In its place is a new
-	  Telnet infrastructure. The new Telnet daemon creates sessions that are
-	  "wrapped" as character devices and mapped to stdin, stdout, and stderr.
-	  Now the Telnet session can be inherited by spawned tasks.
-	* examples/Telnetd:  Add a test for the new Telnet daemon.
-	* examples/Telnetd/telnetd_driver.c: Move the internal socket structure from
-	  the daemon's socket array into the driver's state data so that it will be
-	  independent from the Telnetd daemon.
-	* apps/system/readline:  Moved the old nuttx/lib/stdio/lib_fgets.c here
-	  and renamed it as readline().  The old fgets was simplied and the overloaded
-	  readline functionality was removed.
-	* apps/netutils/ftpd:  Add an FTPD server (does not even compile on initial
-	  checkin).
-	* apps/examples/ftpd:  Add a test for the FTPD server (untest on initial
-	  check-in).
-	* apps/nshlib/nsh_fscmds.c:  Add support for a 'dmesg' command that will
-	  dump the system log if CONFIG_SYSLOG is selected.
-
-6.16 2012-03-10 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/qencoder:  Add a quadrature driver test.
-	* apps/examples/ostest/fpu.c:  Add a test to verify that FPU registers
-	  are properly saved and restored on context switches.
-	* apps/system/readline/readline.c:  readline() will now treat either a
-	  backspace or a DEL character as a backspace (i.e., deleting the character
-	  to the left of the cursor).  This makes NSH less dependent on particular
-	  keyboard mappings of the Backspace key.  Submitted by Mike Smith.
-	* apps/system/cdcacm:  An example that illustrates how the CDC/ACM driver
-	  may to connected and disconnected through software control.
-	* apps/examples/nsh/nsh_main.c:  If available, call up_cxxinitialize() to
-	  initialize all statically defined C++ classes.
-	* apps/nshlib:  Now supports a USB serial device for NSH console I/O.  This
-	  allows NSH to be used on boards that have USB but no serial connectors.
-
-6.17 2012-04-14 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/can:  Add conditional compilation so that the test can be
-	  configured to only send messages or to only receive messages.  This will
-	  let the test work in other modes than simple loopback testing.
-	* apps/examples/hello and apps/examples/ostest:  Can now be built as NSH
-	  built-int functions.
-	* vsn/hello:  Removed.  The modified apps/examples/hello is enough "Hello,
-	  World!"
-	* apps/examples/nxconsole:  Add a test of the NX console device.
-	* apps/examples/nxconsole:  The NX console example now supports running
-	  the NuttShell (NSH) within an NX window.
-	* apps/system/readline:  Now uses standard definitions from
-	  include/nuttx/ascii.h and vt100.h
-	* Kconfig, */Kconfig:  Added skeleton Kconfig files to all directories that
-	  may need them.
-
-6.18 2012-05-19 Gregory Nutt <gnutt@nuttx.org>
-
-	* Kconfig:  Continued Kconfig file updates (no longer tracking on a per-file
-	  basis in the ChangeLog)
-	* apps/examples/watchdog:  Add a watchdog timer example.
-	* apps/examples/tiff:  Fix wrong path used for temporary file.
-	* apps/examples/touchscreen:  Standardize the board-specific, touchscreen
-	  initialization interfaces.
-
-6.19 2012-06-15 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/nshlib/nsh_usbdev.c:  Add the capability to use an arbitrary USB
-	  device as the console (not necessarily /dev/console).  This is a useful
-	  option because then you can still use the serial console to debug with.
-	* apps/nshlib/nsh_usbdev.c:  User now has to press ENTER 3 times before
-	  USB console will start.  Otherwise, the USB console starts before there
-	  is anyone at the other end to listen.
-	* apps/nshlib/nsh_usbdev.c and nsh_consolemain.c:  Add support for the USB
-	  capability when a USB console is used.
-	* apps/nshlib/nsh_fscmds.c:  Add the 'mv' command
-
-6.20 2012-07-12 Gregory Nutt <gnutt@nuttx.org>
-
-	* namedapp/exec_namedapp.c - Correct an error when round robin scheduling
-	  is enabled.  The priority of the new, named application was erroneously
-	  being set to the priority of the parent thread; losing its configured
-	  priority.  Reported by Mike Smith.
-
-6.21 2012-08-25 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/include/: Stylistic clean-up of all header files.
-	* apps/modbus and apps/include/modbus:  A port of freemodbus-v1.5.0
-	  has been added to the NuttX apps/ source tree.
-	* apps/examples/modbus:  A port of the freemodbus-v1.5.0 "demo"
-	  program that will be used to verify the FreeModBus port
-	* apps/modbus:  Don't use strerror().  It is just too big.
-	* apps/modbus:  Add CONFIG_MB_TERMIOS.  If the driver doesn't support
-	  termios ioctls, then don't bother trying to configure the baud, parity
-	  etc.
-	* apps/nshlib:  If waitpid() is supported, then NSH now catches the
-	  return value from spawned applications (provided by Mike Smith)
-	* apps/nshlib:  Lock the scheduler while starting built-in applications
-	  in order to eliminate race conditions (also from Mike Smith).
-	* apps/examples/adc, pwm, and qencoder:  Add support for testing
-	  devices with multiple ADC, PWM, and QE devices.
-	* apps/nshlib/nsh_mntcmds.c:  Separated mount-related commands out of
-	  nsh_fscmds.c.  Extended to the mount command so that if no arguments
-	  are provided, then the current mountpoints are enumerated.
-	* apps/nshlib/nsh_mntcmds.c:  Add an NSH df command to list the
-	  properties of mounted file systems.
-	* apps/nshlib/nsh_parse.c:  Extend help command options.  'help' with
-	  no arguments outputs a short list of commands.  With -v lists all
-	  command line details.  A command name can be added to just get
-	  help on one command.
-	* system/readline.c:  If character input/output is interrupted by a
-	  signal, then readline() will try the read/write again.
-	* apps/*/Make.defs:  Numerous fixes needed to use the automated
-	  configuration (from Richard Cochran).
-
-6.22 2012-09-29 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/netutils/thttpd/thttpd_cgi.c:  Missing NULL in argv[]
-	  list (contributed by Kate).
-	* apps/nshlib/nsh_parse.c: CONFIG_NSH_DISABLE_WGET not CONFIG_NSH_DISABLE_GET
-	  in one location (found by Kate).
-	* apps/examples/ostest/prioinherit.c:  Limit the number of test
-	  threads to no more than 3 of each priority.  Bad things happen
-	  when the existing logic tried to created several hundred test
-	  threads!
-	* apps/nshlib/nsh.h:  Both CONFIG_LIBC_STRERROR and CONFIG_NSH_STRERROR
-	  must be defined to use strerror() with NSH.
-	* apps/examples/*/*_main.c, system/i2c/i2c_main.c, and others:  Added
-	  configuration variable CONFIG_USER_ENTRYPOINT that may be used to change
-	  the default entry from user_start to some other symbol.  Contributed by
-	  Kate.
-	* apps/netutils/webserver/httpd/c:  Fix a typo that as introduced in
-	  version r4402:  'lese' instead of 'else' (Noted by Max Holtzberg).
-	* tools/mkfsdata.pl: The uIP web server CGI image making perl script was
-	  moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl
-	  (Part of a larger change submitted by Max Holtzberg).
-	* apps/netutils/webserver, apps/examples/uip, and apps/include/netutils/httpd.h:
-	  The "canned" version of the uIP web servers content that was at
-	  netutils/webserver/httpd_fsdata.c has been replaced with a dynamically
-	  built configuration located at apps/examples/uip (Contributed by
-	  Max Holtzberg).
-	* apps/netutils/webserver:  Several inenhancements from Kate including the
-	  ability to elide scripting and SERVER headers and the ability to map
-	  files into memory before transferring them.
-	* apps/netutils/webserver:  Add ability to map a URL to CGI function.
-	  Contributed by Kate.
-	* apps/nshlib/nsh_mntcmds.c: The changes of 6.21 introduced holes in the
-	  error handling:  Now the number of arguments to mount can be 0 or 4.
-	  Additional parameter checking is required to prevent mysterious errors
-	  (submiteed by Kate).
-	* apps/netutils/webserver/httpd_mmap.c:  Fix errors when the mmap()
-	  length is zero (submitted by Kate).
-	* apps/netutils/webserver/httpd_sendfile.c:  Add and option,
-	  CONFIG_NETUTILS_HTTPD_SENDFILE to transfer files using the NuttX
-	  sendfile() interface.
-	* apps/netutils/discover:  A UDP network discovery utility contributed
-	  by Max Holtzberg.
-	* apps/examples/discover:  A test example for the UDP network discovery
-	  utility (also contribed by Max Holtzberg).
-	* apps/examples/*/main.c:  Too many files called main.c.  Each renamed
-	  to something unique so that they will not collide in the archive.
-	* apps/netutils/xmlrpc: The Embeddable Lightweight XML-RPC Server
-	  discussed at http://www.drdobbs.com/web-development/\
-	  an-embeddable-lightweight-xml-rpc-server/184405364.  Contributed by
-	  Max Holtzberg.
-	* apps/netutils/uip_listenon.c:  Logic in uip_server.c that creates
-	  the listening socket was moved to this new file to support re-use.
-	  Contributed by Kate.
-	* apps/netutils/webserver/httpd.c:  The option CONFIG_NETUTILS_HTTPD_SINGLECONNECT
-	  can now be used to limit the server to a single thread.  Option
-	  CONFIG_NETUTILS_HTTPD_TIMEOUT can be used to generate HTTP 408 errors.
-	  Both from Kate.
-	* apps/netutils/webserver/httpd.c:  Improvements to HTTP parser from
-	  Kate.
-	* apps/netutils/webserver/httpd.c:  Add support for Keep-alive connections
-	  (from Kate).
-	* apps/NxWidget/Kconfig:  This is a kludge.  I created this NxWidgets
-	  directory that ONLY contains Kconfig.  NxWidgets does not live in
-	  either the nuttx/ or the apps/ source trees.  This kludge makes it
-	  possible to configure NxWidgets/NxWM without too much trouble (with
-	  the tradeoff being a kind ugly structure and some maintenance issues).
-	* apps/examples/Make.defs: Missing support for apps/examples/watchdog.
-	* apps/NxWidgets/Kconfig:  Add option to turn on the memory monitor
-	  feature of the NxWidgets/NxWM unit tests.
-
-6.23 2012-11-05 Gregory Nutt <gnutt@nuttx.org>
-
-	* vsn: Moved all NSH commands from vsn/ to system/.  Deleted the vsn/
-	  directory.
-	* Makefile:  Change order of includes when CONFIG_NEWCONFIG=y.  In
-	  that case, namedapp must be included first so that the namedapp
-	  context is established first.  If the namedapp context is established
-	  later, it will overwrite any existing namedapp_list.h and nameapp_proto.h
-	  files.
-	* CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences
-	  of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*.
-	* Kconfig:  Fleshed out apps/examples/adc/Kconfig and apps/examples/wget/Kconfig.
-	  There are still a LOT of empty, stub Kconfig files.
-	* Kconfig:  Fleshed out apps/examples/buttons/Kconfig. There are still a LOT
-	  of empty, stub Kconfig files.
-	* apps/netutils/webserver/httpd.c:  Fix a bug that I introduced in
-	  recent check-ins (Darcy Gong).
-	* apps/netutils/webclient/webclient.c:  Fix another but that I introduced
-	  when I was trying to add correct handling for loss of connection (Darcy Gong)
-	* apps/nshlib/nsh_telnetd.c:  Add support for login to Telnet session via
-	  username and password (Darcy Gong).
-	* apps/netutils/resolv/resolv.c (and files using the DNS resolver): Various
-	  DNS address resolution improvements from Darcy Gong.
-	* apps/nshlib/nsh_netcmds.c:  The ping command now passes a maximum round
-	  trip time to uip_icmpping().  This allows pinging of hosts on complex
-	  networks where the ICMP ECHO round trip time may exceed the ping interval.
-	* apps/examples/nxtext/nxtext_main.c:  Fix bad conditional compilation
-	  when CONFIG_NX_KBD is not defined.  Submitted by Petteri Aimonen.
-	* apps/examples/nximage/nximage_main.c:  Add a 5 second delay after the
-	  NX logo is presented so that there is time for the image to be verified.
-	  Suggested by Petteri Aimonen.
-	* apps/Makefile: Small change that reduces the number of shell invocations
-	  by one (Mike Smith).
-	* apps/examples/elf:  Test example for the ELF loader.

-	* apps/examples/cxxtest:  A test for the uClibc++ library provided by
-	  Qiang Yu and the RGMP team.
-	* apps/netutils/webclient, apps/netutils.codes, and apps/examples/wgetjson:
-	  Add support for wget POST interface.  Contributed by Darcy Gong.
-	* apps/examples/relays:  A relay example contributed by Darcy Gong.
-	* apps/nshlib/nsh_netcmds: Add ifup and ifdown commands (from Darcy
-	  Gong).

-6.24 2012-12-20 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/ostest/roundrobin.c:  Replace large tables with
-	  algorithmic prime number generation.  This allows the roundrobin
-	  test to run on platforms with minimal SRAM (Freddie Chopin).

-	* Makefile, */Makefile:  Various fixes for Windows native build.  Now uses
-	  make foreach loops instead of shell loops.
-	* apps/examples/elf/test/*/Makefile: OSX doesn't support install -D, use
-	  mkdir -p then install without the -D.  From Mike Smith.
-	* apps/examples/relays/Makefile: Reduced stack requirement (Darcy Gong).
-	* apps/nshlib and apps/netutils/dhcpc:  Extend the NSH ifconfig command plus
-	  various DHCPC improvements(Darcy Gong).
-	* apps/nshlib/nsh_apps.c: Fix compilation errors when CONFIG_NSH_DISABLEBG=y.
-	  From Freddie Chopin.
-	* Rename CONFIG_PCODE and CONFIG_FICL as CONFIG_INTERPRETERS_PCODE and
-	  CONFIG_INTERPRETERS_FICL for consistency with other configuration naming.
-	* apps/examples/keypadtest:  A keypad test example contributed by Denis
-	  Carikli.
-	* apps/examples/elf and nxflat:  If CONFIG_BINFMT_EXEPATH is defined, these
-	  tests will now use a relative path to the program and expect the binfmt/
-	  logic to find the absolute path to the program using the PATH variable.

-
-	* Makefiles: Removed dependency of distclean on clean in most top-level
-	  files.  It makes sense for 'leaf' Makefiles to have this dependency,
-	  but it does not make sense for upper-level Makefiles.
-	* apps/namedapp/: Renamed to builtins in preparation for another change.
-	* .context:  Removed the .context kludge.  This caused lots of problems
-	  when changing configurations because there is no easy way to get the
-	  system to rebuild the context.  Now, the context will be rebuilt
-	  whenever there is a change in either .config or the Makefile.
-	* apps/builtin/registry:  Updated new built-in registration logic to handle
-	  cases where (1) old apps/.config is used, and (2) applications ared
-	  removed, not just added.
-	* apps/examples/nettest/Makefile:  Fix an error that crept in during
-	  some of the recent, massive build system changes.
-	* apps/builtin/Makefile:  Need to have auto-generated header files
-	  in place early in the dependency generation phase to avoid warnings.
-	  It is not important if they are only stubbed out header files at
-	  this build phase.
-	* apps/examples/hidbkd: Now supports decoding of encoded special keys
-	  if CONFIG_EXAMPLES_HIDKBD_ENCODED is defined.
-	* apps/examples/hidbkd:  Add support for decoding key release events
-	  as well.  However, the USB HID keyboard drier has not yet been
-	  updated to detect key release events.  That is kind of tricky in
-	  the USB HID keyboard report data.
-	* apps/examples/wlan: Remove non-functional example.
-	* apps/examples/ostest/vfork.c:  Added a test of vfork().
-	* apps/exampes/posix_spawn: Added a test of posix_spawn().
-	* apps/examples/ostest:  Extend signal handler test to catch
-	  death-of-child signals (SIGCHLD).
-	* apps/examples/ostest/waitpid.c:  Add a test for waitpid(), waitid(),
-	  and wait().
-	* builtin/binfs.c:  Add hooks for dup() method (not implemented).
-	* builtin/exec_builtin.c, nshlib/nsh_parse.c, and nshlib/nsh_builtin.c:
-	  NSH now supports re-direction of I/O to files (but still not from).
-	* builtin/binfs.c:  Greatly simplified (it is going to need to be
-	  very lightweight).  Now supports open, close, and a new ioctl to recover
-	  the builtin filename.  The latter will be needed to support a binfs
-	  binfmt.
-	* builtin/binfs.c:  Move apps/builtin/binfs.c to fs/binfs/fs_binfs.c
-	  CONFIG_APPS_BINDIR rename CONFIG_FS_BINFS
-	* apps/include/builtin.h:  Some of the content of
-	  apps/include/apps.h moved to include/nuttx/binfmt/builtin.h.
-	  apps/include/apps.h renamed builtin.h
-	* apps/builtin/exec_builtins.c:  Move builtin
-	  utility functions from apps/builtin/exec_builtins.c to
-	  binfmt/libbuiltin/libbuiltin_utils.c
-	* apps/nshlib/nsh_mountcmds.c:  The block driver/source
-	  argument is now optional.  Many files systems do not need
-	  a source and it is really stupid to have to enter a bogus
-	  source parameter.
-	* apps/nshlib/nsh_fileapp.c:  Add the ability to execute a file
-	  from a file system using posix_spawn().
-	* apps/builtin/: Extensions from Mike Smith.
-	* apps/examples/ftpd/Makefile: Name ftpd_start is not the name of
-	  the entrypoint.  Should be ftpd_main (from Yan T.)
-	* apps/netutils/telnetd/telnetd_driver: Was stuck in a loop if
-	  recv[from]() ever returned a value <= 0.
-	* apps/examples/nettest and poll:  Complete Kconfig files.
-	* apps/examples/ostest/waitpid.c:  Need to use WEXITSTATUS()
-	  to decode the correct exit status.
-	* apps/system/usbmonitor:  A daemon that can be used to monitor USB
-	  trace outpout.
-	* apps/nshlib/nsh_usbdev.c, nsh_consolemain.c, nsh_session.c, nsh_script.c:
-	  Add support for a login script.  The init.d/rcS script will be executed
-	  once when NSH starts; the .nshrc script will be executed for each session:
-	  Once for serial, once for each USB connection, once for each Telnet
-	  session.
-	* apps/system/readline: Correct readline() return value.  Was not
-	  any returning special values when end-of-file or read errors
-	  occur (it would return an empty string which is not very useful).
-
-6.26 2013-03-15 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/builtin/exec_builtin.c:  Now uses task_spawn() to start
-	  builtin applications.
-	* Type of argv has changed from const char ** to char * const *
-	* apps/nshlib/nsh_parse.c:  Fix memory lead: Need to detach after
-	  creating a pthread.
-	* apps/examples and nshlib:  Change name of _TCB to struct tcb_s to
-	  match NuttX name change.
-	* apps/examples/ostest/restart.c:  Add a test case to verify
-	  task_restart().
-	* apps/system/readline.c:  readline() now returns EOF on any failure
-	  (instead of a negated errno value).  This is because the underlying
-	  read is based on logic similar to getc.  The value zero was being
-	  confused with a NUL.  So if a NUL was received, the NSH session
-	  would terminate because it thought it was the end of file.
-
-6.27 2013-04-28 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/system/ramtest:  Add a simple memory test (2013-03-26).
-	* apps/examples/ostest:  In the non-cancelable thread test, we need
-	  to give the thread an opportunity to run and to set the non-
-	  cancelable state.
-	* apps/nshlib/nsh_ddcmd.c: Correct the test of the skip input
-	  parameter.  Was limiting the range to <= count.  From Ken
-	  Pettit (2014-4-24).
-
-6.28 2013-06-14 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/mtdpart:  Provides a simple test of MTD partitions.
-	* apps/nshlib/nsh_mntcmds.c:  Add a -h option to the df command to show
-	  the volume information in human readable form (Ken Pettit, 2013-4-30).
-	* apps/nshlib/nsh_fscmds.c: Add support for the mksmartfs command.
-	  (Ken Pettit, 2013-4-30).
-	* apps/system/flash_eraseall:  Add an interface to erase FLASH using a
-	  flash_eraseall NSH command  (Ken Pettit, 2013-5-1).
-	* apps/examples/flash_test and apps/examples/smart_test:  Add tests of
-	  the SMART block driver and file system  (Ken Pettit, 2013-5-1).
-	* apps/examples/mtdpart:  Extended the test.  The original test
-	  coverage was superficial (2013-5-3).
-	* apps/examples/smart:  This is an adaptation of the NXFFS stress
-	  test for the SMART file system (Ken Pettit, 2013-5-3).
-	* apps/examplex/nxtext:  Remove the CONFIG_EXAMPLES_NXTEXT_NOGETRUN
-	  option.  The test logic was bad for the case where this options
-	  is not selected.  Also, complete the empty Kconfig file (2013-5-7).
-	* apps/NxWidgets/Kconfig:  Updated to match NxWidgets/Kconfig by
-	  Ken Pettit (2013-5-11).
-	* apps/examples/helloxx:  C++ name mangling was occurring when this
-	  example is built as an NSH built-in application.  (2013-5-16).
-	* apps/netutils/discover:  Added a runtime configuration for the
-	  UDP discover utility.  From Max Holtzberg (2013-5-21).
-	* apps/examples/tcpecho:  Added a simple single threaded, poll based
-	  TCP echo server based on W. Richard Stevens UNIX Network Programming
-	  Book.  Contributed by Max Holtzberg (2013-5-22).
-	* apps/examples/slcd:  Add an example for testing alphanumeric,
-	  segment LCDs (2013-5-24).
-	* apps/examples/slcd:  Extend SLCD test to handle multi-line displays
-	  (2013-5-26).
-	* apps/examples/slcd:  This test now sets the SLCD brightness level to
-	  the mid-point as part of its initialization (2013-5-27).
-	* .gitignore:  Clean-up of most all .gitignore files:  Make scope of
-	  ignore to be only the current directory; Ignore .dSYM files in
-	  directories where .exe's may be build.  Also, in Makefiles,
-	  clean .dSYM files in directories where .exe may be built (2013-5-30).
-	* apps/examples/nrf35l01_term: Add an example application to demo the
-	  nRF24L01 driver.  From Laurent Latil (2013-6-1).
-	* apps/nshlib/Kconfig:  Add some missing NSH configuration values.
-	  From Lorenz Meier (2013-6-2).
-	* Standardize on CONFIG_NSH_BUILTIN_APPS.  Remove all other variants
-	  of the build-as-an-NSH-application configuration settings
-	  (2013-6-12).
-
-6.29 2013-07-31 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/nsh, cxxtest, and helloxx:  C++ initializers should be
-	  set once and, preferably, in the context of the task that uses any C++
-	  statically initialized classes.  These only becomes an issue if cxxtest
-	  or helloxx are built as NSH builtin applications.  Then you want the
-	  initialization done in cxxtext or helloxx and not in NSH (and certainly
-	  not twice).  Added configuration options to control who does the C++
-	  initialization.  NSH now does not do C++ initialization be default and
-	  must be configured to do otherwise.  Converely, cxxtest and helloxx
-	  will do C++ initialization unless configured do otherwise (2013-6-21).
-	* apps/examples/cxxtext:  Add ostream test as provided by Michael
-	  (2013-6-21).
-	* apps/examples/nxhello:  Minor fix for compilation error when the
-	  display resolution is low (< 8bpp) due to a typo that has been there
-	  for a long time (2013-6-23).
-	* apps/examplex/nxhello:  Correct default colors when in Y1 code mode.
-	  (2013-6-24).
-	* apps/system/Make.defs and Kconfig:  The RAM test was not correctly built
-	  into the configuration and build system (2013-6-26).
-	* apps/examples/composite/composite_main.c:  SourceForge But Ticket #19.
-	  Change to prevent some false alarm debug assertions (From Chia Cheng
-	  Tao, 2013-7-9).
-	* apps/system/zmodem:  Add configuration support and a build framework
-	  for the Zmodem sz and rz command (which exist but have not yet been
-	  checked in) (2013-7-12).
-	* apps/system/zmodem:  The 'sz' command is now complete and seems
-	  functional (given on light testing).  The rz command logic exists but
-	  is still untested and not yet checked in  (2013-7-13).
-	* apps/system/zmodem:  The 'rz' command is now complete and functional
-	  under certain conditaions.  There are, however, some data overrun
-	  issues that I am still uncertain how should be handled (2012-7-15).
-	* apps/system/zmodem/Makefile.host and host/: The Zmodem utilities
-	  can now be built to execute on a Linux host.
-	* apps/nshlib/nsh_fscmds.c:  Add a 'cmp' command that can be used to
-	  compare two files for equivalence.  Returns an indication if the files
-	  differ.  Contributed by Andrew Tridgell (via Lorenz Meier) (2013-7-18).

-6.30 2013-09-14 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/composite/:  SourceForge bug #19: Fix a typo that can
-	  cause a configuration error.  From CCTSAO (2013-9-4).
-	* apps/examples/cc3000.  Initial support for the TI CC3000 network module
-	  on the Freescale Freedom-KL25Z board from Alan Carvalho de Assis.
-	  Includes the test to verify the CC3000 (2013-9-3).
-	* apps/examples/usbmsc:  apps/examples/usbstorage renamed usbmsc.
-	  Change submitted by CCTSAO (2013-6-5).
-	* apps/examples/pwm:  Clean-up some configuration confusion (2013-9-5).
-	* apps/netutils/dhcpd/dhcpd.c:  Fix calculation of the next lease
-	  address.  SourceForge bug #21 from Paolo Messina (2013-9-6).
-	* apps/examples/usbmsc:  Don't try to control USB trace if we are
-	  an NSH built-in task.  In that case our attempts are inadequate
-	  and only interfere with with other logic that is attempting to
-	  to do the same thing (in NSH or in the USB monitor) (2013-9-6).
-	* apps/examples/usbmsc:  IMPORTANT bug fix: Change how the msconn
-	  works.  Because of recent changes the msconn command was hanging.
-	  This was because the USB MSC start-up logic creates a pthread;
-	  Now waitpid() will wait until all members of the task group
-	  exit.  So NSH was hanging in waitpid when msconn started even
-	  though msconn returned.  The USB MSC logic really should not use
-	  a pthread, but we are stuck with that for now.  The work-around
-	  is that msconn now daemonizes itself so that it so that the pthread
-	  is created in a different task group (2013-9-7).
-	* apps/system/usbmonitor:  The USB monitor has been extended so
-	  that it can be used with USB device or host trace data (2013-9-9).
-	* apps/nshlib/nsh_fscmds.c:  Fix NSH listing output for the case
-	  of a single file.  Provided by Lorenz Meier (2013-9-13).
-
-6.31 2013-10-28 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/nshlib/nsh_netcmds.c:  Remove a warning when DHCP is not
-	  enabled (2013-9-17).
-	* apps/nshlib/Kconfig:  Default IP address should be 0x0a000001
-	  (10.0.0.1), not 0xa0000001 (160.0.0.1).  Ditto for the gateway
-	  (2013-9017).
-	* apps/examples/ostest/Kconfig:  Add configuration options for
-	  the FPU test.  There are still many OS test configuration
-	  options that do not appear in Kconfig (2013-9-18).
-	* apps/examples/cc3000:  Condition the CC3000 example on having
-	  selected the CC3000 device.  Otherwise, you are prompted for
-	  this option on each 'make oldconfig' (2013-9-18).
-	* apps/system/usbmonitor/usbmonitor.c:  Fix some bad conditional
-	  compilation probably introduced on 2013-9-9 (2013-9-23).
-	* apps/system/stackmonitor:  Add a daemon that can be used to
-	  monitor stack usage by all threads (2013-9-24).
-	* system/usbmsc:  Move examples/usbmsc to system/usbmsc (2013-9-25).
-	* system/cdcacm:  Move examples/cdcacm to system/cdcacm (2013-9-25).
-	* system/composite:  Move examples/composite to system/composite
-	  (2013-9-25).
-	* apps/nshlib and apps/readline:  Numerous changes to get NSH
-	  working with no file system.  Basically this suppresses I/O
-	  redirection and replaces file I/O with calls to low-level
-	  console read/write functions.  Suggested by Alan Carvalho de Assis
-	  in a somewhat different form. (2013-9-30).
-	* apps/nshlib/nsm_routecmds.c:  Add addroute and delroute
-	  commands (2013-10-5).
-	* apps/system/i2ctool/Kconfig:  Fix default I2C frequency:  400KHz
-	  instead of 4MHz.  Suggested by Max Kriegleder (2013-10-10).
-	* apps/system/info/Kconfig and Makefile:  Increase stack size.
-	  Ken Pettit reports that this simple command can exceed its 768
-	  stack size under certain conditions.  The size is marginal and
-	  has been increased to 1024 by default but is also now configurable
-	  (2013-10-14).
-	* apps/Makefile:  Need to include external/Make.defs if we want
-	  allow external applications to participate in the NuttX
-	  configuration.  Suggested by gdi@embedders.org (2013-10-14).
-	* apps/examples/cc3300: Updates as part of larger re-organizaion
-	  of CC3000 logic by David Sidrane (2013-10-16).
-	* apps/examples/random:  Add a simple test that dumps values from
-	  /dev/random (2013-10-20).
-	* apps/examples/cc3000:  Extensions and enhancements from David
-	  Sidrane (2013-10-23).
-	* apps/netutils/telnetd/telnetd_driver.c:  Missing argument to
-	  debug statement can cause crashes in certain error conditions.
-	  From David Sidrane (2013-10-24).
-	* apps/examples/cc3000:  Updates from David Sidrane.  Plus
-	  some kruft removal (2013-10-24).
-	* apps/examples/can/can_main.c:  Correct an error in a debug
-	  statement.  From Martin Lederhilger (2013-10-24).
-	* apps/examples/adc:  Add support so that a ADC driven by
-	  software triggering can be tested (2013-10-25).
-	* apps/examples/cc3000:  Updates from David Sidrane (2013-10-25).
-	* apps/system/nxplayer:  Implements a command line media
-	  player.  From Ken Pettit (2013-10-27).
-	* apps/system/nxplayer: Add logic to verify the audio sub-format.
-	  From Ken Pettit (2013-10-28).

-
-	* apps/platform:  A new home for board-specific application code
-	  (2013-10-30).
-	* apps/include/platform/configdata.h:  Define an interface that can be
-	  used to manage platform-specific storage of configuration data
-	  (2013-10-30).
-	* apps/examples/cc3000: Fine tuning of memory usage from David Sidrane
-	  (2013-10-30).
-	* apps/platform/mikroe-stm32f4: Now supports storage of configuration
-	  data.  From Ken Pettit (2013-10-30).
-	* apps/nshlib/nsh_dbgcmds.c and others:  Add skip= and count=
-	  options to the hexdump command.  From Ken Pettit (2013-11-1).
-	* apps/platform/mikroe-stm32f4:  Now uses /dev/config for configuration
-	  data storage.  From Ken Pettit (2013-11-1).
-	* apps/platform/Makefile:  Was not dealing with the bin sub-directory
-	  correctly (2013-11-2).
-	* apps/examples/configdata:  A unit test for the MTD configuration
-	  data driver from Ken Pettit (2013-11-4).
-	* apps/platform/mikroe-stm32f4:  Updated to use new MTD configuration
-	  driver features.  From Ken Pettit (2013-11-1).
-	* apps/nshlib/nsh.h:  Allow USB trace without a USB console. From
-	  David Sidrane (2013-11-06).
-	* apps/system/composite/composite_main.c:  The wrong handle was getting
-	  nullified.  From David Sidrane (2013-11-7).
-	* apps/system/nxplayer: Play thread stack size is now configurable.  All
-	  NxPlayer threads now have names assigned via pthread_setname_np().
-	  From Ken Pettit (2013-11-10).
-	* apps/examples/i2schar:  The beginning of an I2S test based on the I2S
-	  character driver (2013-11-10).
-	* apps/nshlib/nsh_mntcmds.c:  Mount command updates from Ken Pettit
-	  (2013-11-17).
-	* apps/examples/hidkbd/hidkbd_main.c:  Now calls a function named
-	  arch_usbhost_initialize() that must be provided by the platform-
-	  specific code (2013-11-29).
-	* apps/nshlib/nsh_fscmds.c:  Add an option to the mkfatfs command to
-	  specify FAT12, FAT16, or FAT32 (2013-12-5).
-
-6.33 2014-01-30 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/nshlib/nsh_mntcmds.c:  Modified the df -h logic to eliminate
-	  truncating numbers in conversion (like 7900 -> 7M).  From Ken
-	  Pettit (2013-12-12).
-	* Moved configs/stm3240g-eval/src/up_cxxinitialize.c to
-	  apps/platform/stm3240g-eval/up_cxxinitialize.c:  Now it is available
-	  in user-space in the kernel mode build (2013-12-29).
-	* apps/examples/mount/Kconfig:  Fill in empty Kconfig file (2013-12-31).
-	* builtin/Makefile: Fixes for native Windows build from Max Holtzberg
-	  (2014-1-4).
-	* apps/netutils/dhcpc/Kconfig, resolv/Kconfig, telnetd/Kconfig, and
-	  apps/nshlib/Kconfig:  Refactor some configuration dependencies:  NSH
-	  features should depend on netutil selections; netutil selections
-	  should depend on networking selections. (2014-1-9).
-	* apps/nshlib/nsh_command.c:  Separate NSH command handling from NSH
-	  line parsing.  This re-partitioning simplifies the logic and will
-	  enable some things to come (2014-1-10).
-	* apps/nshlib/nsh_parse.c:  Will now support multiple commands on a
-	  command line, each separated with a semi-colon (2014-1-10).
-	* apps/nshlib/nsh_parse.c:  Put the logic that executes a command
-	  after parsing parameters into a separate file so that it can be
-	  reused (2014-1-10).
-	* apps/nshlib/nsh_parse.c:  Add initial support of commands enclosed
-	  in back quotes as command arguments.  Functionality still incomplete
-	  on initial commit (2014-1-10).
-	* Logic to support commands enclosed in back quotes is functional
-	  but not thoroughly tested (2014-1-11).
-	* apps/nshlib/nsh_parse.c:  Can now handle arguments that are
-	  concatenations of constant strings, command return data, application
-	  return data, and environment variables (2014-1-11).
-	* apps/nshlib/nsh_parse.c:  Fix a memory leak ... forgot to close
-	  a temporary file (2013-1-12).
-	* apps/system/inifile:  A simple INI file parser (perhaps too simple).
-	  This is code that I wrote a long time ago and have used many time but
-	  is untested in its current incarnation (2014-1-15).
-	* aps/nshlib/nsh_parse.c:  Recent changes broke redirection of output
-	  (2014-1-14).
-	* apps/nshlib/nsh_parse.c:  Add true and false commands (2014-1-17)
-	* apps/nshlib/nsh.h and nsh_parse.c:  Re-name and re-organize some
-	  if-then-else related structures to better support forthcoming until
-	  and while loops (2014-1-17).
-	* apps/nshlib/nsh_script.c:  Now saves the FILE stream for the script
-	  file in the vtbl structure so that it can be accessed by forthcoming
-	  while and until logic (2014-1-17).
-	* apps/nshlib/nsh.h, nsh_command.c, nsh_parse.c, and nsh_script.c:  Add
-	  support for while-do-done and until-do-done loops.  These only work
-	  when executing a script file because they depend on the ability to seek
-	  in the file to implement the looping behaviors (2014-1-17).
-	* apps/nshlib/nsh_parse.c:  Loosen up if-then-else-fi syntax to allow
-	  a command to be on the same line as the then and else tokens like:
-	  "if true; then echo true; else echo false; fi".  Much more like bash!
-	  (2014-1-17).
-	* apps/nshlib/Kconfig, README.txt, nsh.h, nsh_command.c, and
-	  nsh_script.c:  Add an option to conditionally compile out support for
-	  loop and for if-then-else-fi sequence (2014-1-17).
-	* apps/nshlib/nsh.h, nsh_command.c, and nsh_parse.c:  Add a break
-	  command that can be executed with a loop to terminate the loop
-	  immediately (2014-1-17).
-	* apps/system/vi:  Add support for a tiny, VI work-alike editor.  This
-	  is still very much a work-in-progress on initial check-in (2014-1-20).
-	* apps/netutils/uiplib:  Support new definitions and state passing for
-	  network device status. From Maz Holtzberg (2014-1-21).
-	* apps/system/vi:  Tiny VI is basically functional.  All commands seem
-	  to work.  There are still some display artifacts and probably several
-	  untested conditions (2014-1-21).
-
-7.1 2014-03-15 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/system/cle:  Add a EMACS-like command line editor.  This CLE,
-	  is really more like readline than the NuttX readline is!  (2014-02-02).
-	* apps/nshlib: Use of the standard tiny readline (about .25KB) is now
-	  an option and can be replaces with the EMACX-like CLE (about 2KB)
-	  (2014-02-02).
-	* Several changes to restore Windows native build (2014-2-7)
-	* apps/examples/touchscreen:  Can now be configured to work with a mouse
-	  interface as well (2014-2-10).
-	* Several files changes based on complaints from the tool CppCheck.  Some
-	  latent bugs were fixed (and most likely some new typos were introduced)
-	  (2014-2-10).
-	* apps/examples/nximage/Kconfig and apps/examples/uip/Kconfig: Incomplete
-	  Kconfig files fleshed out by Alan Carvalho de Assis (2014-2-18).
-	* apps/nshlib: 'rmdir' can now be used in the pseudo-filesystem.  Hence,
-	  the command needs to be available even if there are no write-able
-	  filesystem enabled (2014-2-19).
-	* apps/nshlib: 'mkdir' can now be used in the pseudo-filesystem.  Hence,
-	  the command needs to be available even if there are no write-able
-	  filesystem enabled (2014-2-19).
-	* apps/nshlib: 'mv' can now be used in the pseudo-filesystem.  Hence,
-	  the 'mv' command needs to be available even if there are no write-able
-	  filesystem enabled (2014-2-19).
-	* apps/nshlib: 'rm' can now be used to remove nodes from the pseudo-
-	  filesystem.  Hence, the 'rm' command needs to be available even if there
-	  are no write-able filesystem enabled (2014-2-20).
-	* CONFIG_DISABLE_PSEUDOFS_OPERATIONS: This new configuration setting
-	  basically backs out the recent changes to mv, rm, mkdir, and rmdir
-	  (2014-2-20).
-	* nshlib/Kconfig:  Use CONFIG_DEFAULT_SMALL in selecting default
-	  settings (2014-2-20).
-	* nshlib/nsh_telnetd.c:  Use strncpy vs strcpy to avoid overrunning the
-	  username and password buffers.  From Bertold Van den Bergh (2014-2-22).
-	* nshlib/Kconfig, nsh_proccmds.c:  If the CPU load feature and the procfs
-	  features are enabled, then show CPU load used by each thread in the
-	  'ps' command (2014-2-27).
-	* nshlib/nsh_fscmds.c:  Add a newline after printing the file in the
-	  'cat' command.  This prevents the NSH prompt from be in the same line
-	  as the final line of the file in the case where there is no newline
-	  at the end of the file (2014-2-27).
-	* netutils/dhcpd/dhcpd.c: allocipaddr() should not call ntohl(), the
-	  returned IP address is already in host order.
-	* apps/netutils/dhcpd/Kconfig: Add missing DHCPD configuration
-	  settings(2014-3-3).
-	* Support for the legacy configuration mechanism (using appconfig files)
-	  is removed.  Only the newer configuration using the kconfig-frontends
-	  tools is now supported (2014-3-6).
-
-7.2 2014-04-29 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/nshlib/nsh_parse.c: Fix NuttShell version number display in
-	  welcome message.  version.h was not being included (2014-3-23).
-	* apps/examples/igmp:  Fill out Kconfig file; update makefile so
-	  that the IGMP example can be used as an NSH built-in application.
-	  From Manuel St�hn (2014-3-24).
-	* apps/system/usbmsc:  Back out the USBMSC daemon... it is no longer
-	  needed with the recent fix to the USBMSC class driver (2014-3-25).
-	* apps/examples/lcdrw:  Fill out empty Kconfig file (2014-2-27).
-	* apps/netutils/dhcpd/dhcpd.c:  The correct value of the PAD option
-	  is zero, not one.  From Brennan Ashton (2014-3-31).
-	* apps/sysinfo:   CONFIG_VERSION_BUILD is a string an needs to be
-	  printed with %s, not %d.  Noted by Librae (2014-4-8).
-	* apps/netutils/ntpclient/ and apps/include/netufils/ntpclient.h:  Add
-	  a very primitive NTP client.  The initial check-in is untested and
-	  probably incomplete (2014-4-10).
-	* apps/netutils/resolv:  Long needed major clean up for coding style
-	  and unification of naming conventions (resolv vs dns) (2014-4-11).
-	* apps/netutils/dnsclient and include/netutils/dnsclient.h:  File name
-	  changes that are part of the overal resolv->dns renaming (2014-4-11).
-	* apps/netutils/dnsclient:  Break the one big monolithic file into
-	  three smaller files (2014-4-11).
-	* apps/netutils/ntpclient/ntpclient.c: Corrections to the NTP client
-	  from Manuel Stuehn (2014-4-12).
-	* apps/examples/touchscreen:  Add a configuration option to indicate if
-	  architecture-specific initialized is required, yes or no (2014-4-14).
-	* apps/system/nxplayer/nxplayer.c:  Compilation failure in one
-	  configuration reported by Manuel Stuhn (2014-4-21).
-	* apps/system/sdcard:  Remove an STM32 dependency.  From Bob Doiron
-	  (2014-4-21).
-	* apps/nshlib: malloc/free IOBUFFER for 'cat' and 'hexdump' commands
-	  instead of using the stack.  From Bob Doiron (2014-4-21).
-	* apps/examples/cpuhog, serialblaster, and serialrx:  Stress test
-	  examples added by Bob Doiron (2014-4-22).
-	* apps/examples/telnetd:  Naming is confused.  In someplaces 'telnetd',
-	  and in others 'shell.'  All changes to telnetd.  Noted by Pelle
-	  Windestam (2014-4-38).
-
-7.3 2014-06-25 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/serialblaster:  Update configuration an make logic in
-	  order to select that the serial blaster task priority and stack size.
-	  From Bob Doiron (2014-4-30).
-	* apps/nshlib/Kconfig and other NSH files:  The alternate console device
-	  CONFIG_NSH_CONDEV must not be defined unconditionally.  This causes errors
-	  when using Telnet sessions.  This was solved by adding CONFIG_NSH_ALTCONDEV:
-	  CONFIG_NSH_ALTCONDEV enables or disables the feature then, if enabled,
-	  CONFIG_NSH_CONDEV provides the alternative console device name (2014-5-5).
-	* apps/system/i2c/i2c_get.c:  Fix to show the updated register address on
-	  each fetch (vs. showing the same starting address each time).  From
-	  Ryan VanSickle (2014-5-8).
-	* apps/interpreters/prun and apps/include/interpreters/prun.h:  Broke out
-	  the P-code execution logic from apps/examples/pashello and moved it to
-	  these directory where it can be used more generally (2014-5-9).
-	* apps/system/prun and apps/include/interpreters/pexec_main.c:  Move the
-	  P-Code execution logic from apps/interpreters/prun to
-	  apps/system/prun; Add pexec_main.c which is an NSH built-in
-	  application that can be used to run P-Code programs from the NSH
-	  command line (2014-5-9).
-	* Several files: Convert all old-style variadic macros to the C99 form.
-	  Recent GCC changes tightens up that behavior and can cause some problems
-	  (at least for the IAR compiler for some reason).  See
-	  https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html#Variadic-Macros.
-	  Noted by Bob Grimes (2014-5-22).
-	* apps/system/cle:  CLE was not returning the terminating newline character.
-	  But reported by Max kriegleder; work-around reported by Lorenz Meier
-	  (2015-5-23).
-	* Misc changes due to moving nuttx/net/uip/uip-arp.h to nuttx/net/arp.h
-	  (2015-5-30).
-	* apps/examples/netpkt/:  A "raw" socket test from Lazlo Sitzer
-	  (2014-6-12).
-	* apps/system/hex2bin/:  A library and built-in task to convert from
-	  Intel HEX to binary format.  Untested on initial commit (2014-6-15).
-	* apps/system/hex2bin/: Appears to be functional but testing is still
-	  light (2014-6-16).
-	* apps/system/hex2bin/hex2mem_main: Add a variant application that will
-	  write Intel HEX files directly to memory (2014-6-16).
-	* netutils/webserver: httpd_fs_open() should return OK on success and
-	  ERROR on failure, not 1 and 0 (2014-6-23)
-
-7.4 2014-08-15 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/system/mdio:  PHY tool from Daniel Lazlo Sizter (2014-6-27).
-	* apps/nshlib:  Networking logic modified to handler the case of SLIP
-	  transport.  From Max Neklyudov (2014-6-27).
-	* apps/nshlib:  if # appears on line, need to comment ignore additional
-	  commands on the line (2014-7-1).
-	* apps/netlib: Renamed all occurrences of uiplib to netlib.  Renamed
-	  files under netutils/uiplib/uip_*.c to netutils/netlib/netlib_*.c.
-	  Renamed all functions defined in netutils/netlib/ to begin with netlib_,
-	  instead of uip_. (2014-7-2).
-	* apps/nshlib/nsh_usbkeyboard.c:  Add a configuration to use a USB
-	  keyboard for the stdin device (2014-7-3).
-	* apps/neturils/webclient/webclient.c:  Fix to offset calculation from
-	  Rony Xln.  Prevents 0x0a at the beginning of lines (2014-7-7).
-	* netutils/webserver (and other files):  Fix some configuration usage:
-	  CONFIG_NETUTILS_HTTPD_SENDFILE was missing from Kconfig; CONFIG_NET_HAVE_SOLINGER
-	  should be CONFIG_NET_SOLINGER; Type of CONFIG_NET_HTTPD_MAXPATH was wrong
-	  in Kconfig file.  From Max (2014-7-11).
-	* apps/system/nxplayer/nxplayer.c:  Check for file read errors and end-of-file
-	  with zero bytes read (2014-7-23).
-	* apps/system/nxplayer: Misc changes to better integrate with
-	  NxWM::CMediaPlayer (2014-7-23).
-	* apps/system/nxplayer/nxplayer.c and apps/include/nxplayer.h: Add hooks
-	  for fast-forward and rewind needed by CMediaPlayer; add hooks for
-	  equalizer settings needed by the WM8904  (2014-7-24).
-	* apps/include/nxplayer.h and apps/system/nxplayer/nxplayer.c: Changes to
-	  integrate with Ken's NxWM::CMediaPlayer (2014-7-24).
-	* apps/include/nxplayer.h: Move subsampling rate definitions from nxplayer.h
-	  to audio.h *2014-7-27).
-	* apps/system/nxplayer/nxplayer.c: NxPlayer needs to set curbyte field to
-	  zero before enqueuing a buffer.  Otherwise, it looks like beginning of
-	  the buffer has already been consumed. (2014-7-27).
-	* apps/netutils/webserver/httpd.c:  Missing logic to close sockets on loop
-	  termination.  From Max (2014-7-28).
-	* apps/system/nxplayer/nxplayer.c:  Fix some error handling, update
-	  comments, more debug output (2014-7-31).
-	* apps/system/nxplayer/nxplayer.c: Change how the end of the audio
-	  stream is detected by the leaf audio component.  This used by be done
-	  by looking for the first partial buffer.  That does not work with the
-	  in-place sub-sampling performed by the PCM decoder:  That always reduces
-	  the size of the buffer so that all buffers only partially filled by the
-	  time they get to the leaf.  Now, a flag is set in the audio buffer
-	  flags set to indicate the final buffer in the stream (2014-7-31).
-	* apps/system/nxplayer/nxplayer.c: Fix an error I introduced:  Need to
-	  pass through final buffer even if is it zero length because it contains
-	  the end of audio stream flag (2014-8-1).
-	* apps/system/nxplayer/nxplayer.c: Break reading and enqueueing of audio
-	  buffers into two steps so that errors in enqueueing can be
-	  distinguished from errors in reading.  Errors in enqueueing signal a
-	  downstream decoder error.  Add logic to gracefully recover from
-	  downstream decoder errors (2014-8-5).
-	* apps/nshlib/Kconfig, nsh.h, and nsh_netinit.c: Software assigned MAC
-	  address is now configurable. From Lazlo (2014-8-6).
-	* apps/nshlib/Kconfig, nsh.h, and nsh_netinit.c: Also add an option to
-	  let platform-specific logic select the MAC address (2014-8-5).
-	* apps/nshlib/Kconfig, nsh.h, and nsh_netinit.c:  There is now a
-	  configuration option that will bring up the network on an separate
-	  thread.  Since the network bring-up is asynchronous, there are not
-	  serial console start-up delays due to the network negotiation time
-	  (2014-8-6).
-	* apps/system/sudoku:  Add a sudoku game (2014-8-11).
-
-7.5 2014-09-28 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/nshlib/Kconfig, nsh.h, and nsh_netinit.c:  Extend the NSH network
-	  initialization logic.  There is now an option that will create a
-	  network monitor thread that will monitor the state of the link.  When
-	  the link goes down, the code will attempt to gracefully put the
-	  Ethernet driver in a down state; When the link comes back, the code
-	  will attempt to bring the network back up (2014-8-17).
-	* apps/system/free/free.c and install/install.c: STM32 FLASH fixes:
-	  use size_t instead of uint16_t, make interface more generic.  From
-	  Freddie Chopin (2014-8-28).
-	* apps/examples/elf:  The ELF test/example has been extended so the
-	  individual ELF test programs can link against the SYSCALL library
-	  (if it is available) or against the C library to eliminate or
-	  minimize the need for symbol tables (2014-8-29).
-	* apps/nshlib/nsh_proccmds.c: Fix NSH PS command:  If there are no
-	  arguments, it would print garbage for argument list (2014-9-1).
-	* apps/import/, apps/tools/, apps/Makefile: Beginning of logic that
-	  will, hopefully, allow me to build applications against a NuttX export
-	  package (vs. the nuttx/ source tree) (2014-9-4).
-	* apps/tools/mkimport.sh and apps/import/Makefile: Add .config file to
-	  export package (2014-9-5).
-	* apps/Makefile: Add a 'make import' target.  More is needed before
-	  it will be usable (2014-9-5).
-	* apps/import/Make.defs and .gitignore: Added mostly empty Make.defs
-	  file.  Something like this will be bee needed for the 'make import'
-	  build (2014-9-5).
-	* apps/Makefile, examples/elf/Kconfig, and import/Make.defs: Copy more
-	  logic from nuttx/tools/Config.mk into the Make.defs file (2014-9-5).
-	* apps/import/Make.defs: Also need to define CFLAGS (2015-9-5)
-	* apps/import/scripts/gnu-elf.ld:  Add GCC linker script for ELF
-	  import builds (2014-9-5).
-	* All Makefiles:  Add an install target to all makefiles.  For the
-	  import build, the top-level Makefile now does two passes: (1) builds
-	  libapp.a, then (2) installs the programs (not yet finished) (2014-9-6).
-	* Many files:  With kernel build (CONFIG_BUILD_KERNEL), entry point to
-	  all tasks is main, not some xyz_main (2014-9-6).
-	* Many Makefiles: Add program installation for CONFIG_BUILD_KERNEL in
-	  all Makefiles that build a main() (2014-9-6).
-	* Many Makefiles.  For kernel build, the object file containing main
-	  cannot go into library because of name collisions.  The object file
-	  must be handled as a special case in every Makefile (2014-9-7).
-	* apps/import/Make.defs: libapps.a needs to be added to the list of
-	  libraries to link against (2014-9-7).
-	* apps/nshlib/nsh.h and nsh_ddcmd.c: Several commands must be disabled
-	  in the kernel build because they depend on interfaces that are not
-	  available outside of the kernel: dd, df, losetup, mkfatfs, mkdr, and
-	  ps (2014-9-7).
-	* apps/import/Make.defs: ELF build requires -fno-common in CFLAGS
-	  (2014-9-8).
-	* apps/tools/mkromfsimg.sh:  Add a script to create a BOOT ROMFS
-	  filesystem image (2014-9-9).
-	* Many makefiles:  All makefiles that have separated the MAINOBJ
-	  need to include MAINOBJ in list of C objects to be compiled.
-	  SourceForge tick #31 from Aton (2014-9-11).
-	* apps/examples/elf/tests/Makefile and nxflat/tests/Makefile: Do
-	  not build test cases that use task_create if there is an address
-	  environment (2014-9-14).
-	* apps/examples/null/null_main.c:  Need to include config.h it order know
-	  if this is or is not a kernel build (2014-9-16).
-	* Change all occurrences of NxConsole to NxTerm (2014-9-20).
-	* apps/examples/Konfig, Makefile, README.txt and all of mdrwb/: Add an
-	  example to test MTD R/W buffering (2014-9-25).
-	* apps/examples/ostest:  Add a trivial test of sem_timedwait (2014-9-16).
-
-7.6 2014-11-26 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/ostest:  Add a simple test of named semaphores
-	  (2014-9-23).
-	* apps/netutils/webclient/Kconfig and webclient.c: Add implementation of
-	  timeouts for the apps/netutils/webclient.  From Brennan Ashton
-	* apps/nshlib/Kconfig and nsh_romfsetc.c: Add support for a custom NSH
-	  ROMFS startup image header file location.  From Martin Lederhilger
-	  (2014-9-30).
-	* apps/nshlib/nsh_fscmds.c:  Fix ls -l output for regular files (14-9-30).
-	* apps/nshlib/nsh_ddcmd.c: Fix reversed in/out file closing when an
-	  error occurs.  From Ken Pettit (2014-10-2).
-	* apps/examples/ostest/aio.c, Kconfig, Makefile, and ostest_main.c: Add
-	  AIO test case in OS test (2014-10-5).
-	* apps/examples and system:  Remove non-portable uses of syslog
-	  (014-10-8).
-	* apps/: Correct everything under apps to use the corrected syslog
-	  interfaces (2014-10-8).
-	* apps/netutils/netlib/netlib_gethostaddr.c: Fix memcpy of host address
-	  in netlib_gethostaddr().  From Brennan Ashton (2014-10-17).
-	* apps/system/stackmonitor.c and stackmonitor/Makefile: Fix compile
-	  problems introduced when the syslog() prototype changed; Also update
-	  Makefile for kernel build From Radoslaw Adamczyk (2014-10-23).
-	* apps/examples/nxterm/Makefile: Update makefile for kernel-build
-	  issues. From Radoslaw Adamczyk (2014-10-23).
-	* apps/examples/keypadtest/keypadtest_main.c: Fixes to keypadtest from
-	  Pierre-Noel Bouteville (2014-10-23).
-	* apps/nshlib/nsh_parse.c, nsh.h, and Kconfig: Move CONFIG_NSH_TMPDIR
-	  to CONFIG_LIBC_TMPDIR (2014-11-05).
-	* apps/interpreter/bas:  Merged in the Michael Haardt's BAS 2.4 adapted
-	  for use by NuttX by Alan Carvalho de Assis.  The bas24 branch was merged
-	  into the master branch on this date (2014-11-7).
-	* apps/examples/bastest:  This is a special version of Michael
-	  Haardt's BAS 2.4 test files adapted for use by NuttX on a ROMFS file
-	  system (2014-11-7).
-	* apps/interpreter/bas: Add VT100 support for color command (2014-11-10).
-	* nshlib/: Remove use of CONFIG_MAX_TASKS in ps command and in range
-	  checkout (2014-11-13).
-	* netutils/thttpd:  Remove use of CONFIG_MAX_TASKS in in 'task' CGI
-	  example (2014-11-13).
-	* sysm/i2c: Remove use of CONFIG_MAX_TASKS for maximum argument I2C
-	  tool size (2014-11-13).
-	* apps/netutils/dnsclient/dns_socket.c:  Right now if you make a DNS
-	  request before the dns address it set you will get an assertion. The
-	  state of the IP setting is not something the application should be
-	  aware of, it should only be concerned with whether or not the name
-	  was resolved.  From Brennan Ashton (2014-11-13).
-	* apps/nshlib/, apps/netutils, and apps/include/netutils:  Misc
-	  changes to support multiple networks with different link layers.  For
-	  example, ETHERNET + SLIP (2014-11-15).
-	* apps/nshlib/nsh_usbconsole.c:  Add logic to restart the console wait
-	  if an error occurs while reading from the console.In USB console
-	  startup, the logic must be able to open the USB serial and receive 3
-	  newlines.  However, it the USB driver is disconnected or otherwise
-	  fails before the 3 newlines are received, the receive loop becomes a
-	  killer, infinite loop, CPU hog.  Noted by spasbyspas (2014-11-16).
-	* examples/, netutils/, nshlib/, various files:  Rename
-	  CONFIG_NET_BUFSIZE to CONFIG_NET_ETH_MTU; Add CONFIG_NET_SLIP_MTU.
-	  Modify logic to handle different MTUs when both Ethernet and SLIP
-	  are enabled (2014-11-16).
-	* apps/examples/discover, tcpecho, webserver, xmlrpc:  These examples
-	  all set the IP address of eth1 but the netmask and gateway of eth0
-	  if DHCP is enabled.  That can't be right???? (2014-11-17).
-	* apps/examples/bridge:  Add a simple UDP relay bridge for testing
-	  configurations with multiple networks.  Initial checkin is not
-	  very usable because it lacks a host-side test driver for the
-	  bridge (2014-11-17).
-	* apps/netutils/codecs/md5.c: Fix md5 hashing when digest[$i] lower
-	  that 16. From Sergey (2015-11-20).
-	* apps/examples/bridge/host_main.c, host_net1.c, host_net2.c, Kconfig,
-	  and Makefile:  Add host-side test driver (2014-11-21).
-
-7.7 2015-01-26 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/romfs/Makefile: fix romfs example builtin app registry
-	  issue.  From Librae (2014-11-27).
-	* apps/examples/djoystick and support files:  Add a test of the discrete
-	  joystick driver (2014-11-28).
-	* apps/examples/ajoystick and support files:  Add a test of the analog
-	  joystick driver (2014-12-03).
-	* apps/nshlib/nsh_netcmds.c: NSH TFTP get command:  Wrong file namei
-	  used for the destination.  From Lazlo (2014-12-10).
-	* apps/system/cu: Add a minimalist implementation  of the 'cu' terminal
-	  program (part of Taylor UUCP for ages). Using it, you can simply open
-	  a serial port and interact with it. Using '~.' you can leave the
-	  terminal program and drop back to nsh.  This  might come in handy for
-	  people that have e.g. GSM modems, GPS receivers or other devices with
-	  text based serial communications attached to their Nuttx systems. From
-	  Harald Welte (2014-12-13).
-	* apps/examples/ltdc and build-related file: Add ltdc test example. From
-	  Marco Krahl (2014-12-19).
-	* apps/system/cdcacm, composite and usbmsc:  Fix some strangely placed
-	  conditional compilation.  Looks like an automated update gone awry
-	  (2014-12-28).
-	* apps/examples/ltdc/ltdc_main.c:  Clean up documentation, some formatting
-	  improvements.  From Marco Krahl (2014-12-29).
-	* apps/system/lm75 and build-related files:  Add a tiny application to
-	  read the temperature from an LM-75 (or compatible) temperature sensor
-	  (2015-01-06).
-	* apps/interpreters/micropython:  A port of Micro Python to NuttX.
-	  Contributed by Dave Marples (2015-01-11).
-	* apps/examples/timer:  Add a trivial test of the timer driver
-	  (2015-01-13).
-	* apps/netutils/dnsclient:  Can select to be either IPv4 or IPv6, but
-	  not both (IPv6 still does not compile) (2015-01-18).
-	* apps/netutils/netlib:  Add new library functions to manipulate IPv6
-	  addresses (2015-01-13).
-	* apps/nshlib/Kconfig and nsh_netinit.c:  Add logic to initialize
-	  IPv6 addresses (2015-01-19).
-	* apps/netutils/netlib:  All IOCTLs must use a valid address family --
-	  even if the address family does not matter such as when getting the
-	  MAC address or the network flags (2015-01-19).
-	* apps/examples/nettest:  Update test so that it can be used to test
-	  IPv6 TCP sockets (2015-01-20).
-	* Many files: Correct name of fields in struct sockaddr_in6:  sin6_port
-	  and sin6_family, not sin_port and sin_family (2015-01-20).
-	* apps/netutils/telnetd:  Add protection when CONFIG_SCHED_HAVE_PARENT
-	  is enabled:  Call sigaction with SA_NOCLDWAIT so that exit status is
-	  not retained (no zombies) and block receipt of SIGCHLD so that accept
-	  is not awakened by a signal.  If accept() is awakened by a signal, do
-	  not do anything crazy like exit.  Most from Rony Xln (2015-01-22).
-	*  apps/examples/udp:  The UDP test example has been extend to support
-	  IPv6 domain sockets (2015-01-22).
-	* apps/nshlib:  Add the ping6 command to support checking IPv6 networks.
-	  (2015-01-23).
-	* apps/nsh: Clean up network status presentation for IPv6 (2015-01-24).

-7.8 2015-02-11 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/interpreters/micropython: Add math library defines for nan(),
-	  copysign(), and trunc() functions.  From Brennan Ashton (2015-01-26).
-	* apps/examples/ustream:  Add a simple test of Unix domain sockets
-	  (2015-01-27).
-	* apps/examples/udgram:  Add a simple test of Unix domain datagram
-	  sockets (2015-01-28)
-	* apps/Makefile and builtin/Makefile: Fix for building with parallel
-	  make. Build-server sometimes failed 'make -j24' with errors in the
-	  builtin line or or sometimes silently succeeds but generated builds
-	  that contain a random subset of configured NuttX applications. There
-	  are two root causes for this: (1) Recipes for building builtin_list.h
-	  and builtin_proto.h are not linearizable, and (2) Nothing ensures
-	  that 'make context' is run first for apps/builtin.  This change
-	  address both issues. From Juha Niskanen (2015-02-03).
-	* apps/netutils/netlib:  Add utilities to convert to/from prefix lengths
-	  from/to 128-bit network masks (2015-02-06).
-	* apps/nshlib: Modify the NSH IPv6 ifconfig command to show the more
-	  standard post-pended prefix value, rather than the full 128-bit netmask
-	  (2015-02-06).
-
-7.9 2015-04-14 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/ostest: Improved error checking for sem_timedwait()
-	  from Juha Niskanen (2015-02-20).
-	* apps/netutils/Kconfig, Make.defs, and pppd/: Add a PPP daemon.  From
-	  Max Neklyudov (2015-03-11).
-	* Rename arch_nshinitialize() to board_app_initialize() (2015-03-30).
-	* apps/nshlib:  NSH initialization now calls boardctl(BOARDIOC_INIT)
-	  instead of board_app_initaliaze().   Remove support for
-	  CONFIG_NSH_ARCHMAC.  It is not used and there are better ways to do
-	  that operation (2015-03-31).
-	* apps/examples/touchscreen:  No longer calls arch_tcinitialize() or
-	  arch_tcuninitialize().  Instead the new OS interface boardctl() is
-	  called to perform these test operations on the touchscreen driver
-	  (2015-03-31).
-	* apps/examples/adc: Change apps/examples/adc to that is now calls
-	  boardctl() instead of adc_devinit() in order to initialize the ADC
-	  device(2015-03-31).
-	* apps/examples/pwm/: Replace calls to pwm_devinit() in
-	  apps/examples/pwm with calls to boardctl() (2015-03-31).
-	* apps/examples/:  More renaming: up_lcdinitialize->board_lcd_initialize,
-	  up_lcdgetdev->board_lcd_getdev, up_lcduninitialize->board_lcd_uninitialize
-	  (2015-04-04).
-	* apps/examples/nxlines/: Add the new 'capped' parameter to nx_drawline()
-	  calls (2015-04-05).
-	* apps/modbus/tcp:  Fix some compile problems when TCP is enabled
-	  (2015-04-06).
-	* apps/system: Clean up Kconfig menus.  The way it worked before, it was
-	  difficult to see what was enabled and what was not.  menus replaced
-	  with menuconfig (2015-04-07).
-	* apps/examples/ostest/sigprocmask.c: Add a simple test of sigprocmask,
-	  sighold, and sigrelse (2015-04-09).
-	* apps/modbus: Includes extensions to support RTU master mode by
-	  Armink(383016632@qq.com):
-	  https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32.  Ported
-	  to NuttX by Darcy Gong.
-	* apps/nshlib:  Allow NSH 'date' command with no hardware RTC.  Thisi
-	  command is useful without an RTC too.  Also, this permits testing on
-	  the simulator which never has an RTC (2015-04-11).
-	* apps/netutils/ppp: Make pppd PAP authentication optional.  From
-	  Brennan Ashton
-	* apps/examples/pppd:  Add PPPD test case.  Split out from
-	  apps/netutils/pppd by Brennan Ashton.
-	* apps/netutils/pppd: Spit up pppd utils.  From Brennan Ashton.
-	* apps/system/zoneinfo:  All logic to build timezone info.  Does not do
-	  much else yet (2015-04-14).
-
-7.10 2015-06-09 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/system/zoneinfo:  Add logic to build a ROMFS file system
-	  containing the timezone data (2015-04-15).
-	* apps/nshlib/nsh_timcmds.c: Check return values from time functions
-	  (2015-04-15).
-	* apps/examples/nxlines:  Fix missing right bracket that causes
-	  compile error when CONFIG_NX_XYINPUT=y.  From Librae (2015-04-16).
-	* apps/examples: When boardctl() fails, need to print errno not the
-	  returned value which will always be -1 (2015-04-16).
-	* apps/examples: Correct use of the BOARDIOC_GRAPHICS_SETUP boardctl()
-	  call (2015-04-16).
-	* apps/examples/ltdc:  Add testing support for the STM32 LTDC's 2D
-	  DMA. From Marco Krahl (2015-04-16).
-	* apps/nshlib/: Fix handling of gmtime_r return value in time commands.
-	  gmtime_r returns a pointer, not an int (2015-04-21).
-	* apps/netutils/ntp: Fix mismatched sched_lock/unlock.  Noted by
-	  Juha Niskanen (2015-05-06).
-	* apps/examples:  Modify/simpify apps/examples build files.  From Roman
-	  Saveljev (2015-05-06).
-	* apps/nshlib/nsh_netinit.c and apps/examples/ustream/: Add poll
-	  support for Unix stream sockets.  From Jussi Kivilinna (2015-05-12).
-	* apps/examples/ostest: Add a test of nested signals.  There are no
-	  failures to handle signals but neither am I getting any nested
-	  signal handling (2015-05-12).
-	* apps/nshlib: Enhancements to NSH ifconfig for case of multi-link
-	  operation, TUN device and local connections.  From Max Neklyudov
-	  (2015-05-19).
-	* apps/nshlib: Enhanced output to NSH ping command from Max Neklyudov
-	  (2015-05-27).
-	* apps/examples/elf: Add configuration options to support building the
-	  hello++4 example that depends upon having uClibc++ available.  From
-	  Leo aloe3132 (2015-05-29).
-	* apps/platform/stm32f4discovery: Move up_cxxinitialize from
-	  nuttx/configs/stm32f4discovery/src to apps/platform/stm32f4discovery
-	  where it belongs (2015-05-29).
-	* apps/examples/elf/tests/helloxx: Add hello++5 to ELF example.  From
-	  Leo Aloe3132 (2015-06-01).
-	* apps/netutils/thttpd/ and apps/examples/thttpd/: Add support for using
-	  binfs/ instead of NXFLAT.  NXFLAT is probably the better solution but
-	  recently compiler changes make it unusable.  binfs or ELF are fallback
-	  binary formats.  This commit adds an option to use binfs (2015-06-02).
-	* apps/examples/unionfs: Add a test of the union file system to
-	  apps/examples (2015-06-05).
-	* apps/examples/thttpd now uses the Union File System if BINFS is
-	  selected for CGI binaries (2015-06-06).
-	* apps/nshlib/: The NSH mount command now recognizes the Union file
-	  system type when listing mounted file systems (2015-06-07).
-
-7.11 2015-08-13 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/netutils/thttpd:  Fix compilation problems when
-	  CONFIG_THTTPD_GENERATE_INDICES is defined (2015-06-12).
-	* apps/include: Clean up and review of header files for conformance to
-	  standards (2015-06-12).
-	* apps/examples/ostest/:  Extend the OS test to include a test of
-	  pthread_mutex_trylock() for recursive mutexes. From Juha Niskanen
-	  (2015-06-16).
-	* apps/netutils/thttpd: Missing gci-src as a dependency path when
-	  building with BINFS enabled (2015-06-18).
-	* The apps/ directory has been removed from the NuttX GIT repository
-	  and now stands alone in its own repository (2015-06-27).
-	* apps/examples/poll: Fix a few bit-rot compilation errors (2015-07-01).
-	* apps/nshlib: NSH will now support an (optional) shutdown command if
-	  the board provides the option CONFIG_BOARDCTL_POWEROFF.  The command can
-	  also be used to reset the system if CONFIG_BOARDCTL_RESET=y.
-	  (2015-07-04).
-	* apps/system/poweroff:  Remove the system poweroff command.  This is
-	  replaced with the NSH shutdown command (2015-07-02).
-	* apps/nshlib:  Add support for a uname command (2015-07-04).
-	* apps/system/sysinfo:  Remove the system sysinfo command.  This is
-	  replaced with the NSH uname command (2015-07-04).
-	* apps/system/netdb:  Add a command to access the network database
-	  (2015-07-08).
-	* apps/netutils/dnsclient and include/netutils/dnsclient.h:  Move the
-	  DNS client logic into the NuttX C library.  It is a necessary part
-	  for the full implementation of the netdb logic and provides more
-	  flexibility in that location (2015-07-10).
-	* apps/examples/ and apps/netutils: Remove calls to obsolete, non-
-	  functional DNS interfaces (2015-07-11).
-	* apps/netutils and apps/nshlib: Replace calls to the non-standard
-	  dns_gethotip with calls to standard gethostbyname (2015-07-11).
-	* apps/netutils/netlib and other files: Create netlib wrapper functions
-	  around dns_getserver() and dns_setserver() to isolate application
-	  code from changes to those interfaces (2015-07-12).
-	* apps/nshlib:  Add an nslookup command (2015-07-13).
-	* apps/examples/nxlines:  If CONFIG_NX_ANTIALIASING=y, then the nxlines
-	  example now erases a line that is 2 pixels longer and 2 pixels wideri
-	  than the line it drew.  That eliminates edges effects due to applying
-	  the anti-aliasing algorithm twice.  A better solution would be to makei
-	  anti-aliasing an option for each graphics call so you would rend the
-	  line with anti-aliasing ON and clear it with anti-aliasing OFF. but I
-	  don't have the wherewithal for that change today (2015-04-14)`.
-	* apps/nshlib and apps/examaples/thttpd:  Change decoding to handle the
-	  increased size of the scheduling policy field in the TCB (2015-07-23).
-	* apps/examples/ostest: Improve synchronization in round robin tests.
-	  On very fast processors, there are race conditions that make the test
-	  failure.  Need better interlocking to assure that the threads actually
-	  do start at the same time (2015-07-24).
-	* apps/examples/ostest: Add a test for the sporadic scheduler.  This
-	  test is failing as of this commit (2015-07-24).
-	* apps/system/readline:  Add support for Unix-style tab complete to
-	  readline.  This currently works only for built-in functions.
-	  Contributed by Nghia Ho (2015-07-28).
-	* apps/system/readline and apps/nshlib:  Extended the tab-completion
-	  support to also expand NSH command names (2015-07-30).
-	* apps/system/readline and apps/nshlib:  Add support for an in-memory
-	  command line history that can be retrieved using the up and down
-	  arrows.  Contributed by Nghia Ho (2015-08-09).
-	* apps/Makefile:  No longer depends on hardcoded lists of directories.
-	  Instead, it does a wildcard search to find all appropriate
-	  directories.  This means that to install a new application, you
-	  simply have to copy the directory (or link it) into the apps/
-	  directory.  If the new directory includes a Makefile and Make.defs
-	  file, then it will automatically be included in the build (2015-08-11).
-	* apps/Makefile, Kconfig, */Kconfig, tools/mkkconfig.sh: Add the tool
-	  mkkconfig.sh that dynamically builds the apps/Kconfig file at
-	  configuration time.  The hardcoded configuration file has been removed
-	  and now the top-level Makefile executes tools/mkkconfig.sh to auto-
-	  generate the top-level Kconfig file.  A new apps/ make target call
-	  preconfig: was added to support this operation.  Now you do not have
-	  to modify the top-level Kconfig file to add a new directory into the
-	  configuration; the top-level subdirectory simply needs to include a
-	  Kconfig file and it will automatically be included in the
-	  configuration.  The native Windows build is temporarily broken until
-	  a new apps/tools/mkconfig.bat script is generated (2015-08-11).
-	* apps/tools/mkkconfig.bat:  Add the Windows script corresponding to
-	  apps/tools/mkkconfig.sh.  Needed for a Windows native build.  Untested
-	  on initial commit (2015-08-12).

-7.12 2015-10-01 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/can:  Extend the CAN loopback test by adding more
-	  command line options (2015-08-17).
-	* apps/examples/usbserial: Can now be run as an NSH builtin-function.
-	  Now uses a configurable IO buffer size (2015-08-20).
-	* Various Kconfig files in netutils:  Fix some changes from from
-	  NETUTILS_DNSCLIENT to NETDB_DNSCLIENT.  From Pavel Pisa (2015-08-20).
-	* system/netdb:  Failed to build if CONFIG_NET_HOSTFILE was not defined
-	  because gethostbyaddr() was not available.  Noted by OrbitalFox
-	  (2015-08-21).
-	* apps/system/symtab: Optional canned symtab inclusion to the build. When
-	  option CONFIG_SYSTEM_SYMTAB is selected and symbol table file
-	  libc/symtab/canned_symtab.inc is prepared then application can
-	  use system provided complete symbol table. The option has
-	  substantial effect on system image size. Mainly code/text. If
-	  loading of applications at runtime is not planned do not select
-	  this.  From Pavel Pisa (2015-08-23).
-	* apps/examples/nettest: Add option to suppress network initialization.
-	  This is necessary if the nettest is run from NSH which has already
-	  initialized the network (2015-08-26).
-	* apps/examples/nettest: Extend test so that can be performed using the
-	  local loopback device (2015-08-26).
-	* apps/nshlib: Fix error handling in 'cat' command.  On a failure to
-	  allocate memory, a file was not being closed.  From Bruno Herrera
-	  (2015-08-26).
-	* apps/nshlib: Fix error handling in 'mv' command.  On a failure to
-	  expand the second path, the memory allocated for the expansion of the
-	  first path was not being freed.  From Bruno Herrera (2015-08-26).
-	* apps/examples/netloop:  Add a test of the local loopback device
-	  (2015-09-02).
-	* apps/modbus and apps/include/modbus:  Macros PR_BEGIN_EXTERN_C and
-	  PR_END_EXTERN_C were not defined in all contexts.  Replace with
-	  explicit expansion in all cases. From Stefan Kolb (2015-09-03).
-	* apps/canutils/uavcan: Add support for libuavcan.  From  Paul
-	  Alexander Patience (2015-09-25).
-	* apps/examples/udpblaster: Add a test to stress the network by
-	  sending UDP packets at a very high rate.  (2015-09-30).
-	* apps/examples/uavcan: libuavcan example from Paul Alexander
-	  Patience (2015-10-01).
-
-7.13 2015-12-05 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/examples/fstest:  Add a generic file system test.  This is
-	  essentially the same as examples/smart, but has all of the SmartFS
-	  specific logic ripped out.  This was created for testing the new
-	  tmpfs (2015-10-10).
-	* apps/examples/zerocross: Add a Zero Cross application example.
-	  From Alan Carvalho de Assis (2015-10-13).
-	* apps/examples/media:  Add a simple test for access of media via
-	  a block driver or MTD driver (2015-11-09).
-	* apps/nshlib/nsh_ddcmd.c:  Now that NuttX automatically converts
-	  block devices to character devices, all of the BCH stuff in NSH
-	  can be removed (2015-11-21).
-	* apps/system/hexed:  Port the hexed command line hexadeciamal
-	  editor to Nuttx.  See http://apps.venomdev.net/hexed/.
-	  Initial port is not functional (2015-11-21).
-	* apps/fsutils/smartfs: Move into apps/fsutils from kernel, now
-	  uses only open and ioctl.  From Ken Pettit (2015-11-23).
-	* apps/fsutils/smartfs/ and apps/nshlib/: Add configuration option
-	  to supported multiple root directories. From Ken Pettit (2015-11-23).
-	* apps/nshlib:  Add support for 'basename' and 'dirname' commands
-	  (2015-11-23).
-	* apps/nshlib:  Like bash, NSH set command should strip off any
-	  leading or trailing whitespace (2015-11-23).
-	* apps/nshlib: The mount commands now accepts mount options (currently
-	  needed only for the hostfs file system).  From Ken Pettit (2015-11-25).
-	* apps/nshlib:  NSH no longer calls losetup() and loteardown directly.
-	  Now it opens /dev/loop and accomplishes these things using ioctl()
-	  calls (2015-11-25).
-	* apps/nshlib:  If CONFIG_NETDEV_STATISTICS=y, then print the network
-	  driver statistics in the ifconfig (15-11-26).
-	* apps/nshlib:  The 'ifconfig' command now uses /proc/net/<dev> to view
-	  network device configuration and status and /proc/net/stat to show
-	  network statistics.  A consequence of this is that you cannot view
-	  this network information if the procfs is not enabled and mounted at
-	  /proc (2015-11-27).
-	* apps/nshlib:  Remove all references to internal OS interface
-	  netdev_foreach().  Logic in ifconfig, ifup, and ifown now use the
-	  procfs file system to examine networking status.  (2015-11-27).
-	* apps/nshlib:  Add a new NSH losmart command.  losmart setups up
-	  a loop device for the smart MTD driver similar to losetup but
-	  with different syntax.  From Ken Pettit (2015-11-28).
-	* apps/nshlib:  The I/O buffer, g_iobuffer, should not be a global
-	  buffer.  That will not work in an environment where there are multiple
-	  NSH sessions.  The I/O buffer must, instead, be a part part of the
-	  session-specific data defined in nsh_console.h (2015-11-28).
-	* apps/nshlib:  The 'ps' command now uses /proc/<pid>/ to obtain
-	  task status information.  A consequence of this is that you cannot use
-	  the 'ps' command if the procfs is not enabled and mounted at
-	  /proc (2015-11-28).

-7.14 2016-xx-xx Gregory Nutt <gnutt@nuttx.org>
-
-	* netutils/telnetd:  Move the Telnet driver from netutils/telnetd to
-	  nuttx/drivers/net.  It is a driver an belongs in the OS.  There are
-	  still some partitioning issues with the interface to the Telnet
-	  driver (2015-12-07).
-	* netutils/telnetd:  No longer calls OS interface telnet_driver.  Now
-	  creates Telnet sessions by opening a new factory device at /dev/telnet
-	  and then using ioctl calls to create the session character drivers
-	  at /dev/telnetN (2015-12-07).
-	* netutils/ping: Unfinished implementation of ping/ping6 using raw
-	  sockets (2015-12-11).
-	* examples/module:  Add a test harness for verifying NuttX kernel
-	  modules (2015-12-12).
-	* apps/nshlib:  Add module commands: insmod, rmmod, and lsmod
-	  (2015-12-13).
-	* apps/examples/pca9635:  Add a simple test of PCA9635PW PWM LED
-	  driver.  From Alan Carvalho de Assis (2015-12-15).
-	* apps/examples/ostest:  Add a test of POSIX timers using
-	  SIGEV_THREAD (2015-12-30).
-	* apps/nshlib:  Add a 'time' command that may be used to time the
-	  execution of other commands (2015-12-31).
-	* apps/netutils/netlib:  Add netlib_get_dripv4addr() and
-	  netlib_get_ipv4netmask().  From Pelle Windestam (2016-01-14).
-	* apps/fsutils/passwd: Utility library for accessing a password
-	  file like /etc/passwd (2016-01-19).
-	* apps/nshlib/nsh_passwdcmds.c:  Add useradd, userdel, and passwd
-	  commands (2016-01-20).
-	* apps/nshlib:  Now supports a Message of the Day (MOTD) that will
-	  be presented after the NSH greeting (2015-01-20).
-	* apps/nshlib:  All sessions may be protected with logins using
-	  the encrypted password in /etc/passwd (2016-01-20).
-	* apps/fsutils/inifile:  Move system/inifile to fsutils/inifile
-	  where it seems to fit in better (2016-01-20).
-	* apps/nshlib: Extend logins.  Added: Optional platform-specific
-	  function to perform password verification and optional delay
-	  after each failed login attempt (2016-01-22).
-	* system/ramtron:  Removed completely.  It inappropriately used
-	  an internal OS interface (up_spiinitialize), that has been
-	  obsoleted.  That's what happens when you violate interface
-	  boundaries between the application and the OS (2016-01-27).
-	* apps/platform/Makefile:  Use a relative path to the board
-	  directory link rather than the absolute path.  For Cygwin, the
-	  absolute would would need converted with cygpath.  But just using
-	  the relative path is a simpler solution (2016-01-27).

-	* apps/examples/ubloxmodem:  app to control the power state of the
-	  modem in nsh.  From  Vladimir Komendantskiy (2016-01-31).
-	* apps/system/ubloxmodem:  Moved the modem application from
-	  examples/ to system/ (2016-01-31).
-	* apps/system/i2c:  The I2C tool now obeys it OS interfacing:
-	  it now uses an I2C character driver to access the I2C bus

-	  (2016-06-27).
-	* apps/nshlib: 'ps' command now prints out the stack usage if stack
-	  coloration is enabled.  From Frank Benkert (2016-06-30).
-	* All inclusion of apps/ header files were removed from the nuttx/
-	  repository. This caused a lot of reshuffling of logic:  binfmt pcode
-	  support, usbmonitor is now a kernel thread, TZ/Olson database moved to
-	  libc/zoneinfo (2016-06-29).
-	* apps/include directory structure reorganized.  There are no longer any
-	  header files in the apps/include/. directory.  Rather, sub-directories
-	  were added to match the partitioning of apps/ sub-directories and the

-	* apps/nshlib/nsh_proccmds.c:  Recent enhancements to cmd_ps trips a
-	  floating point exception if LIBC_FLOATINGPOINT is not defined (at
-	  least on Cortex M4 w/ hardfloat).  I�m using a buildroot gcc
-	  configured to support Cortex-M4F and the hard float ABI, target files
-	  are compiles with: -mcpu=cortex-m4 -mthumb -mfpu=fpv4-sp-d16
-	  -mfloat-abi=hard.  I�m not sure the best way to address this, but the
-	  this change is the first that comes to mind.  Note, I added the float
-	  qualifier �F� after a few constants to prevent the compiler from
-	  promoting the multiplication and division to double (expensive on
-	  M4F) then demoting to single float for the store.  From David
-	  Alessio (2016-07-10).
-	* Call all includes fronm <apps/bla/bla.h> to "bla/bla.h". From

-	* apps/netutils/esp8266: In Kconfig, select ARCH_HAVE_NET when
-	  NETUTILS_ESP8266 is selected.  This allows, among other things,
-	  support for network debug output.  From Pierre-noel Bouteville
-	  (2016-07-14).
-	* apps/nshlib: PS Command: When Priority Inheritance is enabled, the
-	  format of /proc/<PID>/status changes to show both the current priority
-	  and the thread�s base priority.  This messes up the format of cmd_ps.
-	  From David Alessio (2016-07-15).
-	* apps/examples/pty_test: PTY test program.  From Alan Carvalho de Assis
-	  (2016-07-15).
-	* apps/examples/media: media example was intended to take either a
-	  command line argument, or a compiled-in default value from config.
-	  However, the default was ignored, leading to confusing error messages.
-	  From ziggurat29 (2016-07-17).

-	  script, the settings are returned to the default settings when it
-	  exits.  Included child scripts will run with the parents settings and
-	  changes made in the child script will effect the parent on return.
-	  Use 'set -e' to enable and 'set +e' to disable (ignore) the exit
-	  condition on commands. The default is -e. Errors cause script to
-	  exit.  Use 'set -x' to enable and 'set +x' to disable (silence)
-	  printing a trace of the script commands as they are ececuted. The
-	  default is +x. No printing of a trace of script commands as they are
-	  executed.  From David Sidrane (2017-04-05).
-	* Print expanded variables if -x.  From David Sidrane (2017-04-05).
-	* examples/udpblaster:  Several fixes to work with 6LoWPAN (2017-04-06).
-	* examples/udpblaster:  Add logic to bind the local UDP socket to a

-	  changes in configuration variable usage (2017-04-08).
-	* NSH set command:  Eliminate useless argc check of SCRIPTS are enabled
-	  but ENVIRONMENT is disabled (2017-04-09).
-	* examples/ostest: additional test for rwlock and one for cancel
-	  cleanup handlers.  From Juha Niskanen (2017-04-10).
-	* wireless/wapi:  Quick port of Wapi wireless services.  No build
-	  support yet.  This also depends on features not supported by NuttX.
-	  This is a work in progress (2017-04-10).
-	* wireless/wapi:  Remove logic that depends on Linux netlink.  Add
-	  (untested) build support (2017-04-10).
-	* wireless/wapi:  Remove functionality that depends on the Linux

-	  concept to wapi.  From Anthony Merlino (2017-04-20).
-	* ieee802154: Move non-radio files from libradio to libutils.  Add
-	  ieee802154_getpanid() (2017-04-21).
-	* wireless/ieee802154:  Beginning of support for IEEE 802.15.4 MAC
-	  library (2017-04-21).
-	* wireless/ieee802154/libmac:  Finishes all defined MAC IOCTL helpers
-	  (there are a few that are not defined) (2017-04-21).
-	* netlib: Get and/or set PAN ID of IEEE 802.15.4 radio (2017-04-21).
-	* wireless/ieee802154: libaudio and libmac need to return the correct
-	  error codes (2017-04-22).
-	* nshlib: nsh_netcmds.c should include netlib.h even if neither TCP nor
-	  UDP are enabled (2017-04-25).
-	* apps/wireless/wapi:  Correct an error in dependency generation
-	  (2017-04-25).
-	* examples: random: avoid stack overflows.  From Juha Niskanen
-	  (2017-04-26).
-	* wireless/wapi: Improve error reporting IOCTL failures (2017-04-26).
-	* I need to look at the registers that are at or around 0xe000ef90.
-	  Using mw and xd, I see that nsh does not support pointers greater
-	  than 0x7fffffff.  A quick look at the source shows that the pointers
-	  for those two commands are set with calls to strtol() rather than
-	  strtoul().  Changing the two pointer-setting instances to strtoul()
-	  fixes the problem, at least for my architecture/config.  From Ian
-	  McAfee (2017-04-26).
-	* NSH: Needs to include tftp.h if TFTP not disabled (2017-04-29).
-	* netutils/dhcpc:  Make the network device name a configuration
-	  option.  Was hardcoded to eth0 but may, instead, need to be wlan0
-	  (2017-05-02).
-	* nshlib/nsh_netinit.c: If IEEE802.11 selected use wlan0 instead of
-	  eth0 for network device name (2017-05-02).
-	* wireless/wext:  Add drivers_wext from the WPA supplicant; Integrate
-	  into NSH.  From Simon Piriou (2017-05-02).
-	* 6LoWPAN: Replace some rime address naming with more consistent
-	  short/extended address terminology (2017-05-04).
-	* wireless/ieee802154:  Removes libradio to coincide with removal of
-	  ioctl with radio. Moves all functionality from libradio to libmac.
-	  From Anthony Merlino (2017-05-05).
-	* wireless/wapi: wpa_driver_wext_associate() now accepts a
-	  configuration parameter that can be used to specify the wireless
-	  properties (2017-05-06).
-	* nshlib:  NSH now has configuration options to select the
-	  wireless properties.  It builds the configuration structure and
-	  passes this to wpa_driver_wext_associate() so that it will set the
-	  network as configured (2017-05-06).
-	* Add platform files for nucleo-l452re and nucleo-l496zg.  From Juha
-	  Niskanen (2017-05-08).
-	* wireless/ieee802154:  Adds rxonidle attribute helpers.  From Anthony
-	  Merlino (2017-05-08).
-	* wireless/ieee802154:  Adds sniffer functionality back in to I8SAK
-	  app.  From Anthony Merlino (2017-05-08).
-	* NSH wireless setup:  Move call to nsh_associate().  It should be
-	  possible to associate with an AP when DHCPC is disabled (2017-05-09).
-	* Fix some calls to task_create():  argv[0] is the first parameter, not
-	  the name of the task (2017-05-09).
-	* wireless/ieee802154: Restructures i8sak app and adds blaster
-	  functionality.  From Anthony Merlino (2017-05-09).
-	* examples/configdata: add stacksize and priority.  From Juha Niskanen
-	  (2017-05-10).
-	* Bitbucket Issue 5:  I found an unexpected behavior in apps/
-	  configuration generation. Adding external symbolic link in apps/
-	  directory and using Make.defs for Kconfig generation, Kconfig file
-	  has a wrong path in the source argument. It contains original dir
-	  path outside of the source tree instead path to sub-directory in
-	  apps/.  The problem is connected with make/system symbolic link path
-	  resolution.  Corrected by a patch submitted by Artur Madrzak with
-	  Issue 5 (2017-05-11).
-	* Bitbucket Issue 5, apps build system: The previous patch wasn't
-	  complete, it was just idea how to resolve issue.  Please, find
-	  attached issue5.patch to resolve it. It can be applied on top current
-	  apps/master. From Artur Madrzak (2017-05-12).
-	* Fix the new can.h header location.  From Alan Carvalho de Assis
-	  (2017-05-12).

-	  only GNU C++ initialization function.  Remove all other C++
-	  initialization functions (2017-05-13).
-	* Move up_cxxinitialize() prototype from nuttx/include/nuttx/arch.h to
-	  apps/include/platform/cxxinitialize.h (2017-05-13).
-	* apps/examples/nettest: Fix an error in pre-processor expression
-	  (2017-05-13).
-	* wireless/ieee802154: i8sak adds event handling from MAC char driver.
-	  From Anthony Merlino (2017-05-16).
-	* apps/examples/mtdpart: Prevent part array overflow.  mtdpart examples
-	  create partitions and allocate from 1 index not a 0 index to part[]
-	  array. This cause buffer overflow for part array.  This change fixes
-	  this problem.  From  EunBong Song (2017-05-17).
-	* apps/examples/can:  Fix can example app to print data when
-	  CONFIG_EXAMPLES_CAN_READ is defined.  From Alan Carvalho de Assis
-	  (2017-05-17).
-	* apps/: Make more globals static to avoid name clashes.  From Juha
-	  Niskanen (2017-05-19).
-	* Ensure netlib will not be broken when setip will not bring the
-	  network up anymore.  From Sebastien Lorquet (2017-05-19).
-	* DHCPC: Remove hard-coded interface device.  Now passed as a parameter
-	  to dhcpc_open().  From Sebastien Lorquet (2017-05-19).
-	* nshlib: Fix a resource leak in cmd_hexdump().  From Nobutaka
-	  Toyoshima (2017-05-22).
-	* wapi: add basic wapi_event_stream_extract implementation.  From Simon
-	  Piriou (2017-05-21).
-	* apps/system/dhcpc:  Add a command to renew or establish a lease on an
-	  IPv4 address (2017-05-21).
-	* apps/system/ntpc:  Add a command to start or stop the NTPC daemon
-	  (2017-05-21).
-	* apps/system/dhcpc: Add missing argument of fprintf (2017-05-21).
-	* apps/nshlib:  Add a new option CONFIG_NSH_NETLOCAL that will suppress
-	  some built in operations and will support manual configuration of a
-	  wireless network (2017-05-21).
-	* apps/system/ramtest: Make stacksize and priority conigurable
-	  (2017-05-22).
-	* The dedicated windows tool at tools/mkkconfig.bat uses $APPSDIR,
-	  which is not a windows shell variable, and is left uninitialized, but
-	  in fact should be the current directory.  From Sebastien Lorquet
-	  (2017-05-22).

-	* apps/system/composite: Update to apps/system/composite associated with
-	  big changes to the composite device logic.  From Frank Benkert
-	  (2017-06-01).
-	* wireless/ieee802154: Modifies i8 to support running various routines.
-	  From Anthony Merlino (2017-06-14).
-	* wireless/ieee802154: Rewrites i8sak to be test CLI for IEEE 802.15.4
-	  MAC layer.  From Anthony Merlino (2017-06-14).
-	* NSH network initialization: Fix some ieee 802.15.4 initialization
-	  logic.  It should not set the saddr or panid; those cannot be
-	  hard-coded but must come from the coordinator.  Re-factor a function
-	  that has gotten too big and too complex.  Do not set the IP address
-	  for 6loWPAN.  The 6loWPAN stack uses IP address that derive from the
-	  ieee 802.15.4 addressing and cannot be (safely) configured by the
-	  user (2017-06-17).
-	* i8sak:  Missing newline in fprintf output (2017-06-18).
-	* correct copy-paste typo in comments in composite_main.c  From Oleg
-	  Evseev (2017-06-18).
-	* Switches IEEE 802.15.4 based code to using byte arrays instead of
-	  uint16_t values for short address and PAN ID.  From Anthony Merlino
-	  (2017-06-19).
-	* fix copy-paste typo in nsh_usbconsole.c.  From Oleg Evseev
-	  (2017-06-19).
-	* examples/udp: Add configurable network device name; Add option to
-	  suppress network initialization which is not needed if started by NSH
-	  or for 6LoWPAN (2017-06-19).
-	* nshlib: fix size of 6LoWPAN extended address (2017-06-18).
-	* examples/udp:  Fix registration as a built-in program; Change some
-	  naming to make room for a second target.  Current one endpoint is the
-	  target and one is the host.  This will (eventually) allow two targets
-	  to be both endpoints of the test.  Change build so that both server
-	  and client can be on a target, rather than one on the target one on
-	  the host PC.  Server IP address may not be provided on the command
-	  line (2017-06-19).
-	* examples/smart: Fix some compilation errors.  Obviously this test has
-	  not been used in a LONG time (2017-06-20).
-	* examples/udp:  Port numbers need to be configurable to work with
-	  6LoWPAN.  Need to bind the client socket to a port number.  This was
-	  not required before so is a apparently a change in the UDP packet
-	  dispatch logic (2017-06-20).
-	* ieee802154: Changes to support beacon-enabled networks.  From Anthony
-	  Merlino (2017-06-21).
-	* wireless/ieee802154: Adds option to make it easy to send large frame
-	  for testing purposes.  From Anthony Merlino (2017-06-21).
-	* examples/udp:  Renaming some files to prevent name collision in
-	  libapps.a.  Fix naming of a configuration setting (2017-06-23).
-	* examples/nettest:  Renaming some files to prevent name collision in
-	  libapps.a and to prepare to support target boards on both ends of the
-	  test.  Separate out network initialization so that it may,
-	  eventually, be used by both a target server and a target client.  Fix
-	  client/server naming confusion; add command line option to select the
-	  server address on the target.  Add support for both endpoints on
-	  target boards vs. one on a target and one on the host PC
-	  (2017-06-23).
-	* system/dhcpc:  The DHCPC renew command did not build correctly due to
-	  naming problems.  Noted by Masayuki Ishikawa (2017-06-23).
-	* examples/nettest: Fixes for building with loopback device again after
-	  the last changes (2017-06-23).
-	* examples/nettest:  The send buffer size is now a configuration option
-	  (2017-06-24).
-	* examples/udp and examples/nettest: Fix some naming collisions;
-	  examples/nettest:  Fix some build issues with two targets
-	  (2017-06-25).
-	* ieee802154: Adds scan command.   From Anthony Merlino (2017-06-25).
-	* ieee802154: Minor fix to setup logic for i8sak.  From Anthony Merlino
-	  (2017-06-25).
-	* ieee802154: start of scan/beacon-enabled network.  From Anthony
-	  Merlino (2017-06-26).
-	* netutils/telnetc:  This a port of libtelnet to NuttX (2017-06-26).
-	* system/telnet:  Add Telnet Chat daemon and and client from libtelent
-	  (2017-06-26).
-	* NSH library:  Add a Telnetd command.  This is needed when network
-	  initialization is deferred.  In that case, telnet daemon cannot be
-	  started until the network is finally initialized.  The telnetd
-	  command was added just for that case:  So that the telnet daemon can
-	  be started from the NSH command line after the network is configured
-	  (2017-06-26).
-	* revise some of the state handling in the previous commit
-	  (2017-06-26).
-	* system/telnet: POLL must not be disabled in configuration.  Telnet
-	  client port argument is no optional (2017-06-27).
-	* netutils/telnetd and users of telnetd:  Add support for IPv6
-	  (2017-06-27).
-	* ieee802154/i8sak: Adds coordinfo command allowing you to poll various
-	  attributes related to the coordinator.  From Anthony Merlino
-	  (2017-06-27).
-	* i8sak:  Need to increment the next_saddr after each successful
-	  association (2017-06-29).
-	* i8sak:  Add a option to retry on failures to the assoc command
-	  (2017-06-29).
-	* apps/examples/thttpd:  Remove the netstats demo.  This depends on an
-	  illegal function call and cannot be supported.  That example could be
-	  replaced with logic that uses the procfs network entries as was done
-	  for NSH which had the same issue.  But I am too lazy to implement
-	  that (2017-07-01).
-	* i8sak: Adds reset command to reset the MAC layer.  Adds option to
-	  assoc command -t to specify how long to wait for a response from the
-	  Coordinator.  From Anthony Merlino (2017-07-01).
-	* Eliminate a warning when both Ethernet and 6LoWPAN are enabled;
-	  improve some naming (2017-05-02).
-	* ieee802154: Adds reset command, adds resp_waittime option to
-	  associate, and a few other minor tweaks.  From Anthony
-	  Merlino(2017-07-02).
-	* NSH library: Fix build break in nsh_command.c with IPv4/IPv6 dual
-	  stack.  From Masayuki Ishikawa (2017-07-04).
-	* apps/examples/keypadtest: REMOVED and warehoused in the Obsoleted
-	  repository.  This was just a bad clone of apps/examples/hidkbd for a
-	  keypad driver that was removed years ago.  It also uses illegal
-	  function calls into the OS.  So it has no purpose:  It is
-	  redundant, it uses illegal interfaces, and is a test for non-existent
-	  code (2017-07-04).
-	* tools/mkkconfig.bat: Use %cd% instead of %~dp0 for usage of APPSDIR
-	  in this batch file (2017-07-05).
-	* system/dhcpc: Fix warning about renew_main.o appear twice in rule
-	  (2017-07-05).
-	* tools/mkkconfig.bat:  Remove quotes in echo.  These were begin
-	  Echo'ed and generating double quots in the output.  From Jeff
-	  (2017-07-05).
-	* Windows build fixes:  tools/mkkconfig.bat - switch APPSDIR path to
-	  use forward slashes for kconfig-frontends. interpreters/ficl -
-	  Reorder some targets that causes GNUwin32 make to behave badly.  From
-	  Jeff (2017-07-06).
-	* platform/Makefile: More attempts to fix for Windows native build.
-	  Backslash as a delimiter causes problems in pattern subsitutions
-	  (2017-07-06).
-	* apps/examples/ipforward: Add beginning of an IP forwarding example
-	  using only TUN devices.  Test extended to test forwarding of ICMPv6
-	  multicast messages.  Completes code for apps/examples/ipforward.
-	  Still untested (2017-07-09).
-	* apps/netutils/tftpc: Missing header file causes errors in some
-	  configurations (2017-07-10).
-	* Socket I/F: Cleanup for good CONFIG_NET_PKT build (2017-07-14).
-	* netutils/netlib:  Fixes to work when only USRSOCK is enabled
-	  (2017-07-14).
-	* apps/system/composite:  Remove CDC/ACM and MSC configuration logic.
-	  This belongs in the OS composite initialization.  Add and argument so
-	  that you can select the USB composite configuration to be attached.
-	  Restore USB tracing; remove unused field in a structure.  Remove
-	  configuration settings that are no longer used.  Fix configuration
-	  selecting.. was setting the port number, not the configure ID.  Also
-	  add a configuration option to select the default configuration
-	  (2017-07-15).
-	* apps/system/composite: Add a configuration option to the boardctl()
-	  calls to support multiple composite device configurations dynamically
-	  (2017-07-16).
-	* i8sak: Minor formatting fix.  From Anthony Merlino (2017-07-10).
-	* wireless/ieee802154/i8sak: Minor setting changes.  From Anthony
-	  Merlino (2017-07-17).
-	* ieee802154/i8sak:  Adds command to trigger regdump of radio.  From
-	  Anthony Merlino (2017-07-18).
-	* apps/system/composite:  Remove references to USBMSC.  There still
-	  dependencies on CDC/ACM in the serial USB trace output.  That really
-	  should be removed (2017-08-21).
-	* netutils/ftpc:  Fix some memory leaks.  From Boris Astardzhiev
-	  (2017-07-27).
-	* Implement powermonitor example for ltc4151 current and voltage
-	  monitor.  From Giorgio Gro� (2017-07-28).
-	* NSH: Misc changes needed for PktRadio support (2017-07-30).
-	* examples/nettest/:  Loopback option should be available in Kconfig
-	  for PktRadio (2017-08-01).
-	* apps/netutils/netlib:  Add support for PktRadio IOCTL commands
-	  (2017-08-02).
-	* NSH library: Extend ifconfig command so that it can set variable
-	  length packet radio address (2017-08-02).
-	* netutils/netlib: Fix netlib_nodaddrconv() so that its return type is
-	  the same as other address conversion functions.  NSH: Correct parsing
-	  of ifconfig so that you can specify the HW address without specifying
-	  the IP address (2017-08-02).
-	* apps/examples/udp:  Enable testing with the broadcast address
-	  (2017-08-08).
-	* Remove references to obsoleted CONFIG_NETDEV_MULTINIC and
-	  CONFIG_NETDEV_MULILINK (2017-08-08).
-	* NSH library:  Update addroute and delroute command.  The would
-	  support either IPv4 or IPv6, but not both.  Allow expression of the
-	  netmask in IPv4 CIDR or IPv6 slash notation.  This really reduces the
-	  pain of using the commands, especially for IPv6 (2017-08-10).
-	* NSH Library: Add a route command that will dump the content of
-	  routing table (2017-08-11).
-	* apps/netutils/tftpc depends on CONFIG_NET_IPv4 (2017-08-12).
-	* Application.mk:  Add the .PRECIOUS target to prevent libapps.a from
-	  being deleted when the make is interrupted (2017-08-12).
-	* apps/examples/nximage: Remove unused global variable (2017-08-12).
-	* netutils/thttpd: Fix a malformed if condition detected by GCC 6.x.x
-	  (2017-08-12).
-	* All Makefiles:  Add .PRECIOUS: apps/libapps.a to every Makefile.
-	  Hopefully this will end awkward problems when you Control-C out of a
-	  build and libapps.a is deleted (2017-08-13).
-	* The last change added .PRECIOUS: $(BIN) to everyway Makefile in hopes
-	  the libapps.a will not be deleted on Control-C (unproven so far).
-	  However, $(BIN) may contain back slashes in some build platforms and
-	  that causes problems for make:  It can't handle the backslashes in
-	  the .PRECIOUS dependency list.  $(BIN) replaced with ../../libapp.a,
-	  where the number of ../ depends on the depth of the Makefile in the
-	  apps/ source tree (2017-08-13).
-	* netutils/netlib: Add a helper to decode short addresses
-	  (2017-08-18).
-	* apps/examples/pf_ieee802154:  Add for testing PF_IEEE802154 sockets.
-	  Add PANID to command line options; Cannot bind to address zero...
-	  There is no counterpart to INADDR_ANY for these radios (not now at
-	  least) (2017-08-19).
-	* Changes to netlib and nsh so that you build build with PF_IEEE802154
-	  enabled and 6LoWPAN disabled (2017-08-20).
-	* netutils/netlib: If only PF_IEEE802154 socket family is enabled, then
-	  must use SOCK_DGRAM (2017-08-21).
-	* NSH:  Add conditions so that ifconfig and ifup will not be disabled
-	  if we are using only PF_IEEE802154 (2017-08-21).
-	* dhcpd: Prevent buffer overflow in dhcpd_addoption.  offset represents
-	  distance from start of option buffer.  So this should be changed
-	  current option pointer minus start of buffer.  From EunBong Song
-	  (2017-08-25).
-	* apps/examples/nsh: Remove APPNAME, PRIORITY, and STACKSIZE settings
-	  from Makefile to avoid showing nsh in Builtin Apps.  From Masayuki
-	  Ishikawa (2017-08-26).
-	* examples: add DAC example.  From Juha Niskanen (2017-09-1).

-	* examples/ostest: sem_open() now returns SEM_FAILED in the event of a
-	  failure (2017-09-08).
-	* examples/adc: Fix g_adcstate.count initialization.  From Masayuki
-	  Ishikawa (2017-09-11).
-	* examples/fb:  Flesh out the framebuffer driver test.  examples/fb:
-	  Add a simple test for the framebuffer character driver.  This initial
-	  commit just verfies some interfaces and initialization logic.  Still
-	  need to add to graphics update logic (2017-09-12).
-	* Rename CONFIG_AUDIO_DEVICES to CONFIG_DRIVERS_AUDIO to conform better
-	  to the evolving configuration naming standard (2017-09-12).
-	* examples/fb:  Extend test to include 1-bpp monochrome (2017-09-13).
-	* Added a simple reader example for the LIS3DSH acceleration sensor on
-	  STM32F4Discovery.  From Florian Olbrich (2017-09-14).
-	* wireless/ieee802154/i8sak: Adds socket interface support. You can now
-	  use both socket or char driver to control the MAC layer.  From Anthony
-	  Merlino (2017-09-15).
-	* wireless/ieee802154/i8sak:  Fixes several bugs.  Adds sniffer port
-	  option and a few other get/set parameters.  From Anthony Merlino
-	  (2017-09-15).
-	* i8sak: Updates README to include details about socket interface and
-	  new addressing setup and fixes warning.  Fix warning about
-	  uninitialized variable.  From Anthony Merlino (2017-09-15).
-	* apps/examples/apa102: Add a Rainbow example for APA102 LED Strip.
-	  From Alan Carvalho de Assis (2017-09-18).
-	* netutils/netlib:  Add netlib_ipv6adaptor() and netlib_ipv4adaptor()
-	  (2017-09-19).
-	* netlib_ipv[4|6]adaptor: Add a check to handle the case where the
-	  network device configuration changed asynchronously and the second IOCTL
-	  returns more data than the allocated buffer (2017-09-20).
-	* apps/netutils/netlib:  Add helpers for reading the routing table:
-	  netlib_read_ipv4route() and netlib_read_ipv6route() (2017-09-20).
-	* apps/netutils/netlib:  Add new utilities netlib_ipv[4|6]router() that
-	  can be used to determine the IP address of a router that would be used
-	  some some destination IP address that is not locally accessible
-	  (2017-09-20).
-	* apps/netutils/netlib:  netlib_ipv[4|6]adaptor() will now use the new
-	  routing table interfaces if they are available:  If the destination IP
-	  address does not correspond to the network served by any device, then
-	  the address of the router that should get us to the correct sub-net is
-	  is determined.  Then the network adaptor that can communicate with the
-	  that router has the IP address that will returned (2017-09-20).
-	* apps/examples/flowc:  Add a simple test of serial hardware flow control
-	  (2017-09-23).
-	* apps/examples/qencode: The QENCODER name was changed to
-	  SENSORS_QENCODER fix it here.  From Alan Carvalho de Assis (2017-09-24).
-	* nshlib/nsh_parse.c: Avoid truncating the strcmp result into a unsigned
-	  char variable.  nshlib/nsh_netcmds.c: Check for valid hostip before
-	  using it.  nshlib/nsh_ddcmd.c: Fix resource leak when 'if=' or 'of='
-	  params are repeated in the command line.  For example:
-	    - dd if=/dev/null if=/dev/zero of=/dev/null or
-	    - dd if=/dev/zero of=/dev/zero of=/dev/null
-	  From Bruno Herrera (2017-09-25).
-	* nshlib/nsh_netcmds.c: Fix a compilation error when IPv4/IPv6 dual
-	  stack is enabled.  From Masayuki Ishikawa (2017-09-26).
-	* apps/examples/flowc:  Add a delay between received packets in order to
-	  force input flow control (2017-09-26).
-	* apps/examples/flowc: Fix some errors in receiver's verificationg
-	  logic.  Add a 'canned' data file so that we don't need to deal with the
-	  sender program; we can just 'cat' the canned data file (2017-09-26).
-	* apps/examples/flowc:  Add some syslog output to flush the syslog
-	  interrupt buffer (2017-09-27).
-	* apps/examples/flowc: Small improvement to break line if more than 80 .
-	  were printed.  From Alan Carvalho de Assis (2017-09-27).
-	* apps/examples:  In elf and nxflat examples, remove low-level
-	  interfaces and replace with call to exec() (2017-10-02).
-	* examples/elf and nxff: Won't build with CONFIG_BUILD_KERNEL because
-	  the interface exec() is not available in that configuration.  Also,
-	  remove a stray comma and a stray semacolon in examples/pty_test/Kconfig
-	  and examples/random/Kconfig (2017-10-06).
-	* Add powerled driver example.  From Mateusz Szafoni (2017-10-08).
-	* examples/ostest:  Works around a bug in printf() when cancellation
-	  points are enabled.  printf() is a cancellation point because it calls
-	  write().  This is correct according to OpenGroup.org.  However, printf
-	  holds the stdio library semaphore when it is canceled and this leaves
-	  the semaphore in a bad state.  No fix for the printf bug yet (2017-10-10).
-	* examples/ina219: A simple infinite loop that polls the INA219 sensor
-	  and displays the measurements.  From Sebastien Lorquet (2017-10-11).
-	* examples/ostest: Extend cancellation test to make sure that cancelable
-	  threads waiting on a message queue or on a signal can be canceled
-	  (2017-10-12).
-	* netutils/ftpc:  Fix some crazy comparisons to determine is a file is
-	  an absolute path.  Noted by Anthony Merlino (2017-10-13).
-	* examples/nx:  The NX example no longer supports single user mode
-	  (2017-10-14).
-	* examples/nxtext:  The nxtext example no longer supports single user
-	  mode (2017-10-14).
-	* examples/lcdrw:  Remove this example.  It violates the portable OS
-	  interface and cannot be retained (2017-10-14).
-	* graphics/traveler:  Restore most of what was removed in the previous
-	  commit.  That non-standard logic is currently needed by the simulation.
-	  It should be replaced with use of a framebuffer driver.  No longer
-	  supports single user graphics mode (2017-10-14).
-	* examples/nxhello now supports only multiuser mode (2017-10-14).
-	* examples/nximage now supports only multiuser mode (2017-10-14).
-	* system/lm75:  Fix a naming error in a dependency.  From Alan Carvalho
-	  de Assis (2017-10-14).
-	* examples/nxlines now supports only multiuser mode (2017-10-14).
-	* exampls/nxhello:  Increase the amount of time that the text is
-	  displayed before erasing it (2017-10-15).
-	* Add -n samples to lm75 app and replace Centigrade with Celsius.  From
-	  Alan Carvalho de Assis (2017-10-15).
-	* graphics/traveler: Convert to use the framebuffer driver (2017-10-16).
-	* examples/alarm: add options for reading alarm value and canceling it.
-	  From Juha Niskanen (2017-10-17).
-	* apps/fsutils/mkfatfs:  Move mkfatfs from the OS to here.  Not fully
-	  integrated on the initial commit (2017-10-20).
-	* apps/examples/adps9960:  Add ADPS-9960 example.  From Alan Carvalho de
-	  Assis (2017-10-23).
-	* This commit eliminates the ping command from NSH and replaces it with
-	  a ping 'built-in' at apps/system/ping.  The original NSH version of ping
-	  violated the portable POSIX interface and, hence, had to be removed.
-	  The new system/ping command uses the new IPPROTO_ICMP AF_INET datagram
-	  sockets to implement ping (2017-10-23).
-	* apps/system/ping6:  Use inet_ntop() to improve the appearance of the
-	  ping6 IPv6 address output.  Fix a typo and also a place where = used
-	  when == intended.  This commit removes the ping6 command from NSH and
-	  replaces it with the apps/system/ping6 built-in command.  The NSH ping6
-	  command had to be removed because it violated the portable POSIX OS
-	  interface.  The apps/system/ping6 command uses the sem-standard
-	  IPPROTO_ICMP6 socket interface (2017-10-24).
-	* apps/nshlib:  ifconfig improvements.  From Anthony Merlino (2017-10-24).
-	* nshlib:  mount command no long uses the non-standard OS interface
-	  foreach_mountpoint().  Now simply cats /proc/fs/mount when there are no
-	  arguments to the mount command (2017-10-26).
-	* nshlib:  df command no long uses the non-standard OS interface
-	  foreach_mountpoint().  Now simply cats /proc/fs/blocks or /proc/fs/usage
-	  (2017-10-26).
-	* Fix parsing of empty strings when CONFIG_NSH_CMDPARMS is not defined.
-	  Problem noted by Juha Niskanen (2017-10-27).
-	* apps/canutils/libobd2:  Add libobd2 for NuttX.  From Alan Carvalho de
-	  Assis (2017-10-28).
-	* apps/examples/obd2:  Add OBD2 example application.  From Alan Carvalho
-	  de Assis (2017-10-28).
-	* include/netutils/netlib.h:  Broaden socket definitions of previous
-	  commit.  Add definitions needed when only local Unix domain sockets are
-	  supported (2017-10-30).
-	* apps/examples/userfs:  Add a test case for verifying UserFS
-	  (2017-10-31).
-	* Fixed i2ctool write operation in `no restart` mode (flag `-n`).  It
-	  seems that I2C driver has changed a bit since i2ctool was written, so
-	  now i2ctool sends repeated start even if `no restart` flag (-n) was
-	  passed to it.  From Dmitriy Linikov (2017-11-01).
-	* Fixed misprint in cmd_wget.  From Dmitriy Linikov (2017-11-01).
-	* apps/examples/userfs:  Fix bad logic in test stat() implementation
-	  (2017-11-01).
-	* i8sak: Changes 'notif' to 'primitive' corresponding to the changes in
-	  the Kernel.  From Anthony Merlino (2017-11-01).
-	* Adds i8shark, a sniffer "adapter" that captures all 802.15.4 traffic,
-	  packages it into a Wireshark ZEP packet, and sends it to a host running
-	  Wireshark  From Anthony Merlino (2017-11-01).
-	* apps/examples/userfs:  Fix check for open with write+append mode
-	  (2017-11-01).
-	* apps/fsutils/mkfatfs:  When fsutils/mkfats was split off from the
-	  operating system, there were a few dangling things left.  Some
-	  references to functions in the OS (which are not available in the
-	  protected and kernel modes) and several types and function prototeypes
-	  that don't exist is apps/fsutils/mkfatfs (2017-11-02).
-	* Fixed the compilation of nsh_routecmds.c, broken after commit
-	  6b9d23c6aa0247c701acf1d0ecdaececf546342a.  From Dmitriy Linikov
-	  (2017-11-03).
-	* include/netutils/netlib.h:  In order to avoid pre-processing warnings,
-	  NETLIB_SOCK_FAMILY must always be assigned a value, even if there is no
-	  real meaning value for it (2017-11-03).
-	* i8sak: Channel setting is now saved locally, so when performing a
-	  startpan or assoc, the channel previously set is still used, even though
-	  the MAC layer gets reset.  Also fixes a few build issues.  From Anthony
-	  Merlino (2017-11-03).
-	* examples: add SMPS driver example.  From Mateusz Szafoni (2017-11-05).
-	* smps, powerled examples: fix floating point format in printf.  From
-	  Mateusz Szafoni (2017-11-05).
-	* apps/examples/userfs:  Handle the O_TRUNC open flag.  Fixes a bug with
-	  double freeing open data when dup'ed files are closed (2017-11-06).
-	* apps/examples/ltdc:  Remove apps/examples/ltdc.  It violates the
-	  portable POSIX interface by calling directly into OS code (2017-11-06).
-	* FTP: Adds support for IPv6 and fixes various transfer issues.   From
-	  Anthony Merlino (2017-11-06).
-	* netutils/ftpc:  Eliminate warnings about types of inputs to
-	  netlib_ipv4adaptr() and about ftp_cmd_pasv() being defined but not used
-	  (2017-11-12).
-	* apps/system/free:  Removed because it violates the portable POSIX OS
-	  interface (2017-11-13).
-	* apps/nshlib:  The free commands no longer used mallinfo() to get the
-	  state of the use heap.  Two reasons:  That is not useful information in
-	  the kernel build.  And (2) there are other memory resources of interest
-	  in other configurations such as the Kernel heap in PROTECTED and KERNEL
-	  builds, and the prog mem uses when FLASH is used to hold modifiable
-	  data.  The free command has been extended to just dump the content of
-	  procfs entries and to include all of these other memory resources of the
-	  procfs entries are available (2017-11-13).
-	* apps/nshlib:  Big simplification of last change.  /proc/kmm, umm, and
-	  progmem have been replaced with a single procfs file called
-	  /proc/meminfo.  The NSH free command now degenerates to a simple dump of
-	  /proc/meminfo (2017-11-13).
-	* apps/graphics/pdcurs34:  This commit brings the basic public domain
-	  pdcurses library into NuttX.  This library is complete but not yet
-	  usable because it still requires the NuttX interfacing code needed hook
-	  pdcurses into the NuttX graphics drivers.  Also test cases are needed to
-	  verify the pdcurses integration (2017-11-17).
-	* apps/examples/pdcurses:  Bring in pdcurses demos and make them conform
-	  to the NuttX coding style (not yet hooked into the build system)
-	  (2017-11-18).
-	* apps/graphics/pdcurs34:  Extend configuration to select the font size
-	  (2017-11-18).
-	* apps/example/pdcurses:  Add logic to build one of the several pdcurses
-	  demo/test programs (2017-11-18).
-	* apps/graphics/pdcurs34/nuttx:  Completes first cut at framebuffer
-	  rendering logic.  Add NuttX framebuffer color management and beginning of
-	  some rendering logic (2017-11-19).
-	* apps/examples/pdcurses/: Fix a few more bugs found in testing;  Brings
-	  in the remaining pdcurses demo programs (2017-11-19).
-	* apps/graphics/pdcurs34:  Add support for discrete joystick input.
-	  This is sufficient to get through all menuing tests that do not require
-	  text input (2017-11-22).
-	* apps/graphics/pdcurs34:  Add support for greylevels vs. RGB.  Define
-	  pdc_color_t based on pixel depth, not on specific color format.  Need to
-	  set the global COLORS or else all displays on monochrome (2017-11-22).
-	* i8shark:  Adds CONFIG_IEEE802154_I8SHARK_XBEE_APPHDR option to remove
-	  XBee's application header before sending to Wireshark. This option will
-	  corrupt any traffic received that does not include this application
-	  header.  From Anthony Merlino (2017-11-22).
-	* apps/wireless/ieee802154/i8sak: Adds ability to get/set rxonidle
-	  setting for MAC layer.  From Anthony Merlino (2017-11-xx).
-	* apps/examples/fb:  Fix calculation of a mask value (2017-11-22).
-	* NxWidgets:  Move from apps/NxWidgts to apps/graphics/NxWidgets
-	  (2017-11-24).
-	* apps/examples/pdcurses:  Add a very simple example that just shows the
-	  entire character set (7-bit only).  It adapts to the size of the
-	  framebuffer and, hence, can be used with very tiny displays.  In fact it
-	  looks really dumb on big displays (2017-11-24).
-	* apps/examples/fb:  Add a small delay between updating each rectangular
-	  region (2017-11-25).
-	* apps/examples: CONFIG_QENCODER was renamed to CONFIG_SENSORS_QENCODER:
-	  update README.txt.  From Fabio D'Urso (2017-11-25).
-	* apps/graphics/pdcurs34: Initial steps to support less than 8-pixel
-	  fonts on less than 8-bit display.  Calculation of font buffer stride
-	  must depend on the configured BPP.  Add first cut at function to copy a
-	  font into the font buffer; Make better use of macros to reduce code
-	  complexity (2017-11-27).
-	* apps/examples/nunchuck: Add Nunchuck example application.  From Alan
-	  Carvalho de Assis (2017-11-28).
-	* apps/graphics/pdcurs34:  Correct logic that sets the font buffer to
-	  the background color for the case of BPP < 8 (2017-11-29).
-	* apps/examples/pdcurses:  Clean up charset example so that the display
-	  geometry  is better on very wide displays (wide with respect to the width
-	  of a character) (2017-11-30).

-7.24 2018-03-02 Gregory Nutt <gnutt@nuttx.org>
-
-	* i8shark: Fixes special XBee compensation by purposely chopping off the
-	  FCS.  From Anthony Merlino (2017-12-08).
-	* nxplayer: Add support for http streaming in nxplayer.  From Masayuki
-	  Ishikawa (2017-12-19).
-	* Adds 'setlogmask' application that allows you to set the syslog
-	  priority via a simple command.  From Anthony Merlino (2017-12-19).
-	* apps/netutils/ftpc:  Fix some cornercases that could cause FTP to
-	  access past the end of valid data.  From Gregory Nutt (2017-12-21).
-	* examples/userfs: Add truncate() support for userfs.  From Gregory Nutt
-	  (2018-01-03).
-	* apps/nshlib:  Add support for a truncate command.  This will be used
-	  to test the new ftruncate file system support.  From Gregory Nutt
-	  (2018-01-04).
-	* nshlib/nsh_telnetd.c: Add support for telnet character mode.  From
-	  Masayuki Ishikawa (2018-01-10).
-	* apps/nshlib: Add support for '-n' option to the echo command.  From
-	  Masayuki Ishikawa (2018-01-10).
-	* apps/nshlib:  Add irqinfo command.  From Gregory Nutt (2018-01-12).
-	* apps/system/usbmsc: Added Kconfig options to configure write
-	  protection for each LUN.  From Fabio D'Urso (2018-01-14).
-	* apps/examples/lvgldemo:  Add lvgldemo example.  From Alan Carvalho
-	  de Assis (2018-01-16).
-	* apps/graphics/littlevgl:  Add littlevgl library.  From Alan Carvalho
-	  de Assis (2018-01-16).
-	* apps/examples/touchscreen:  Eliminate BOARDIOC_TSCTEST_SETUP.  From
-	  Gregory Nutt (2018-01-17).
-	* apps/examples/lvgldemo: Can no longer call boardctl() to initialize
-	  graphics hardware if needed.  From Gregory Nutt (2018-01-18).
-	* apps/netutils/netlib: Add default route in netlib_set_dripv4addr().
-	  From Masayuki Ishikawa (2018-01-19).
-	* system/stackmonitor:  Re-design the stack monitor so that it does not
-	  make forbidden calls directly into the OS, breaking the portable POSIX
-	  OS interface.  It now properly uses the PROCFS file system to glean
-	  information about stack usage.  From Gregory Nutt (2018-01-20).
-	* apps/nshlib:  Fix compile error when CONFIG_NSH_DISABLESCRIPT is not
-	  defined.  The field np_flags does not exist if scripting is disabled.
-	  From Gregory Nutt (2018-01-22).
-	* apps/examples/veml6070:  Add VEML6070 Application Example.  From Alan
-	  Carvalho de Assis (2018-01-28).
-	* examples/bmp180: Add BMP180 application example.  From Alan Carvalho
-	  de Assis (2018-02-04).
-	* apps/graphics/ft80x:  Add the FTDU FT80x GUI support library.
-	  Consists of some display list helpers, audio helpers, touch helpers, RAM
-	  access, register access etc.  From Gregory Nutt (2018-02-18).
-	* apps/examples/ft80x:  Add a test of the FT80x based on FTDI
-	  SampleApp.  Includes tests of GPU primitives and graphics co-processor
-	  commands From Gregory Nutt (2018-02-18).
-	* apps/graphics/ft80x and apps/examples/ft80x:  Fix a few compile-relate
-	  issues introduced with last merge.  From Gregory Nutt (2018-02-19).
-	* apps/examples/ft80x:  Add a few more demos of GPU primitive
-	  operations.  From Gregory Nutt (2018-02-19).
-	* Added ECANCELED condition to DEBUGASSERT-s checking sem_wait result.
-	  From Dmitriy Linikov (2018-02-20).

-7.25 2018-06-03 Gregory Nutt <gnutt@nuttx.org>
-
-	* apps/netutils/tftpc:  This commit modifies the TFTP client functions to
-	  use a data read/write callback instead of a file.  This allows TFTP to
-	  write to arbitrary destination (in my case, a MTD device - for firmware
-	  update).  Two new functions are introduced for this, named tftpget_cb and
-	  tftpput_cb. They are just made of most of the existing code.  The
-	  previously existing tftpget/tftpput functions are now wrappers on the new
-	  ones, with callbacks that read/write from files, so my modifications are
-	  backwards compatible with existing applications, eg the associated nsh
-	  commands don't need to be changed.  From Sebastien Lorquet (2018-03-09).
-	* apps/examples/ft80x:  Fix some size calculations.  Add option to disable
-	  primitive tests... just too boring to have to watch over and over again.
-	  Fix a typo in backlight fade logic; Fix error in formatted display light
-	  debug dump output.  From Gregory Nutt (2018-03-09).
-	* apps/examples/ft80x:  Text is handled by the coprocessor and, hence, must
-	  use RAM_CMD, not RAM_DL.  From Gregory Nutt (2018-03-09).
-	* apps/examples/ft80x:  Fix some errors in co-processor demos.  Correct an
-	  error in the spinner demo.  From Gregory Nutt (2018-03-10).
-	* apps/examples/netloop:  Update network loopback example so that it can be
-	  used to test TCP KeepAlive.  From Gregory Nutt (2018-03-12).
-	* apps/system/stackmonitor:  Fix comparison between pointer and zero
-	  character constant.  From Juha Niskanen (2018-03-13).
-	* apps/system and wireless:  Applications should use the standard clock()
-	  interface, not the internal NuttX clock_systimer() interface.  From
-	  Gregory Nutt (2018-03-14).
-	* apps/examples/lzf:  Add the test case from Marc Alexander Lehmann's
-	  LIBLZF3.6 librrary  From Boris Astardzhiev (2018-03-14).
-	* apps/examples/lzf:  lzf_compress() now expects the hash table as user
-	  allocated input parameter rather than declaring the huge array on the
-	  stack.  From Gregory Nutt (2018-03-15).
-	* apps/examples/lzf:  unlzf and lzcat are not supported.  From Gregory Nutt
-	  (2018-03-15).
-	* apps/examples/lzf: Fix name composition and set defaults early in main.
-	  From Boris Astardzhiev (2018-03-15).
-	* apps/examples/nsh and posix_spawn:  Must not call exec_setsymtab()
-	  directly.  That is a non-POSIX internal OS interface.  From Gregory Nutt
-	  (2018-03-16).
-	* apps/system/lzf:  Move the LZF tool from apps/examples/ to apps/system.
-	  From Gregory Nutt (2018-03-16).
-	* apps/system/lzf:  Don't build the LZF tool if the LZF library is not
-	  enabled.  From Gregory Nutt (2018-03-16).
-	* apps/system/lzf: Refactor so that the user is no longer required to
-	  generate the LZF header  From Boris Astardzhiev (2018-03-16).
-	* apps/system/lzf:  (1) The maximum block size is now configuration setting
-	  in order to give finer control over memory usage.  (2) The
-	  compression/decompression buffers have been moved out the stack and are
-	  now global variables.  This eliminates the need to set large stack sizes
-	  to use this utility.  (3) Added semaphore protection of all global
-	  variables for the case of the FLAT or PROTECTED builds.  Unlike the
-	  KERNEL build, the same global variables will be used by each instance of
-	  the LZF utility.  If you want thread safety, then you must either (a)
-	  serialize all access to the global variables, or (b) pack the global
-	  variables into a structure and allocate that structure on each execution
-	  of lzf_main().  From Gregory Nutt (2018-03-17).
-	* apps/examples/cromfs:  Add an example of how to build a CROMFS file
-	  system image.  From Gregory Nutt (2018-03-20).
-	* Remove canutils/libuavcan and examples/uavcan.  libuavcan has not built
-	  for a year or so.  The basic problem is that as NuttX advances, the old
-	  frozen version of libuavcan has become absolute because it violates the
-	  portable POSIX OS interface.  No one is maintaining the port so there is
-	  no alternative but to remove it.  From Gregory Nutt (2018-03-23).
-	* apps/examples/elf:  Extend the ELF program module demo so that you can
-	  use compressed ELF programs with CROMFS.  From Gregory Nutt (2018-03-24).
-	* apps/examples/elf:  Use strip command to make ELF binaries MUCH smaller.
-	  Add an option to strip debug symbols even if the debug symbols are
-	  enabled in the base code.  From Gregory Nutt (2018-03-25).
-	* apps/wireless/bluetooth/btsak:  Add a Bluetooth debugt tool.  From
-	  Gregory Nutt (2018-04-02).
-	* apps/netutils/netlib:  Various fixes needed to get a clean netlib build
-	  with Bluetooth only.  From Gregory Nutt (2018-04-03).
-	* apps/examples/cc3000:  Remove the CC3000 example.  From Alan Carvalho de
-	  Assis (2018-04-04).
-	* apps/examples/smps:  Fix typos in Kconfig.  All power, voltage, current
-	  values were strings with no default.  I assume they should be 'int' with
-	  what default?  From Gregory Nutt (2018-04-04).
-	* examples/powerled:  Add arch initialization; examples/smps: fixes in some
-	  printf and in Kconfig  From Mateusz Szafoni (2018-04-07).
-	* apps/examples/adxl372_test and lxm330spi_test:  Add ADXL372 and LSM330
-	  tests.  From Bob Feretich (2018-04-09).
-	* apps/examples/max31855: Add an example to read multiple max31855 sensors
-	  From Tiago Almeida (2018-04-09).
-	* apps/examples/ostest:  Do not call AIO test without
-	  CONFIG_EXAMPLES_OSTEST_AIO  From Juha Niskanen (2018-04-11).
-	* apps/examples/nxdemo:  Add nxdemo application  From Alan Carvalho de
-	  Assis (2018-04-28).
-	* apps/system/embedlog:  Support for embedlog data logging package from
-	  https://embedlog.kurwinet.pl/  From Michal Lyszczek (2018-05-06).
-	* nshlib/nsh_fscmds.c:  Add the mkfatfs -r option which can be used to
-	  specify the number of entries in the FAT12/FAT16 root directory.  From
-	  Boris Astardzhiev (2018-05-11).
-	* apps/system/zmodem:  Add an option to enable hardware flow control via
-	  termios.  Fix Makefile.host.  It was broken when zmodem.h was moved to
-	  apps/include/system.  Fix an incompatibility with the way that CRCs are
-	  calculated.  Allow stack size and priority to be configured.  From
-	  Gregory Nutt (2018-05-27).
-	* apps/system/zmodem:  Call tcflush() before closing the serial port.  This
-	  is necessary because that close operation may hang if hardware flow
-	  control is enabled.  Consider this scenario:  After the host sz runs on
-	  the host, it exits and leaves CTS high.  The target rz completes, and
-	  tries to close the serial port.  But if there is buffered Tx data, then
-	  the close will hang when it tries to drain the buffered Tx data since
-	  there is no where it can go.  tcflush() discards the buffered data and
-	  permits the close to continue.  There is additional logic in
-	  nuttx/drivers/serial needed to work with this.  From Gregory Nutt
-	  (2018-05-27).
-	* apps/, Various Makefiles:  Fix mixed references to nuttx/lib.  These need
-	  to be changed to nuttx/staging.  From Gregory Nutt (2018-05-30).
-	* Various fixes necessary to build the simulator under MSYS1.  From Gregory
-	  Nutt (2018-05-31).
-	* apps/Makefile and platform/Makefile:  At clean_context targets that are
-	  now invoked from the main nuttx/Makefile.  From Gregory Nutt (2018-05-31).

-
-	* apps/netutils/ftpc:  Fix handling of url-encoded strings  From
-	  Dmitriy Linikov (2018-06-04).
-	* apps/examples/i2sloop:  Add i2sloop application.  This application
-	  can be used to test I2S loopback like:  nsh> i2sloop &
-	  From Masayuki Ishikawa (2018-06-06).
-	* nsh_parse.c: fix 'while' and 'until' loop condition
-	  The loop condition logic was inverted:  while true; do echo "test";
-	  done
-	  would exit immediately, while using 'until' would stay in the loop.
-	  This is the opposite of how it is supposed to work.
-	  The reason is that 'state' was set wrong because 'whilematch' is a
-	  bool.  From Beat K�ng (2018-06-06).
-	* examples: Adds example to test framebuffer overlay  From Marco Krahl
-	  (2018-06-06).
-	* apps/examples/ostest:  Signal handling tests should use the same
-	  configurable stack size as used in other tests, not
-	  PTHREAD_STACK_DEFAULT.  From Gregory Nutt (2018-06-07).
-	* apps/system/taskset:  Add taskset command for SMP systems.  This
-	  command can be used to retrieve or set a process's CPU affinity.
-	  For example,
-
-	    nsh> taskset -p 4
-	    pid 4's current affinity mask: 2
-
-	    nsh> taskset -p 3 4
-	    pid 4's current affinity mask: 3
-
-	    nsh> taskset -p 1 busyloop &
-
-	  From Masayuki Ishikawa (2018-06-08).
-	* apps/gpsutils/minmea:  Include wchar.h in minmea.c file to fix wint_t
-	  error  From Alan Carvalho de Assis (2018-06-09).
-	* apps/examples/gps:  Add GPS example using MINMEA lib  From Alan
-	  Carvalho de Assis (2018-06-09).
-	* apps/Make.defs:  Fix an error introduced with recent chagne.
-	  MKKCONFIG may not be defined resulting in failure to create
-	  apps/Kconfig.  From Gregory Nutt (2018-06-11).
-	* examples/powerled: add arch initialization; examples/smps: fixes in
-	  some printf and in Kconfig
-	  testing: add Unity - unit testing library from ThrowTheSwitch.org
-	  From Mateusz Szafoni (2018-06-15).
-	* apps/wireless/wapi:  Remove dependency on CONFIG_EXPERIMENTAL from
-	  Kconfig  From Gregory Nutt (2018-06-17).
-	* Remove apps/interpreters/micropthon.  There are several reasons for
-	  this.  (1) the current version 1.3.8 is very old and no one is
-	  supporting it.  (2) the port only includes the core micropython logic
-	  and none of the Python libraries.  As such it is useless in any real
-	  application.  (3) There have recently been compile failures
-	  reported.  It looks like this is due to changes in newlib based
-	  toolchains that now bring in incompatible newlib header files.  See
-	  issue 104 at
-	  https://bitbucket.org/nuttx/nuttx/issues/104/build-micropython-138-error.
-	  With no one dedicated to the support of micropython, it can no longer
-	  be carried in the NuttX apps/ repository.  From Gregory Nutt
-	  (2018-06-18).
-	* apps/nshlib/README.txt:  Clarify arguments to the mkrd command. From
-	  Gregory Nutt (2018-06-22).
-	* testing/unity: add configuration options for exclude setjmp and
-	  output color  From Mateusz Szafoni (2018-06-23).
-	* apps/netutils/dhcpc:  Activates BINDTODEVICE if available, and break
-	  up some long lines  From Gregory Nutt (2018-06-25).
-	* apps/examples/tcpblaster:  Add TCP performance measurement test.
-	  From Gregory Nutt (2018-07-05).
-	* apps/examples/dsptest:  Add unit test for Nuttx DSP library  From
-	  Mateusz Szafoni (2018-07-07).
-	* apps/examples/helloxx: Add main() for CONFIG_BUILD_KERNEL  From
-	  Masayuki Ishikawa (2018-07-13).
-	* apps/examples/nsh:  Add logic to automatically register an
-	  application symbol table as part of NSH initialization.  From
-	  Masayuki Ishikawa (2018-07-13).
-	* There many occurrences of the global variable g_exports and the
-	  opportunity for collisions.  Make the global variable names unique.
-	  From Gregory Nutt (2018-07-14).
-	* apps/examples/nsh:  The symbol table name and size variable names can
-	  now be configured.  From Gregory Nutt (2018-07-14).
-	* import/:  Add Makefile.symtab which can be used to compile the
-	  dynamically created symbol table C file.  Add tools/mksymtab.sh.
-	  From Gregory Nutt (2018-07-15).
-	* apps/tools: Add +x to mksymtab.sh.
-	  apps/examples/nsh: Fix compile errors with
-	  CONFIG_EXAMPLES_NSH_SYMTAB=y  From Masayuki Ishikawa (2018-07-17).
-	* apps Makesystem:  Fix an error when building apps/ without nuttx/,
-	  using only the NuttX export package and assuming that the nuttx/
-	  directory in not even present.  In this case, the problem fixed where
-	  the apps/Make.defs file was selecting tools from the /tools directory
-	  which does not exist because TOPDIR=apps/import.  Instead, for this
-	  build case, I have not thought of any option but to duplicate scripts
-	  as necessary in the apps/tools directory.  Also added a top-level
-	  target to compile the symbol table.  Misc fixes: quoting in scripts,
-	  some errors in script syntax.  From Gregory Nutt (2018-07-17).
-	* apps/tools: Fix an error in mksymtab.sh  From Masayuki Ishikawa
-	  (2018-07-19).
-	* examples/lvgldemo/ and graphics/littlevgl/:  Update LVGL to version
-	  5.1.1  From Alan Carvalho de Assis (2018-07-19).
-	* fs/fat:  Clean up some name BS_ and MBR_ refer to the same record and
-	  should use the same naming (MBR_).  From Gregory Nutt (2018-07-22).
-	* Add definitions for the FAT boot record (FBR).  From Gregory Nutt
-	  (2018-07-22).
-	* nxplayer: Refactor nxplayer.c.  Apply netlib_parsehttpurl() and
-	  remove unnecessary usleep().  From Masayuki Ishikawa (2018-07-31).
-	* apps/system/i2c:  Adapt to rename I2C_M_RESTART->i2C_M_START.
-	  I2C_M_NOSTOP should be in flags of first message in every write-read
-	  and write-write message sequence.  From Gregory Nutt (2018-08-03).
-	* include/netutils/netlib.h:  Eliminate a warning about AF_UNSPEC and
-	  AF_INET not defined.  From Gregory Nutt (2018-08-03).
-	* Introduce a build system for loadable apps for nsh.
-	  apps/Make.defs:  Override COMPILE and COMPILEXX macros to compile
-	  loadable apps.  To make loadable apps, -DLOADABLE_APP is added to the
-	  flags.  Also, introduce ELFLD to link a lodable app.
-	  apps/Application.mk:  Add .build target in case of 'LOADABLE=y' which
-	  is used to link a final loadable application and install the app to
-	  apps/bin.
-	  apps/Makefile: Add SYMTABSRC and SYMTABOBJ variables for loadable
-	  apps which will be generated under the apps directory.  Add
-	  make_symbols target which will be called when all applications are
-	  installed to generate symtab_app.c which is used for nsh to inform
-	  symbol information to the NuttX kernel.  If the application is
-	  specified to 'm', the variable 'LOADABLE' must be defined here. Also
-	  note that other variables (PRIORITY and STACKSIZE) can only be used
-	  for built-in apps.
-	  apps/nshlib/Kconfig: Add 'option modules' to NSH_FILE_APPS so that a
-	  user can change an application configuration to tristate (y/n/m)
-	  apps/examples/hello and helloxx:  Apply changes to support a loadable
-	  app.  Makefile: Change the condition to build. By default, the
-	  application is not selected (i.e. 'n'), so if other states (i.e. y/m)
-	  are selected, the application will be compiled.    Please note that
-	  the variable 'LOADABLE' must be defined in each application Makefile
-	  if you want to make a loadable app.  Change the application state
-	  from bool to tristate in the Kconfig file.  Add LOADABLE_APP
-	  condition to main().  From Gregory Nutt (2018-08-03).
-	* apps/examples/elf:  CROMFS and ROMFS configuration currently only
-	  usable in FLAT build.  Add configuration to use ELF objects on
-	  external media like SD card or USB drive instead.  From Gregory Nutt
-	  (2018-08-04).
-	* apps/examples/elf:  If the test ELF files are on media in removable
-	  media such as SD or USB FLASH, the wait until the media has been
-	  installed and initialized before starting the test.  From Gregory
-	  Nutt (2018-08-04).
-	* apps/examples/module:  Add support for CROMFS and for stripping
-	  symbols from ELF module binaries.  From Gregory Nutt (2018-08-05).
-	* examples/module:  Add support for automounting removable media.  This
-	  involves a wait for the block driver to become available before
-	  performing the mount.  From Gregory Nutt (2018-08-05).
-	* apps/system/cle:  Usage improvements including command line history
-	  (taken from readline) and support for addition control characters.
-	  From mst (2018-08-05).
-	* apps/nshlib:  Add parsing support for back-slash quoted characters.
-	  Currently only implemented properly if CONFIG_NSH_ARGCAT is also
-	  selected.  This commit is in response to Bitbucket Issue 11 opened by
-	  Maciej W�jcik  From Gregory Nutt (2018-08-06).
-	* apps/examples/module:  When built in the PROTECTED or KERNEL modes,
-	  the symbol table is not built by the application.  That is because
-	  the build will fail since the kernel module depends on internal OS
-	  symbols thar are not available to the application build.  With this
-	  change the examples does not attempt to build the kernel symbol table
-	  in these modes.  Instead it just copies the kernel module symbol
-	  table into the nuttx/pass1 directory where it can be build directly
-	  into the OS during pass2 of the build.  From Gregory Nutt (2018-08-07).
-	* nsh: add inverted logic support in the form of 'if ! <cmd>'  From
-	  Beat K�ng (2018-08-11).
-	* apps/nshlib:  I was able to cause an assertion with some typos in
-	  testing the 'fi' command.  Not an important thing, but this will
-	  protect against the assertion.  From Gregory Nutt (2018-08-11).
-	* examples/calib_udelay:  Add tool for calibrating
-	  CONFIG_BOARD_LOOPSPERMSEC  From Juha Niskanen (2018-08-14).
-	* apps/builtin/Makefile.  This commit changes apps/builtin to search
-	  the registry recursively. By supporting directories, external
-	  projects can install the hooks into the registry and easily clean
-	  them up and reinstall if something needs to be updated.  Based on an
-	  idea from Anthony Merlino.  From Gregory Nutt (2018-08-15).
-	* apps/system/popen:  Add an implementation of the standard popen() and
-	  pclose() OS interfaces.  These are implemented as applications vs.
-	  part of the OS because they depend on NSH.  Untested on initial
-	  commit.  From Gregory Nutt (2018-08-17).
-	* apps/examples/popen:  Add a test of popen/pclose.
-	  apps/system/popen:  Fix some errors found using the new popen/pclose
-	  test.  From Gregory Nutt (2018-08-17).
-	* apps/Application.mk:  If a loadable module is generated the we need
-	  to add logic to remove the loadable module in the 'make clean'
-	  logic.  From Gregory Nutt (2018-08-17).
-	* apps/system/system and popen:  Adapt so that these can be used in the
-	  KERNEL build mode.  In this case, simply replace task_spawn() with
-	  posix_spawn().  This depends on the existence of some environment
-	  where /bin/sh exists and can be used to execute one NSH command.  For
-	  the case of system(), this change was more complete because it
-	  previously used task_create().  Now it uses either task_spawn() or
-	  posix_spawn(), depending upon the configuration.  From Gregory Nutt
-	  (2018-08-18).
-	* apps/system/nsh:  Move apps/examples/nsh to apps/system/nsh.  It has
-	  become so entrenched that it is hardly an example these days.  May as
-	  well formalized it as a system task.  From Gregory Nutt (2018-08-18).
-	* i8sak: i8sak daemon now gets shutdown if not in use. Previously, once
-	  the i8sak daemon was started, by running any command, it would stay
-	  running. This means that if you want to use i8sak to setup your
-	  network, but then want exclusive access to the char device, or
-	  network device, you have to manually shutdown the i8sak daemon. Now
-	  the daemon stays active as long as required to finish any commands,
-	  or stays open if a new command keeps it on, but when all work is
-	  finished, it shuts down.  From Anthony Merlino (2018-08-19).
-	* Remove illegal calls into OS to initialize BINFMT support.  This must
-	  be moved to the board initialization logic within the OS.  From
-	  anchao (2018-08-22).
-	* Move a copy of define.bat and sh from nuttx/tools to apps/tools so
-	  that they will be available for the import build.  From Gregory Nutt
-	  (2018-08-22).
-	* apps/nshlib:  Expand reboot and poweroff commands to include a
-	  second, optional mode argument  From ligd (2018-08-22).
-	* apps/system/zmodem:
-	  fix error "sz_main.o: No such file or directory"
-	  support -p <path> for rz to change the folder for the received file
-	  switch debug output from printf to syslog
-	  send the next packet for ZME_ACK in ZMS_SENDING to avoid rz on the
-	  host side stuck
-	  make send work reliable even without hardware flow control  From
-	  Xiang Xiao (2018-08-23).
-	* apps/system/system/system.c:  Add 'const' to make function signature
-	  compatible with OpenGroup.org  From Xiang Xiao (2018-08-23).
-	* apps/system/ping and ping6:  Send ID and seqno in network byte
-	  order.  From Xiang Xiao (2018-08-23).
-	* apps/system/ping and ping6:  Change dependency in ping and ping6
-	  Kconfig.  These may be implemented in users sockets and, hence, may
-	  need to be available even if ICMP and ICMPv6 sockets are not support.
-	  From Xiang Xiao (2018-08-23).
-	* apps/system/cu/cu_main.c: (1) Protect from possible re-definition of
-	  signal values, (2) Fix CU ctrl-C hand when remote core hang.  From
-	  ligd (2018-08-23).
-	* apps/fsutils/mksmartfs:  Add a check to see if the SmartFS is already
-	  formatted.  apps/nshlib:  Add a force flag (-f) to mksmartfs.  SmartFS
-	  will be formatted only if (1) the FLASH does not already hold
-	  a SmartFS, or (2) the force flag is set  From Xiang Xiao (2018-08-23).
-	* apps/nshlib: (1) NSH prompt string is now configurable. nsh> is still
-	  the default.  (2) Increase the default configuration for the maximum
-	  number of command line arguments to 7 (CONFIG_NSH_MAXARGUMENTS).
-	  This is needed for 'mount' with the -o option.  From Xiang Xiao
-	  (2018-08-23).
-	* apps/examples/module/Makefile:  Correct module example build.  Change
-	  to LDLIBs were causing a failure due to a non-existent (any
-	  unnecessary) library in this case.  From Gregory Nutt (2018-08-23).
-	* apps/, most main() function: Correct CONFIG_BUILD_LOADABLE usage
-	  Loadable apps/: Correct loadable symbol table generate
-	  apps/system/ubloxmodem:  Fix build break
-	  apps/examples/ostest: start restart/waitpid/user test from main loop
-	  apps/nshlib:  Expand reboot and poweroff commands to include a
-	  second, optional mode argument
-	  An attempt to fix build issues.  Does not work.
-	  apps/examples/ostest:  Fix some inappropriate renaming of static
-	  functions introduced with recent patches.
-	  apps/builtin/exec_builtin.c:  Fix a error introduced by recent
-	  comments.  Found in build testing.
-	  apps/builtin/exec_builtin.c:  Try posix_spawn if builtin apps do not
-	  have have an entry point.
-	  apps/Application.mk: introduce MODULE config to simplify tristate(m)
-	  apps/nsh:  Change the nuttx shell module type to tristate
-	  apps:  Add loadable application support
-	  script/mksymtab:  Generate symbol table name by default
-	  apps/builtin:  Allow loadable applications can register with
-	  apps/builtin.  From anchao (2018-08-23).
-	* Replace all ASSERT calls to DEBUGASSERT  From Xiang Xiao (2018-08-24).
-	* apps/examples/sotest and modules:  With recent changes, LDLIBS is
-	  initialized to bad value, at least in certain contexts.  From Gregory
-	  Nutt (2018-08-24).
-	* apps/nshlib:  Add control-C support for terminating built-in and
-	  exec'ed file tasks.  From ligd (2018-08-26).
-	* apps/nshlib/Kconfig:  Move 'option modules' from NSH_FILE_APPS to
-	  BUILD_LOADABLE  From anchao (2018-08-27).
-	* apps/system/nxplayer:  Release buffer before session and release
-	  semaphore in nxplayer_setvolume
-	  system/nxplayer/nxplayer.c:  Remove & for apb->samp reference. It is
-	  already a pointer.  From Xiang Xiao (2018-08-27).
-	* system/nxplayer/nxplayer.c:  Add playraw command  From ZhongAn
-	  (2018-08-27).
-	* apps/system/nxrecorder:  Add nxrecorder application  From ZhongAn
-	  (2018-08-27).
-	* nettest: fix typo: NET_LOOPBACK -> CONFIG_NET_LOOPBACK
-	  nettest: fix compilation error. Should enable NET_SETSOCKOPT for
-	  preventing compilation error.  From EunBong Song (2018-08-28).
-	* apps/system/cu:  SIGKILL is more appropriate that SIGINT in this
-	  circustance.  From Gregory Nutt (2018-08-28).
-	* apps/: Call BOARDIOC_FINALINIT after start-up script (or immediately
-	  after BOARIOC_INIT is there is no start-up script).  From ligd
-	  (2018-08-28).
-	* apps/system/cu:  Fix undefined SIGKILL if CONFIG_SIG_DEFUALT is not
-	  defined.  From Gregory Nutt (2018-08-29).
-	* apps/nshlib/nsh_console.c: Do not dereference NULL 'pstate'  From
-	  Juha Niskanen (2018-08-29).
-	* apps/system/i2c: Allow registers besides 0x00 in the dev command.
-	  From akob Haufe (2018-08-30).
-	* system/i2c/i2c_main.c:  Fix a backward comparison.  Noted by Jakob
-	  Haufe.  From Gregory Nutt (2018-08-30).
-	* apps/ostest/suspend.c:  Add a small test for SIGSTOP, SIGCONT, and
-	  SIGKILL actions.  From Gregory Nutt (2018-08-30).
-	* examples/ostest/signest.c:  Attempt to make the nested signal test
-	  compatible with the suspend/resume test.  Some signals cannot be
-	  caught when the suspend/resume configuration is in place.  From
-	  Gregory Nutt (2018-08-30).
-	* apps/ examples/dhtxx: Example for the DHTxx sensor.  From Ouss4
-	  (2018-09-01).
-	* apps/nshlib:  When using waitpid() to wait for a built-in application
-	  or a file application to exit.  Add the WUNTRACED options to so the
-	  the waitpid() call will also be awakened if the waited-for task is
-	  stopped as well.  From Gregory Nutt (2018-09-02).
-	* apps/: Modification to build system: Unified application compilation
-	  rules  From anchao (2018-09-03).
-	* apps/:  Resolve some make dependency failures.  From anchao
-	  (2018-09-03).
-	* apps/platform/Makefile:  Fix missing dependency path in Makefile.
-	  From Gregory Nutt (2018-09-03).
-	* apps/:  Fix build break in case sama5d4-ek/elf configuration.  Also
-	  fix a patch problem in mkromfsimg.h.  From anchao (2018-09-04).
-	* Application.mk:  Even on Cygwin, GNU make insists that targets use
-	  Unix style paths.  System/progmem:  Rename the install application to
-	  progmem.  This generates a target install: which collides with the
-	  install:: target in Application.mk.  From Gregory Nutt (2018-09-04).
-	* Makefile:  platform/Makefile must have BIN_DIR defined on command
-	  line even though it is not used.  This is because in the Cygwin
-	  build, the value of 'BIN_DIR' is passed to 'cygpath'.  'cygpath will
-	  fail if BIN_DIR is not defined.  From Gregory Nutt (2018-09-04).
-	* Makefile:  Fix more places where attempts to use Unix-style paths
-	  with native Windows toolchain.  tools/mksymtab.sh:  Add a check just
-	  to prevent 'cat' of an empty file list from failing.  Right not the
-	  root problem is that the are not executables being built or installed
-	  in the exe/ directory.  That needs to be done by 'make import' but is
-	  not happening.  From Gregory Nutt (2018-09-04).
-	* Makefile:  In the make import target for kernel build, we must make
-	  all objects and populate libapps.a.  Application.mk:  the PROGIST
-	  must be executed unconditionally to support the kernel build.  From
-	  Gregory Nutt (2018-09-04).
-	* Application.mk:  Fix some issues when building directories such as
-	  fsutils/mkfatfs that have no mainobj.  In this case, the MAINSRC is
-	  undefined and it would generate a bad linker command line.  From
-	  Gregory Nutt (2018-09-04).
-	* Application.mk:  Add module install logic.  Possibly only needed in
-	  KERNEL build mode? Makefile:  Simplify import target for KERNEL
-	  build.  A symbol table is not needed because the KERNEL-mode programs
-	  are completely linked.  Also fix missing deletion in clean and
-	  distclean targets.  tools/mksymtab.sh:  Fix a typo introduced in
-	  previous commit.  From Gregory Nutt (2018-09-04).
-	* Makefile: 'make distclean' should remove the exe subdirectory  That
-	  target must return the directory back to the state is was in when
-	  freshly cloned.  Application.mk:  Add logic to strip unnecessary
-	  symbols after installing a module.  But then I commented it out.
-	  Wouldn't we want to keep the symbols if we planned to debug the
-	  module?  In apps/examples/elf, there is configuration option to
-	  determine if the symbols should be stripped or not.  Perhaps that is
-	  needed here too?  From Gregory Nutt (2018-09-04).
-	* Application.mk: Generate temporary name for linker object  From
-	  anchao (2018-09-05).
-	* netutils/ping: remove unsupported ping.  netutils/ping is not
-	  supported anymore.  It's better to remove this folder for preventing
-	  confusing.  ping is supported by system/ping.  From EunBong Song (2018-09-05).
-	* Application.mk: Fix to not register a builtin app when BUILD_MODULE=y
-	  apps/tools: Fix to generate CONFIG_SYSTEM_NSH_SYMTAB_COUNTNAME in
-	  mksymtab.sh.  From Masayuki Ishikawa (2018-09-07)

-7.27 2018-11-14 Gregory Nutt <gnutt@nuttx.org>
-
-	* Directory.mk:  Fix distclean targets of directory makefiles was not
-	  removing generated Kconfig files.  There is then no way to remove this
-	  Kconfig files without manually deleting them one at a time.  From Gregory
-	  Nutt (2018-09-08).
-	* apps/examples/tcpblaster:  Add an option to use poll() to pace input or
-	  output.  From Gregory Nutt (2018-09-10).
-	* apps/examples/tcpblaster:  Select CONFIG_LIBC_FLOATINGPOINT
-	  automatically.  Units in output are wrong:  Not Kbps bus Kb/Sec.  From
-	  Gregory Nutt (2018-09-10).
-	* apps/Application.mk:  Fix some build issues.  (1) Unable to found target
-	  'context' when CONFIG_NSH_BUILTIN_APPS disabled. (2) Unable to generate
-	  multiple programs.  From Chao An (2018-09-12).
-	* Fixes i8sak name. Accidentally renamed to i8ask in recent changes  From
-	  Anthony Merlino (2018-09-12).
-	* apps/examples/udpblaster:  Add option to use poll() on output (only).
-	  Also picks up some fixes to various typographical errors.  From Gregory
-	  Nutt (2018-09-14).
-	* Correct some network-related configuration variable names.  All *_MTU
-	  defines were changes to *_PKTSIZE gut that was not reflected in apps/
-	  From Gregory Nutt (2018-09-14).
-	* Combine the NxWidgets repository into the apps/ repository:
-
-	  - Remove old NxWidgets directory
-	  - Merge remote-tracking branch 'NxWidgets/master'
-	  - Move NxWidgets files into graphics/NxWidgets
-	  - Integrate configuration/build system
-	  - Fix file paths in file headers.  Remove some duplicate tools.
-	  - Add new NxWidgets Unit Test configuration and build logic.
-
-	  From Gregory Nutt (2018-09-15).
-	* Directory.mk:  If the current directory contains a Kconfig file and
-	  MENUDESC is not defined, then Directory.mk must not trash the Kconfig in
-	  the current directory.  From Gregory Nutt (2018-09-16).
-	* This commit moves the NxWidgets include directories into the correct
-	  position in the apps/ source tree.
-
-	  - Clean-up some include path problems introduced with the previous set of
-	    changes.
-	  - app/include/graphics, apps/NxWidgets/UnitTests:  Update include paths
-	    for file in new location.
-	  - apps/NxWidgets/nxwidgets and nxwm:  Update include paths for file in new
-	    location.
-	  - apps/graphics/NxWidgets:  Move nxwidgets and nxwm include/ directories
-	    to apps/include/graphics
-
-	  From Gregory Nutt (2018-09-16).
-	* apps/nshlib:  Correct maximum number of arguments that can be provided to
-	  the mksmartfs command.  From Eunbong Song (2018-09-18).
-	* apps/examples/adc/Kconfig:  CONFIG_BOARDCTL_ADCTEST does not exist anymore
-	  and should removed as a dependency.  From Eunbong Song (2018-09-18).
-	* nshlib/, examples/:  Update to show newer file system object types
-	  returned by stat().  From Gregory Nutt (2018-09-22).
-	* Adapt the existing fstest example for SPIFFS:
-
-	  - examples/fstest:  For SPIFFS, add garbage collection and file system
-	    integrity IOCTL calls.  This was to avoid running out of FLASH space
-	    while running the fstest (ENOSPC=28).  However, it does not work.. still
-	    runs out of memory.
-	  - apps/examples/fstest:  Call statfs() and show state of file system on
-	    each loop.
-	  - apps/examples/fstest:  Fix a situation where a file system under test
-	    could cause the fstest to get stuck in an infinite loop.  From Gregory
-	    Nutt (2018-09-27).
-	* - apps/examples/fstest:  Add logic to dump logic content of SPIFFS
-	  - apps/examples/fstest/Kconfig: SPIFFS GC and integrity check option
-	    interferes SPIFFS.  Appears to corrupt the file system.  Now marked
-	    EXPERIMENTAL.  From Gregory Nutt (2018-09-28).
-	* - apps/examples/fstest:  Ignore EINTR errors while reading or writing.
-	  - apps/examples/fstest:  Add configuration option to customize stack
-	    size.  Detect when the media is full and stop writing files.  Report
-	    total file size.  From Gregory Nutt (2018-09-29).
-	* apps/netutils/netlib/netlib_parsehttpurl.c:  Correct handling of long URLs
-	  as noted in Bitbucket issue #119 (in the nuttx/ repository, not the apps/
-	  repository).  From Gregory Nutt (2018-09-30).
-	* apps/nshlib:  Add support for the 'env' command.  From Gregory Nutt
-	 (2018-09-30).
-	* apps/nshlib:  Add support for NSH local variables if CONFIG_NSH_VARS are
-	  set.  These are like environment variables but are local to NSH.  The
-	  importance of this is that these variables are *not* inherited when NSH
-	  creates a new task.  The new command 'export' was added.  In this case,
-	  the NSH variable will be promoted to an environment variable and will then
-	  be inherited by any tasks executed by NSH.  From Gregory Nutt (2018-10-01).
-	* apps/nshlib:  If CONFIG_NSH_VARS=y, the NSH 'set' command with no argument
-	  will list all of the local NSH variables.  From Gregory Nutt (2018-10-02).
-	* i8sak: Properly shuts down event thread.  From Anthony Merlino (2018-10-06).
-	* "dst" overflow protection when base64 string ends with "="  From Aleksandr
-	  Vyhovanec (2018-10-19).
-	* apps/system/progmem:  Remove this utility.  It makes illegal direct calls
-	  into the OS.  From Gregory Nutt (2018-10-19).
-	* apps/examples/mlx90614:  Add mlx90614 test example  From Alan Carvalho de
-	  Assis (2018-10-28).
-	* apps/netutils/netlib and apps/examples/igmp:  Adapt to use the corrected,
-	  semi-standard version of struct ip_msfilter.  From Gregory Nutt
-	  (2018-10-29).
-	* wireless/ieee802154/i8sak: Adds support for getting/setting transmit
-	  power.  From Anthony Merlino (2018-11-01).
-	* examples/mlx90614/mlx90614_main.c:  Include support to change device
-	  address on mlx90614  From Alan Carvalho de Assis (2018-11-02).
-	* apps/include/netutils/ipmsfilter.h:  Eliminate error generated by bad
-	  pre-processor logic.  From Gregory Nutt (2018-11-02).
-	* apps/examples/mld:  Add a test of MLD.  Provides a mechanism for some
-	  low-level bring-up of MLD.  From Gregory Nutt (2018-11-04).
-	* apps/Makefile:  Fix Windows native build patch extension.  From Anatol
-	  Ivanov (2018-11-05).
-	* apps/examples/ina226:  Added INA226 example  From Daniel P. Carvalho
-	  (2018-11-05).
-	* apps/examples/mld/mld_main.c:  Improve test by periodically dumping the
-	  content of /proc/net/mld (if available).  From Gregory Nutt (2018-11-06).
-	* apps/examples/mld:  Add logic to set up the routing table before
-	  attempting to send the multicast packet.  From Gregory Nutt (2018-11-07).
-	* nshlib/nsh_console.c: Add fflush to nsh_consolewrite().  This resolves
-	  this problem:
-
-	  > cat /dev/ttyCP &
-	  > echo ls >/dev/ttyCP
-
-	  Can't get the 'ls' result immediately, because 'cat' cmd uses
-	  nsh_consolewrite() and that uses fwrite with no fflush. We can get the
-	  'ls' result after type '\n', because nsh will fflush output when get
-	  '\n'.  From ligd (2018-11-07).
-	* nshlib/nsh_fsutils.c:  nsh_catfile() should not append '\n' if the last
-	  char in file is already '\n'  From Xiang Xiao (2018-11-07).
-	* nshlib/nsh_netinit.c:  Move call netlib_icmpv6_autoconfiguration() into
-	  nsh_net_bringup() like DHCP  From Xiang Xiao (2018-11-07).
-	* nshlib/nsh_envcmds.c:  Fix warning g_oldpwd defined but not used
-	  [-Wunused-const-variable]  From Xiang Xiao (2018-11-07).
-	* apps/system/hexed/src/bfile.c:  Fix memory leak  From zhuyanlin
-	  (2018-11-07).
-	* apps/system/i2c/i2c_get.c:  Fix i2c_msg freq initialization problem.  Typo
-	  prevent I2C frequency initialization in a struct i2c_msg.  From From:
-	  dongjiuzhu (2018-11-07).
-	* apps/system/system.c:  Fix warning when passing argument 6 of 'task_spawn'
-	  from incompatible pointer type [-Wincompatible-pointer-types]  From Xiang
-	  Xiao (2018-11-07).
-	* apps/system/vi/vi.c:  Do not print error if the file does not exist.  From
-	  anchao (2018-11-07).
-	* apps/netutils/chat and apps/examples/chat:  'constify' chat variables and
-	  parameters  From Xiang Xiao (2018-11-07).
-	* apps/netutils/pppd:  Refine and fix pppd code.  From Xiang Xiao
-	  (2018-11-07).
-	* apps/examples/mld:  Fix incorrect format of IPv6 Multicast address.  This
-	  resolves the UDP sendto() problem.  From Gregory Nutt (2018-11-07).
-	* apps/:  Rename BINFMT_EXEPATH to LIB_ENVPATH.  From anchao (2018-11-08).
-	* apps/examples/gpio:  Align with GPIO driver update  From wangyanjiong
-	  (2018-11-08).
-	* - system/ping/ping.c and system/ping6/ping6.c:  Set optind to zero in the
-	    error case
-	  - system/ping/ping.c and system/ping6/ping6.c:  Move all ping preparation
-	    work into icmp_ping
-	  - system/ping/ping.c and system/ping6/ping6.c:  Support -W <timeout> and
-	    -s <size> option
-	  - system/ping/ping.c and system/ping6/ping6.c:  Decouple the output from
-	    ping logic
-
-	  From Xiang Xiao (2018-11-08).
-	* apps/system/ping and pings and apps/netutils/ping:  Extract icmp ping and
-	  icmpv6 ping6 logic from system/ to C-callable library in netutils/.  From
-	  ligd (2018-11-08).
-	* apps/examples/webserver/Kconfig:  The webserver "app" allows for DHCP
-	  client to be enabled. However, the Kconfig infrastructure does not contain
-	  EXAMPLES_WEBSERVER_DHCPC config.
-
-	  Based on patch from "Anonymous" attached to Bitbucket Issue #130  From
-	  Gregory Nutt (2018-11-08).
-	* NxWidgets improvements
-
-	  - NxWidgets: fix garbage returned when CCycleButton::getValue() is called
-	    after removeAllOptions().
-
-	    It's a bit questionable whether returning 0 here is reasonable or
-	    if it would be better to assert(). But either is better than reading
-	    into random memory and returning a garbage value.
-
-	  - NXWidgets CScrollingPanel: Don't draw outside the widget area.
-
-	    The port->move() function doesn't support clipping the
-	    copied area to the client area, so we have to manually
-	    calculate the part that can be moved without going outside
-	    the widget.
-
-	  - CNxString: Add string + operator and ::format() function
-
-	  - CNumericEdit: Add option to include unit name after the value
-
-	  - NxWidgets: CNxWidget: Make useWidgetStyle() public
-
-	    Makes it easier to update styles when multiple controls are nested.
-
-	  - NxWidgets: Add CLabelGrid control for displaying text in grid format.
-
-	  From Petteri Aimonen (2018-11-09).
-	* apps/system/ping6:  Remove NET_USRSOCK from Kconfig dependence list  From
-	  Xiang Xiao (2018-11-09).
-	* graphics/NxWidgets/nxwidgets/src/clabelgrid.cxx:  Change old-style dbg()
-	  to current ginfo().  From Gregory Nutt (2018-11-09).
-
-7.28 2019-01-19 Gregory Nutt <gnutt@nuttx.org>
-
-	* netutils/webserver:  The webserver/httpd app is currently broken when script
-	  support is enabled (CONFIG_NETUTILS_HTTPD_SCRIPT_DISABLE). The root cause
-	  has been tracked down to the "Content-length" not being available ahead of
-	  time in this case (length of -1 passed to send_headers() ).  On the other
-	  hand, the server closing the socket does not result in FIN being sent
-	  to the browser either (FIN not supported by NuttX yet).
-
-	  Simple solution: Add support for HTTP Chunked Encoding to
-	  webserver/httpd (attached patch).
-
-	  The attached patch is simple. It adds a configuration option to enable
-	  chunked encoding. When enabled, the implementation will auto-detect the
-	  cases where content length is not available ahead of time, and will
-	  automatically engage chunked encoding transfers.
-
-	  Without this patch, the browser/client hangs forever, as it is
-	  expecting more data. With this patch, the browser displays the
-	  content.  From Vlado Vidovic (2018-11-23).
-	* From patch attached to nuttx/ Bitbucket Issue #136 from Vlado Vidovic:
-
-	  The patch provided in issue 135, which adds support for HTTP Chunked
-	  Encoding, covers all paths in the webserver app except CGI callbacks.
-	  As a result, if a page being served happens to use CGI, it could
-	  generate stream content that does not comply with HTTP Chunked Encoding.
-
-	  The patch attached amends the webserver app's CGI callbacks to use the
-	  HTTP Chunked Encoding sender function instead of using send()
-	  directly.  From Gregory Nutt (2018-11-23).
-	* apps/system/critmon:  Add a daemon to monitor critical section usage.
-	  From Gregory Nutt (2018-11-24).
-	* apps/wireless/bluetooth/btsak: 'bt bnep0 info' outputs a reversed addr.
-	  It should print BDAddr: aa:bb:cc:dd:ee:ff instead of BDAddr:
-	  ff:ee:dd:cc:bb:aa  From Lwazi (2018-11-25).
-	* Various initialization functions in configs/:  Change /dev/slcd to
-	  /dev/slcd0 for consistency  From Alan Carvalho de Assis (2018-11-25).
-	* wireless/bluetooth/btsak:  Fix some errors in btsak  From Lwazi Dube
-	  (2018-11-27).
-	* system: Fixes build error; There is no result variable, use errcode
-	  instead.  From Anthony Merlino (2018-11-28).
-	* apps/system/critmon/Makefile:  Stack size and priority reversed.  From
-	  Daniel Pereira Carvalho (2018-11-29).
-	* apps/nshlib: Add support to use SLCD as NSH Console  From Alan Carvalho
-	  de Assis (2018-11-29).
-	* wireless/bluetooth/btsak/btsak_main.c: Fix address parsing  From Lwazi
-	  Dube (2018-11-30).
-	* apps/wireless/bluetooth/btsak: Add connect and disconnect commands to
-	  btsak  From Lwazi Dube (2018-12-02).
-	* apps/nshlib/nsh_romfsetc.c:  Add support for CROMFS start-up script.
-	  From David Sidrane (2018-12-06).
-	* apps/wireless/bluetooth/btsak: Remove unnecessary gatt get commands.
-	  From Lwazi Dube (2018-12-08).
-	* apps/testing:  Move apps/examples/ostest to apps/testing/ostest.  From
-	  Gregory Nutt (2018-12-12).
-	* apps/wireless/bluetooth/btsak/btsak_scan.c: Fix reversed address  From
-	  Lwazi Dube (2018-12-17).
-	* apps/system/nsh/nsh_main.c:  Set NSH priorirty if the NSH task was
-	  scheduled at a different priority than the configured priority.  From
-	  Gregory Nutt (2018-12-20).
-	* apps/system/configdata:  Adds an "cfgdata" command which allows
-	  manipulation of the /dev/config items via the command line.  One such
-	  use for this utility would be to set a "macaddr" configdata item, etc.
-	  The utility is sort-of like a u-boot env variable edit function:
-
-	  For instance, to set a "macaddr" when the new CONFIG_MTD_CONFIG_NAMED
-	  option is selected, you would do:
-
-	  nsh> cfgdata set macaddr [0xfc 0x01 0x0b 0x45 0xa1 0x12]
-	  (The brackets denotes an array of bytes)
-	  nsh> cfgdata set hostname myboard
-
-	  or using the old ID,INSTANCE numeric method:
-
-	  nsh> cfgdata set 0,0 [0xfc 0x01 0x0b 0x45 0xa1 0x12]
-	  (The brackets denotes an array of bytes)
-	  nsh> cfgdata set 1,0 myboard
-
-	  You can also display all config items:
-
-	  nsh> cfgdata print all
-	  Name                    Len   Data
-	  macaddr                 6     0xFC 0x01 0x0B 0x45 0xA1 0x12
-	  hostname                8     myboard
-
-	  From Ken Pettit (2018-12-20).
-	* apps/examples/smp: Add dependency on SMP in Kconfig  From Masayuki
-	  Ishikawa (2018-12-25).
-	* apps/testing/ostest:  Add test for pthread-specific data.  From Gregory
-	  Nutt (2018-12-28).
-	* apps/examples/battery:  Add Battery Charger Monitor Example  From Alan
-	  Carvalho de Assis (2019-01-04).
-	* apps/system/termcurses:  Addition of termcurses libraries in
-	  apps/system/termcurses  From Ken Pettit (2019-01-05).
-	* apps/graphics/pdcurs34: Integration of termcurses into pdcurses, plus
-	  pdcurses updates for multi-thread support  From Ken Pettit (2019-01-05).
-	* [WIP] nshlib add var expansion in nsh parse  From Daniel Agar
-	  (2019-01-06).
-	* apps/system/nxplayer: Introduce CONFIG_NXPLAYER_MAINTHREAD_STACKSIZE
-	  From Masayuki Ishikawa (2019-01-07).
-	* apps/graphics/pdcurs34/nuttx and system/termcurses:  This commit fixes
-	  two issues:
-	  1. A memory corruption issue that occurs from a paste operation that
-	     would overflow the fixed buffer size for keyboard processing.
-	  2. A stall in getch() processing when there are cached keycodes in the
-	     termcurses emulation (tcurses_vt100.c)
-	  From Ken Pettit (2019-01-08).
-	* graphics/pdcurs34: This commit adds a configuration option to pdcurses
-	  to enable line-drawing character (ALTCHARSET) when using the short
-	  16-bit chtype.  This is done by limiting the characters to 7-bit ASCII
-	  values and using the 8-th bit as the A_ALTCHARSET bit.  This allows a
-	  significant RAM savings 4K - 20K depending on terminal size) while
-	  still allowing the nicer line-graphic characters for border drawing.
-	  From Ken Pettit (2019-01-08).
-	* apps/nshlib/nsh_command.c:  display built-in apps using multi-column
-	  mode like the nsh commands  From Ken Pettit (2019-01-11).
-	* apps/system/termcurses/tcurses_vt100.c: Fix an issue where the first
-	  curses 'getch()' call sometimes (usually) hangs waiting for a keypress.
-	  This bug was introduced when I fixed the keyboard 'paste' overflow
-	  error.  From Ken Pettit (2019-01-11).
-	* apps/nshlib/nsh_command.c:  In all multi-column help output, calculate
-	  an optimal column width rather than using a hard-coded width that may
-	  or may not be appropriate.  Also make the number of rows presented
-	  dependent upon the maximum width of the widest column.  From Gregory
-	  Nutt (2019-01-11).
-	* apps/nshlib/nsh_parse.c:  Fixes an error in the NSH parser.  There was
-	  a bug when executing an nsh shell script which contains a redirection.
-	  When the command in the script is executed, it sets the
-	  vtbl->np.np_redirect flag (as it should), but then doesn't restore it,
-	  leaving it set at the end of the script execution.  Then the
-	  vtbl->np.np_redirect flag is set when the 'sh' command completes,
-	  causing a restore from un-initialized variables, thus leading to a
-	  crash.  See the code snippet below for an example test case.
-
-	  Test case:
-
-	  NuttShell (NSH)
-	  nsh> mkrd -s 1024 40
-	  nsh> mkfatfs /dev/ram0
-	  nsh> mount -t vfat /dev/ram0 /tmp
-	  nsh> echo "echo 1 > /dev/null" > /tmp/test.sh
-	  nsh> cat /tmp/test.sh
-	  echo 1 > /dev/null
-	  nsh> sh /tmp/test.sh
-	  ...
-
-	  The nsh prompt doesn't get printed.  You can type a couple of commands,
-	  but then the system will crash because of bad pointers.  From Ken
-	  Pettit (2019-01-12).
-	* wireless/ieee802154/i8sak: Fixes issues related to re-running daemon.
-	  Releases lock when releasing daemon. Re-sets daemon_shutdown so that a
-	  subsequent daemon launch does not immediately return.  From Anthony
-	  Merlino (2019-01-13).
-	* NSH addroute: Adds command for setting default gateway. addroute
-	  default <ipaddr> <interface>  From Anthony Merlino (2019-01-13).
-	* apps/system/termcurses: Perform a bounds check to fix a random
-	  Termcurses crash that I haven't been able to track down.  The result of
-	  of the subtraction for priv->keycount should never be negative, but I
-	  think sometimes it is, so better to catch it and avoid a crash until I
-	  can track it down.  From Ken Pettit ? (2019-01-16).
-	* apps/system/vi:
-
-	  Bug fixes and changes to existing functionality
-
-	  1.  Deletion of last line in file using 'dd' caused infinite loop
-	      searching for 'nextline'.  Fixed.
-	  2.  Insertion of line above 1st line using 'O' caused line to be
-	      inserted on 2nd line.  Fixed.
-	  3.  Paste buffer from 'dd' was being free'd after the 'p'aste operation,
-	      preventing multiple paste opportunity.  Fixed.
-	  4.  The cursor was not being bound to the line end and was allowed to
-	      'hover' over the '\n' EOL character.  This caused weird (relative to
-	      standard vi) insertion locations and cursor movement with 'a'ppend
-	      and 'i'nsert.  Fixed.
-	  5.  The 'vi_shrinkpos' position didn't take the end of file pointer into
-	      account when calculating 'curpos', 'prevpos' variables causing
-	      weirdness when deleting things near the end of the file.  Fixed.
-	  6.  The 'yy'ank command was improperly deleting the text from the
-	      document instead of simply yanking to the paste buffer.  Fixed.
-	  7.  The 'dd'elete line function was not copying the deleted line to the
-	      paste buffer as part of the delete operation.  Fixed.
-	  8.  The bottom line of the screen was sometimes being used for document
-	      text and other times for command / find entry.  Fixed by reserving
-	      the bottom the bottom line for status / command only.
-	  9.  When scrolling up / down through a file, the cursor position was not
-	      preserved and moved further and further to the left column based on
-	      the line lengths of the lines visited.  Fixed.
-	  10. The display was being COMPLETELY redrawn with each keystroke,
-	      causing the responsiveness to be unbearable.  Fixed.  Added logic
-	      to dynamicall indicated which portions of the screen need to be
-	      updated (full display, current line to end of screen, current line
-	      only, none).
-	  11. The individual display line updates were being performed a
-	      character at a time by calling the vi_putch() function, causing slow
-	      performance, especially in telnet or USBCDC sessions where there is
-	      a lot of overhead per packet.  Fixed by calling vi_write() instead
-	      with a block of characters with breaks as needed for TAB exansion.
-	  12. The forward delete 'x' operation allowed deletion through '\n'
-	      characters causing lines to be joined.  This is different from
-	      standard vi where 'x' at the end of a line performs a delete
-	      backward operation.  Fixed.
-	  13. When in 'ex' or find sub-modes (':' or '/' bottom line modes),
-	      hitting backspace with empty text did not return the operation to
-	      command mode like it does in standard vi.  Fixed.
-	  14. Performing a 'find' opertation would only search from the current
-	      cursor position to the end of the file and did not wrap like in
-	      standard vi.  Fixed.
-	  15. Loading a file that was larger than the initial text allocation
-	      would force a call to 'vi_extendtext', marking the file as modified
-	      when in fact it hadn't even been loaded yet.  Fixed.
-	  16. Combined vi_insert_mode and vi_replace_mode into a single function
-	      to save code space since they are nearly identical routines.
-	  17. In command mode, backspace was deleting characters which is different
-	      from standard vi.  Backspace in command mode normally simply moves
-	      the cursor left / to the previous line.  Fixed.
-	  18. Added code to handle boundary conditions when the file is new and
-	      commands are applied to an empty file.
-	  19. Fixed vi_shrinktext so it doesn't allocate a zero-length buffer when
-	      the last character in the file is deleted.
-	  20. The 'x' command was not copying to the paste buffer.  Fixed.
-	  21. Fixed parsecolon routine to properly deal with ":wq" command
-	      sequence.
-
-	  New feature additions
-
-	  1.  Vi startup feature to prepend the current working directory to the
-	      supplied filename if it does not start with '/' absolute path
-	      specifier.  This allows editing files in the current directory
-	      without needing to fully qualify the filename.
-	  2.  Standard '~' empty screen line characters for proper identification
-	      of empty '\n' only lines at the end of the file.
-	  3.  Moving into insert or append mode now prints '--INSERT--' in the
-	      status line and clears it upon exit.
-	  4.  Integration with termcurses to detect special keystrokes and to
-	      handle terminal type differences.  Haven't yet converted all vt100
-	      print codes to termcurses equivalents.
-	  5.  Support for up, down, left, right arrows, page-up, page-down keys
-	      in command mode.
-	  6.  Added 'b' command to move cursor 'b'ack to previous word.  Honors
-	      the command repeat value for multiple word moves.
-	  7.  Added 'w' command to move cursor to next 'w'ord.  Honors the command
-	      repeat value for multiple word moves.
-	  8.  Added 'f' and 't' commands to find characters on the current line.
-	      Honors the command repeat value.
-	  9.  Added the find 'n'ext command to repeat the previous find operation.
-	  10. Added the 'H', 'M', and 'L' commands to move the cursor to top,
-	      middle and bottom of the display.
-	  11. Extended yank/paste to manage a paste buffer with character mode in
-	      addition to line mode.  Character mode allows cut / paste of
-	      individual characters or groups of characters vs. full lines.
-	  12. Added support in the 'd'elete and 'y'ank commands for character mode
-	      deletions such as 'dw', 'dfa', '2yw', etc.
-	  13. Added support in paste routine for multiple paste using command value
-	      argument.
-	  14. Added support for the 'D' and 'C' delete and change to end of line
-	      commands.
-	  15. Added support for 's'ubstitute key ('x' followed by insert mode).
-	  16. Modified yank / paste allocation scheme to avoid repeated alloc
-	      and free of paste buffer.  Uses a minimum allocation size scheme and
-	      only does free / realloc when paste does not fit.  If the paste is
-	      smaller than the current allocation and the current allocation is
-	      larger than the threshold, then the buffer is freed and a smaller
-	      buffer allocated.  Otherwise the existing buffer is used.
-	  17. Support for 'P'aste before current cursor position.
-	  18. Support for '?' reverse search mode.
-	  19. Support for 'J'oin next line with current line command.
-	  20. Printing of current row,col in status line of display.
-	  21. Command repeat '.' support for commands that modify text.
-	  22. Support in replace  / insert mode for arrow keys, PGUP / PGDN, HOME,
-	     and END.  Using these will cause the command repeat buffer to
-	     reset such that only the last text addition after a cursor movement
-	     is saved.
-	  23. Added 'X' delete previous command.
-	  24. Added "gg" go to top of document command sequence.
-	  25. Added "ZZ" save and quit command (equivalent to :wq).
-	  26. Implemented '^' goto first non-whitespace on current line, along
-	      with '+' and '-' goto first non-whitespace on next / previous line.
-	  27. Added CR / LF goto first non-whitespace on next line in command
-	      mode. From Ken Pettit (2019-01-16).
-	* apps/nshlib:  Fix buffer overrun when redirected to a file.  SAVE_SIZE must
-	  be the same as sizeof(struct serialsave_s).  From Masayuki Ishikawa
-	  (2019-01-19).

-	* apps/system/nxplayer:  Fix compile problems when audio debug is enabled.
-	  From Gregory Nutt (2019-04-23).
-	* Twm4Nx is a port of twm, Tab Window Manager (or Tom's Window Manager)
-	  version 1.0.10 to NuttX NX windows server.  No, a port is not the right
-	  word.  It is a re-design of TWM from the inside out to work with the NuttX
-	  NX server.  The name Twm4Nx reflects this legacy.  But Twm4Nx is more a
-	  homage to TWM than a port of TWM.
-
-	  The original TWM was based on X11 which provides a rich set of features.
-	  TWM provided titlebars, shaped windows, several forms of icon management,
-	  user-defined macro functions, click-to-type and pointer-driven keyboard
-	  focus, graphic contexts, and user-specified key and pointer button
-	  bindings, etc.
-
-	  Twm4Nx, on the other hand is based on the NuttX NX server which provides
-	  comparatively minimal support.  Additional drawing support comes from
-	  the NuttX NxWidgets library (which necessitated the change to C++).
-
-	  Twm4Nx is greatly stripped down and targeted on small embedded systems
-	  with minimal resources.  For example, no assumption is made about the
-	  availability of a file system; no .twmrc file is used.  Bitmaps are not
-	  used (other than for fonts).
-
-	  The TWM license is, I believe compatible with the BSD license used by
-	  NuttX.  The origin TWM license required notice of copyrights within each
-	  file and a full copy of the original license which you can find in the
-	  COPYING file within this directory.
-
-	  STATUS:
-
-	  This port was brutal.  Much TWM logic was removed because it depending on
-	  X11 features (or just because I could not understand how to use it).  The
-	  logic is partial.  A lot more needs to be done to have a complete system
-	  (hence, it is marked EXPERIMENTAL).  The kinds of things that need to
-	  done are:
-
-	  1. Update some logic that is only fragmentary for how like resizing, and
-	     menus.
-	  2. Integrate NxWidgets into the windows:  The resize menu needs a CLabel,
-	     the menus are CListBox'es, but not completely integrated, the Icon
-	     Manager needs to be a button array.
-	  3. Revist Icons.  They are windows now, but need to be compound widgets
-	     lying on the background.
-	  4. Widget events are only partially integrated.  A lot more needs to be
-	     done.  A partial change to those event system that hints at the
-	     redesign is in place but it is far from complete.  From Gregory Nutt
-	     (2019-04-25).
-	* graphics/twm4nx/src/cwindow.cxx:  Finishes first cut at window event
-	  management.    Use CNXWidgets::CButtonArry for Icon manager.  Implement
-	  button event handling.  From Gregory Nutt (2019-04-26).
-	* graphics/nxwidgets/src/cbuttonarray.cxx:  Add a method to CButtonArray
-	  that will allow us to dynamically resize the array (at the cost of losing
-	  all button labels).  From Gregory Nutt (2019-04-26).
-	* netutils/netlib/netlib_parseurl.c:  Add a  more flexible version of
-	  netlib_parsehttpurl.  This one can parse any URL, and is extensible so
-	  future improvements keep the same API.  From Sebastien Lorquet
-	  (2019-04-26).
-	* apps/graphics/twm4nx:  In order for widgets to draw the correct window or
-	  toolbar, it is necessary to get the CWidgetControl instance from the
-	  window we want to use, not to create a new instance.  From Gregory Nutt
-	  (2019-04-26).
-	* apps/graphics/twm4nx:  Finish menu-related event handling.  Extended menu
-	  handling.  Allow external application event handling using a new base
-	  class (CTwm4NxEvent).  From Gregory Nutt (2019-04-27).
-	* apps/graphics/twm4nx:  Flesh out some of the Resize logic.  Still missing
-	  the pull events needed to do the resize.  From Gregory Nutt (2019-04-27).
-	* apps/graphics/twm4nx:  Add compound widget CIconWidget.  This will
-	  eventually replace the icon Windows with widgets that can be drawn on the
-	  Background.  From Gregory Nutt (2019-04-27).
-	* apps/examples/pca9635/pca9635_main.c: fix compilation  From Mateusz
-	  Szafoni (2019-04-28).
-	* apps/netutils:  Support for the current version of cJSON  From Mateusz
-	  Szafoni (2019-04-28).
-	* apps/graphics/twm4nx:  Remove Icon Windows; replace with IconWidgets that
-	  are draw on the background.  Add CIconWidget event generation.  Add event
-	  handling logic to CIconWidget.  From Gregory Nutt (2019-04-28).
-	* apps/graphics/twm4nx:  Suppress input thread if using the VNC server.  We
-	  don't need to catch input from keyboard or mouse devices in that case;
-	  those inputs will be injected into NX directly by the VNC server.
-	  Includes a couple of fixes from initial bring-up attempts.  From Gregory
-	  Nutt (2019-04-28).
-	* apps/netutils/netinit.  This commit removes the private network
-	  initialization logic from NSH and puts in a common location at
-	  apps/netutils/netinit.  Now that netork initialization logic can be used
-	  by applications that do not include NSH.  From Gregory Nutt (2019-04-29).
-	* apps/graphics/twm4nx:  Add options to initialize the system via
-	  boardctl() and to bring up the network using the new
-	  apps/netutils/netinit.  This latter is only necessary because VNC is
-	  being used to provide graphics.  From Gregory Nutt (2019-04-29).
-	* Many locations:  Remove references to CONFIG_DISABLE_SIGNALS.  Signals
-	  can no longer be disabled.  From Gregory Nutt (2019-04-29).
-	* apps/graphics/NxWidgets:  Fix a possible deadlock condition when waiting
-	  for window geometry data that will never come.  Fixed by re-requesting
-	  geometry data if we don't already have it.  From Gregory Nutt (2019-05-01).
-	* apps/graphics/twm4nx:  Revamp how background events are handled.  From
-	  Gregory Nutt (2019-05-01).
-	* include/graphics/nxwidgets/cwidgetcontrol.hxx:  Add handshake to
-	  getWindowHandle() to avoid returning a NULL handle.  But now Twm4Nx hangs
-	  waiting for the non-NULL handle,  From Gregory Nutt (2019-05-01).
-	* apps/graphics/twm4nx:  Fix various bugs found in bringup:  Re-order
-	  object instantiation to account for inter-object dependencies.  Correct
-	  mq_receive() buffer size.  Fix a backward comparison.
-
-	  apps/graphics/twm4nx:  Twm4Nx debug can now be separately enabled so that
-	  it does not get overwhelmed by other graphics debug output.  From Gregory
-	  Nutt (2019-05-02).
-	* apps/graphic/twm4nx:  Fix junk variable that was shadowing variable of
-	  the same name in the base CNxWidget class.  Resolves all start up crash
-	  issues.  Now I need to figure out why the host VNC client drops the
-	  connection.  From Gregory Nutt (2019-05-02).
-	* apps/netutils/libcurl4nx:  This is an initial commit libcurl4nx.  It is
-	  not complete yet, but I still wish to commit the unfinished bits to
-	  describe the roadmap, and because it is already usable.  It will be
-	  updated and fixed in the future weeks and months, certainly including
-	  POST support and later, SSL.
-
-	  Some improvements could be made by anyone.  For example, I know the main
-	  routine in perform() shall be split into several parts for readability. I
-	  apologize in advance for this kind of spaghetti code, but I was short on
-	  time to refactor it.  Also chunked HTTP transfer encoding would be a nice
-	  contribution from anyone interested. It is detected but not yet
-	  supported.  From Sebastien Lorquet (2019-05-03).
-	* graphics/twm4nx/src/cbackground.cxx:  Should set the initial background
-	  color immediately without waiting for a redraw.  From Gregory Nutt
-	  (2019-05-04).
-	* graphics/twm4nx/Kconfig:  Add configuration to disable keyboard/mouse
-	  input for testing purposes.
-
-	  graphics/twm4nx/src/ciconmgr.cxx:  Correct initial window size and
-	  position in the upper right hand corner;  Need to fill draw the button
-	  array immediately on window creation.
-
-	  graphics/twm4nx/src/cwindow.cxx:  Need to fill the toolbar initially
-	  with the widget background color.
-	  From Gregory Nutt (2019-05-04).
-	* apps/graphics/NxWidgets:  CNxTkWindow, CNxWindow, CNxServer:  Add support
-	  to create RAM backed windows.  From Gregory Nutt (2019-05-04).
-	* apps/graphics/twm4nx:  IconMgr window now comes up correctly.  Need to
-	  revisit window width setup.  All windows are now created as RAM backed
-	  windows.  From Gregory Nutt (2019-05-04).
-	* apps/graphics/twm4nx:  Add option to use touchscreen instead of mouse
-	  input.  Add option to use the touchscreen with no keyboard.  From Gregory
-	  Nutt (2019-05-04).
-	* graphics/twm4nx/src/cbackground.cxx:  Add logic to handle polling for
-	  background icon events.
-
-	  graphics/twm4nx/src/window.cxx:  Add flags to CWindow initializer to
-	  support customization of toolbar buttons and other window properties.
-	  Add framework to handle toolbar button presses.  Window minimization
-	  (aka, iconification) does not work.
-
-	  graphics/twm4nx/src/input.cxx:  Add support to scaling touchscreen.  Not
-	  needed for the current testing because the touchscreen naturally matches
-	  the display size.  But will be needed, along with calibration screen, in
-	  the future.  From Gregory Nutt (2019-05-05).
-	* apps/graphics/twm4nx:  Add logic to hide the window when it is iconified
-	  and restore the window when it is de-iconfied.  Iconification works,
-	  de-iconification does not.  From Gregory Nutt (2019-05-05).
-	* apps/graphics/twm4nx:  Try to improve icon text spacing.  Not noticeably
-	  better, however.  Split long icon title on two lines below the icon
-	  image.  Both iconification and de-iconification now work.  From Gregory
-	  Nutt (2019-05-06).
-	* apps/graphics/twm4nx:  Add initial support for the main menu.  The main
-	  menu will come up when a left click is performed on the background.  The
-	  main menu is used for starting applications.  The adds the CMainMenu
-	  class that implements the main menu and an IApplication interface class
-	  the provides th template for how any external C++ application can add
-	  itself to the Main Menu.  Still missing is the logic that responds to the
-	  menu item selection and sends the event to the Main Menu as well as the
-	  logic in the Main Menu that handles the event and either brings up a
-	  sub-menu or starts and application.  From Gregory Nutt (2019-05-06).
-	* apps/graphics/twm4nx:  Replace most usage of NUL-terminated C strings
-	  with NXWidgets::CNxString.  From Gregory Nutt (2019-05-06).
-	* apps/graphics/twm4nx:  Exploit the new feature to create hidden windows.
-	  This cleans up some brief window startup anomalies.  Also fixes an
-	  initialization error in CMenus.  From Gregory Nutt (2019-05-07).
-	* apps/graphics/twm4nx:  First cut at redesigned dragging logic.  Window
-	  dragging now sort of works in an unreliable hurky-jerkky way.  More to be
-	  done.  From Gregory Nutt (2019-05-07).
-	* apps/graphics/twm4nx:  Extend the IEventTaps interfaces and user's
-	  thereof to better handle the cases when dragging where the mouse position
-	  gets ahead of the window updates and the reported mouse position lies not
-	  in the toolbar window, but in the main window or even outside of the
-	  window.  From Gregory Nutt (2019-05-07).
-	* apps/graphics/twm4nx:  Add initial files to support an NxTerm
-	  application.  On this initial commit, these are just the NxWM NxTerm
-	  files with some renaming.  These are not finished and have not yet been
-	  hooked into the build system.  From Gregory Nutt (2019-05-08).
-	* apps/graphics/nxwidgets:  CWidgetControl::handleLeftClick now returns a
-	  value to indicate if the click was actually processed or not.
-	  CWidgetControl::pollMouseEvents:  Correct return value.  From Gregory
-	  Nutt (2019-05-08).
-	* apps/graphics/twm4nx:  CBackground::event():  Implement logic to handle a
-	  left click on the background and to bring up the main Menu.
-	  CWindowEvent: Extend message to distinguish between keyboard and mouse
-	  input.  Mouse position and buttons now accompany the mouse input data.
-	  CMenus: Add methods to query and control the visibility of the menu.
-	  With these changes, the main menu appears when any location on the
-	  background not occupied by an icon is clicked.  From Gregory Nutt
-	  (2019-05-08).
-	* apps/graphics/twm4nx:  CMenus now uses CWindows, rather that raw NX
-	  windows.  This rippled through to many other things due to conflicts
-	  between NUL-terminated C strings and NXWidgets::CNxStrings.  From Gregory
-	  Nutt (2019-05-08).
-	* apps/graphics/twm4nx:  CWindow: Add a global function that can be used to
-	  determine the minimum width of a window.  If the window is set to a width
-	  smaller than this, then toolbar items will overlap and the toolbar will
-	  be corrupted.  This is a global function (rather than a method of
-	  CWindow) because in some cases, this minimum width must be known before
-	  the window is created.  From Gregory Nutt (2019-05-08).
-	* apps/graphics/nxwidgets:  Add methods to all windows to query if a window
-	  is visible or hidden.  From Gregory Nutt (2019-05-09).
-	* apps/graphics/twm4nx:  Better integrate menus and iconification:  Bring-up
-	  up a menu is like de-iconifcation, except there is no icon to be erases;
-	  taking down a menu is like iconification except that there is no icon to
-	  present.
-
-	  apps/graphics/twm4nx:  Use NxWidgets methods which work in all contexts
-	  instead of trying to come up with a way to know if a window is displayed
-	  through complex flags.
-
-	  apps/graphics/twm4nx:  Add logic so that the main menu is placed at (or
-	  near) the position where the background was clicked.
-
-	  apps/graphics/twm4nx:  In resize operation, don't let window get narrower
-	  than the minimum toolbar width.
-
-	  apps/graphics/twm4nx:  The Icon Manager now adds a Main Menu entry that
-	  will de-iconify the Icon Manager or raise to the top of the hierarchy if
-	  not iconfified.  This is useful when there are many open windows.
-	  From Gregory Nutt (2019-05-09).
-	* apps/graphics/twm4nx:  Use button array vs list box for menus.
-
-	  apps/graphics/twm4nx:  Correct an error in how menu windows are created.
-	  From Gregory Nutt (2019-05-10).
-	* apps/graphics/twm4nx:  Add a 'Desktop' item to the main menu that will
-	  iconify all windows and menus and just show the open desktop.
-
-	  apps/graphics/twm4nx:  Add more controls for the events that will be
-	  generated on basic window redraw, mouse/keyboard input, and keyboard input.
-
-	  apps/graphics/twm4nx:  Add logic to support distribution of gnereric
-	  application window events.
-
-	  apps/graphics/twm4nx:  Window events are now communicated properly to the
-	  application-specific event handler.  Menus now seem to be receiving
-	  events and working well.
-	  From Gregory Nutt (2019-05-10).
-	* apps/system/spi:  I needed a small test tool for spi in the style of the
-	  I2C tool, but I didn't see one so I've hacked one out of the I2C tool
-	  source.  From Dave Marples (2019-05-10).
-	* apps/graphics/twm4nx:  Add new logic to place an icon at a reasonable
-	  spot on the background.  From Gregory Nutt (2019-05-11).
-	* apps/graphics/twm4nx:  Modify how applications register with the main
-	  menu.  Add logic to support all possible menu selection notification
-	  methods:  By putting up a sub-menu, by starting an application, or be
-	  sending an event.  From Gregory Nutt (2019-05-11).
-	* apps/graphics/twm4nx:  Add an IApplicationFactory interface.  From
-	  Gregory Nutt (2019-05-11).
-	* apps/graphics/twm4nx:  This commit incorporates the NxTerm window hosting
-	  NSH.  This is just code complete and just compiles with no errors.  The
-	  NxTerm item does not appear in the Main Menu, however, selecting the menu
-	  item does not yet bring up the NxTerm window.
-
-	  apps/graphics/twm4nx:  Clean up some logic associated with use of
-	  multiple Icon Managers.  From Gregory Nutt (2019-05-12).
-	* apps/graphics/twm4nx: Add missing event generation logic when a window is
-	  closed.
-
-	  apps/graphics/twm4nx:  Fix a couple of errors in the unused resize
-	  logic:  It was not hiding the resize menu tso it appeared as a artifact
-	  in the upplr left hand corner.  Was calling setSize() on the window
-	  instead of getSize().  That was causing errors because the size being set
-	  was uninitialized.  From Gregory Nutt (2019-05-12).
-	* apps/graphics/NXWidgets/:  NXWidgets::CNxWidgets:  Fix some issues with
-	  returned values.  On setting the widget size or position, it was
-	  returning false if there was no change in size or position.  Many places
-	  in the code were treating the false return value as an error.  From
-	  Gregory Nutt (2019-05-12).
-	* apps/graphics/twm4nx:  Simpify application startup.
-
-	  apps/graphics/twm4nx:  Various fixes to get the NxTerm window to come
-	  up properly.  It does now come up okay, but the system basically loses
-	  its mind thereafter.  Looks good until some buttons are pressed.
-	  From Gregory Nutt (2019-05-12).
-	* apps/graphics/twm4nx:  Fix several errors associated with the NxTerm
-	  buttons.  Most changes involved fixing crashes with the exit button is
-	  pressed.  Now the NxTerm windows behave well.  However, they are not
-	  receiving console input so there is still more to be done.
-
-	  apps/graphics/twm4nx:  Fix error in placement of icons on the desktop
-	  From Gregory Nutt (2019-05-13).
-	* apps/graphics/twm4nx:  Icons can now be moved, but there are artifacts:
-	  Need to erase the old icon region on the background before drawing the
-	  new icon image during the move.  From Gregory Nutt (2019-05-13).
-	* apps/graphics/twm4nx:  When moving icons, erase the old icon image before
-	  drawing the new one.
-
-	  apps/graphics/twm4nx:  Add logic to detect collisions with reserved
-	  regions in the background or with other icons when moving an icon on
-	  the desktop.
-	  From Gregory Nutt (2019-05-14).
-	* apps/graphics/twm4nx:  Correct logic in Icon Manager for the case where
-	  the number of windows causes the Icon Manager to increase in size by one
-	  row.
-
-	  apps/graphics/twm4nx:  Fix an error in event notification sent by the
-	  Icon Manager when a window is selected.
-
-	  apps/graphics/twm4nx:  In the Icon Manager, do not use the window name to
-	  identify which button press corresponds to which Window.  Window names
-	  are not unique.  Instead, it now keeps track of which row x column was
-	  assigned to the window name.  That row x column uniquely associates a
-	  window with a button and does not depend on the window name in any way.
-	  From Gregory Nutt (2019-05-14).
-	* apps/graphics/nxwidgets/src/cbuttonarray.cxx:  Correct an error
-	  CButtonArray.  Was not correctly resizing the widget when the dimensions
-	  of the button array changed.  From Gregory Nutt (2019-05-15).
-	* apps/graphics/twm4nx:  This is a complete redesign of the CResize class.
-	  Only partially functional on initial commit.  Initial testing is mixed.
-	  The resize window appears, but nothing else good happens.  No hardfaults
-	  though.
-
-	  apps/graphics/twm4nx:  Forgot to install the IEventTap instance.  Now
-	  resizing kind of works, but I can't get out of it!  There is a basic
-	  problem in the window needs to be updated for the new size and there is
-	  no mechanism in place to do that (at least not with RAM backed windows).
-
-	  apps/graphics/twm4nx:  Fix a bad width calculation.
-	  From Gregory Nutt (2019-05-15).
-	* apps/graphics/twm4nx:  Fix routing of redraw events.
-
-	  apps/graphics/twm4nx:  Other toolbar buttons need to be disabled while
-	  resizing.  Lots of problems if you decide to iconify or exit while
-	  resizing.  CResize now disables all buttons except for the RESIZE button
-	  while resizing.
-
-	  apps/graphics/twm4nx:  Add an event and logic to support notification of
-	  changes in the size of a window to NxTerm.
-
-	  apps/graphics/twm4nx:  Correct the maximum size of a message.  Recent
-	  changes caused message send failures because a message exceed that
-	  previous maximum size.  From Gregory Nutt (2019-05-16).
-	* Various updates to adapt to change in boardctl() interface.  From Gregory
-	  Nutt (2019-05-16).
-	* apps/graphics/twm4nx:  During resizing, when the tool bar is drawn, the
-	  toolbar background must be redraw before the buttons and title are
-	  redrawn.  From Gregory Nutt (2019-05-16).
-	* apps/graphics/nxglyphs:  Add a new resize cursor image.
-	  apps/graphics/twm4nx:  Use new resize cursor image.  From Gregory Nutt
-	  (2019-05-17).
-	* apps/graphics/twm4ndx:  Compile out cursor support if we are using a
-	  mouse  From Gregory Nutt (2019-05-17).
-
-7.31 2019-07-21 Gregory Nutt <gnutt@nuttx.org>
-
-	* Remove some cases in Kconfig files of 'comment' with 'depends on'.  That
-	  is probably a good practice.  I removed these because (1) is not done
-	  elsewhere so it is just an inconsistency, and (2) the HTML generation
-	  tool at nuttx/tools/kconfig2html.c would need to be extended to parse
-	  that case.  I don't have time to do that now.  From Gregory Nutt
-	  (2019-05-19).
-	* This change adds a calibration screen to Twm4Nx.  In addition to the
-	  Calibration screen port from NxWM, this required extensions to the event
-	  handling logic to support (1) receiving raw, uncalibrated touchscreen
-	  inputs, (2) shutting down of externally controlled windows.  From Gregory
-	  Nutt (2019-05-20).
-	* apps/graphics/twm4nx:  Move application-related files into different
-	  directories to separate them from the core Twm4Nx files.  From Gregory
-	  Nutt (2019-05-20).
-	* apps/graphics/twm4ndx:  Compile out cursor support if we are using a
-	  mouse.  From Gregory Nutt (2019-05-20).
-	* apps/graphics/twm4nx:  Fix an uninitialized variable that was causing
-	  toolbar buttons to randomly come up enabled or disabled.  Remove some
-	  unused event definitions.  From Gregory Nutt (2019-05-20).
-	* apps/graphics/twm4nx:  Fix a calibration screen startup issue.  Make an
-	  initial calibration screen optional.  From Gregory Nutt (2019-05-20).
-	* apps/nshlib:  Fix all places where cle() and readline() are used.
-	  readline() returns EOF on a failure.  cle() returns a negated errno
-	  value.  Checking only for EOF causes failures to be missed (and infinite
-	  loops ensuing).  From Valmantas Paliksa (2019-05-21).
-	* Add an alternative COMPONTEMPORARY theme.  Still has some artifacts on
-	  the display.  From Gregory Nutt (2019-05-21).
-	* apps/graphics/twm4nx:  Use custom CWidgetStyle to force Icon background
-	  to match selected desktop background.  From Gregory Nutt (2019-05-21).
-	* apps/graphics/nxglyphs:  Add more modern looking button images for the
-	  Twm4Nx CONTEMPORARY theme.  From Gregory Nutt (2019-05-21).
-	* apps/graphics/twm4nx:  Add some definitions to support Themes.
-	  Background image is now optional.  From Gregory Nutt (2019-05-21).
-	* apps/graphics/twm4nx: Add a configuration option to control the number of
-	  buttons in one column of the Icon Manager.  The Icon Manager no longer
-	  relies the default window width; now it determines a preferred window
-	  width based primarily on the font size.  From Gregory Nutt (2019-05-21).
-	* apps/:  Removed all references to CONFIG_DISABLE_POLL.  The standard
-	  POSIX poll() can not longer be disabled.  From Gregory Nutt (2019-05-21).
-	* apps/graphics/twm4nx:  Revise logic to detect clicks on the background
-	  image.  The original implementation had some side effects.  From Gregory
-	  Nutt (2019-05-23).
-	* apps/graphics/twm4nx:  Remove some remaining, unused stuff from TWM that
-	  was never used.  Menus need to close after the 'terminal' selection is
-	  made.  Otherwise, the menu can become buried under a newly open menu and
-	  not easily recovered.  From Gregory Nutt (2019-05-23).
-	* apps/graphics/twm4ndx:  Add a 'critical' bit to the eventID.  While
-	  resizing, all events will be ignore except those marked critical.
-	* apps/graphics/twm4nx:  CBackground now brings up the main menu if the
-	  background image is clicked.  This makes the behavior the same across all
-	  of the background except when an icon is clicked.  From Gregory Nutt
-	  (2019-05-23).
-	* apps/graphics/twm4nx:  Fix a bug in placement of icons on the desktop.
-	  When many windows are displayed, a bug in the looping logic could cause
-	  an infinite loop.  From Gregory Nutt (2019-05-26).
-	* apps/graphics/twm4nx:  Fix some errors found when enabling NX keyboard
-	  support. The most important being that the mouse and keyboard drivers
-	  need to be opened non-blocking.  From Gregory Nutt (2019-05-26).
-	* apps/graphics/twm4nx/README.txt:  Add an overview of how to create Twm4Nx
-	  applications.  From Gregory Nutt (2019-05-28).
-	* apps/graphics/slcd:  Adds a CSLcd class that will generate graphic
-	  simulated segments of an SLCD display.  From Gregory Nutt (2019-05-31).
-	* apps/graphics/tmw4nx and apps/graphics/slcd:  Add a CClock class that
-	  implements the Twm4Nx digital clock based on the CSLcd simulated SLCD
-	  segments.  From Gregory Nutt (2019-06-01).
-	* apps/graphics/slcd:  Improve the representation of '1', 'l', and 'I'.
-	  From Gregory Nutt (2019-06-01).
-	* netutils/telnetd/telnetd_daemon.c:  Fix another C89 violation that caused
-	  the ez80 build to fail.  From Gregory Nutt (2019-06-03).
-	* nshlib/nsh_parse.c:  Fix a warning about an uninitialized variable from
-	  the ZDS-II compiler.  From Gregory Nutt (2019-06-03).
-	* apps/netutils/netinit:  MAC address configuration was represented by type
-	  long long.  That is a problem for architectures that do not support type
-	  long long.  Replaces by two long configuration items.  From Gregory Nutt
-	  (2019-06-03).
-	* apps/nshlib/nsh_ddcmd.c:  Seemingly nonsense change but somehow works
-	  around a compilation error using the ZDS-II toolchain.  It was claiming
-	  that vtbl was undefined indd_outfopen().  From Gregory Nutt (2019-06-03).
-	* apps/netutils/json:  Removed.  Replaced with apps/netutils/cjson.  From
-	  Gregory Nutt (2019-06-03).
-	* industry/abnt_codi, include/industry/abnt_code.h, examples.abntcodi:
-	  Adds support for ABNT CODI library.  This is an energy meter protocol
-	  used in Brazil.  From Alan Carvalho de Assis (2019-06-15).
-	* apps/wireless/gs2200m:  Add usrsock daemon for Tilt GS2200M Wi-Fi module
-	  From Masayuki Ishikawa (2019-06-18).
-	* apps/industry: Add .gitignore for Kconfig  From Masayuki Ishikawa
-	  (2019-06-28).
-	* apps/examples/webserver: Fix to compile with
-	  CONFIG_NETUTILS_HTTPD_SENDFILE=y.  Also some configs such as
-	  CONFIG_NETUTILS_HTTPDFILESTATS can be selected by menuconfig.  From
-	  Masayuki Ishikawa (2019-07-03).
-	* netutils/webserver: Add mp3 mime type to httpd.c  From Masayuki Ishikawa
-	  (2019-07-04).
-	* netutils/webserver: Add directory listing to httpd  From Masayuki
-	  Ishikawa (2019-07-05).
-	* netutils/webserver:  Add web server info based on uname()  From Masayuki
-	  Ishikawa (2019-07-05).
-	* netutils/webserver: Fix directory listing containing period in name  From
-	  Masayuki Ishikawa (2019-07-06).
-	* apps/netutils/cjson/Kconfig:  stdio floating point support required.
-	  cJSON requires floating point support in printf (specifically the 'g'

-	* wireless/gs2200m: Add udp support to gs2200m_main.c.  From Masayuki
-	  Ishikawa (2019-07-25).
-	* netutils/dhcpd:  Fixes bug where hwaddr was being used instead of
-	  ipaddr in the ARP update.  This bug seems to have been introduced 3
-	  years ago during a rewrite to remove a direct OS call to arp.  I'm not
-	  sure how others have not run into issues with this.  The behavior I
-	  was observing was that the DHCPD would go to offer an IP address, but
-	  then send a ARP request for the IP instead because it didn't know
-	  where to send the data.  From Anthony Merlino (2019-07-26).
-	* I8sak improvements:
-	  - wireless/ieee802154: Adds support for getting/setting maxretries and
-	    promsicuous mode from i8sak
-	  - wireless/ieee802154/i8sak: Fixes a build warning and handles a few
-	    cases where a fault can occur due to not catching missing
-	    arguments.  From Anthony Merlino (2019-07-26).
-	* apps/netutils/netinit/netinit.c:  Improve cleanup, removing 1 of 2
-	  warnings.  Unhook PHY notification signal handler when cleaning up, if
-	  an error occurs after the signal handler is put into place.  From
-	  Nathan Hartman (2019-07-26).
-	* apps/examples/webserver/webserver_main.c:  Init network & run forever
-	  only if not builtin app.  Infer from CONFIG_NSH_BUILTIN_APPS if we are
-	  a NSH built-in app or not. If built-in app (CONFIG_NSH_BUILTIN_APPS
-	  defined) then we assume network is initialized prior to webserver
-	  starting and we exit on webserver failure. If running standalone
-	  (CONFIG_NSH_BUILTIN_APPS is undefined) then behavior is unchanged:
-	  webserver initializes network and runs forever.  From Nathan Hartman
-	  (2019-07-26).
-	* apps/nshlib/nsh_fsutils.c:  As noted by David S. Alessio, 'cat' should
-	  not output any additional newline at the end of the cat'ed file
-	  content.  This was done to assure that the NSH prompt was presented on
-	  a new line.  However, that is not the correct behavior of 'cat' per
-	  the IEEE std:  "The standard output shall contain the sequence of
-	  bytes read from the input files. Nothing else shall be written to the
-	  standard output."  Reference:
-	  https://pubs.opengroup.org/onlinepubs/009695399/utilities/cat.html.
-	  This commit changes the function nsh_catfile() which underlies the
-	  'cat' command and well as other NSH commands.  Although this is the
-	  correct behavior for 'cat' it may not be the correct behavior for
-	  other commands implemented via nsh_catfile().  That remains to be
-	  determined.  From Gregory Nutt (2019-07-29).
-	* wireless/gs2200m:  Add DHCP client handling in ioctl_request()  From
-	  Masayuki Ishikawa (2019-07-30).

-	  so that Wireshark doesn't try to validate it.  From Anthony Merlino
-	  (2019-08-10).
-	* wireless/ieee802154/i8sak:  Adds support for energy scan result
-	  printout.  From Anthony Merlino (2019-08-13).
-	* i8sak:  Fixes conversion from extended address to IPv6 address.  From
-	  Anthony Merlino (2019-08-13).
-	* netutils/dhcpc:  Add host name support to dhcp client  From Masayuki
-	  Ishikawa (2019-08-14).
-	* Bugfix/i2ctool dev clobbers slave config
-	  - friendlier I2C "knock-knock" uses only read request.  While many I2C
-	    slave devices have multiple indexed registers, some have only one
-	    register and it's not indexed.  For example, the I2C bus switch
-	    TCA9548A has only a Control Register, attempting to index to
-	    "Reg[0]" alters its contents to 0x00 disabling all subordinate
-	    buses.  This patch fixes that problem by simply trying to read
-	    something/anything from the slave.  This also helps coax out slaves
-	    with register files that start from a higher index, i.e. the
-	    AT24CS0x, FLASH chips with a UUID that appears as a 2nd I2C slave at
-	    (address+8), report their serial number at Reg[80]-Reg[8F] and will
-	    NAK a read of Reg[0].
-	  - modify get/set to prevent write of reg index if not specified  From
-	  David Alessio (2019-08-20).
-	* Move apps/builtins/builtin_forindex.c to nuttx/libs/libc/builtin since
-	  it is required by kernel logic as well.  Other changes account for
-	  movement of builtin.h from nuttx/include/nuttx/binfmt/built.h to
-	  nuttx/include/lib/builtin.h.  From Gregory Nutt (2019-08-23).
-	* Makefile:  Added support for application-specific export target.  Used
-	  by nuttx/tools/mkexport.sh.  From Pavel Pisa (2019-08-30).
-	* wireless/gs2200m/gs2200m_main.c:  ioctl_request() supports
-	  SIOCGIFHWADDR.  From Masayuki Ishikawa (2019-09-02).

-	* import/Makefile's:  Remove symbol table generation from imports/Makefile
-	  to avoid the confusion with the official method.  From Xiang Xiao
-	  (2019-10-01).
-	* examples/romfs:  Remove romfs_testdir.h.  That file is regenerated
-	  whenever the example is built and so should not be in the repository.
-	  From Gregory Nutt (2019-10-01).
-	* Remove the duplicated build script files from apps/impor/tools.
-	  These will now be copied from nuttx/tools when the export package is

-	* apps/Makefile:  Make libapps overwritable.  From Xiang Xiao (2019-10-03).
-	* CONFIG_BUILD_LOADABLE:  Check the kernel function callable by BUILD_KERNEL
-	  instead of BUILD_LOADABLE since BUILD_LOADABLE could be turned on even
-	  with BUILD_FLAT.  From Xiang Xiao (2019-10-03).
-	* Clean up Makefile under apps folder no functional changes.  From Xiang
-	  Xiao (2019-10-04).
-	* fsutils/passwd/passwd_lock.c:  Use named semaphore by checking

-	  Xiao (2019-10-04).
-	* system/lzf/lzf_main.c: Check the protection by CONFIG_SYSTEM_LZF !=
-	  CONFIG_m (not elf binary) instead of CONFIG_KERNEL_BUILD.  From Xiang
-	  Xiao (2019-10-04).
-	* Fix typo error in testing/cxxtest.  From Xiang Xiao (2019-10-04).
-	* Application.mk:  Correct an error in PATH usage.  Use of toolchain

-	* apps/;  Change space to tab and help to ---help--- in Kconfig files.
-	  From Xiang Xiao (2019-10-05).
-	* Some improvements to netutils/cjson and testing/unity
-	  - netutils/cjson/Makefile: fix the error when creating Make.dep
-	  - testing/unity/Makefile: fix the error when creating Make.dep
-	  - include/.gitignore: ignore cJSON headers
-	  - netutils/cjson/Kconfig: update default version to 1.7.12. Previous

-	* Application.mk and main.c files:  Change builtin's entry point from
-	  main to xxx_main by macro expansion.  This change make the entry point
-	  fully compliant with POSIX/ANSI standard.  From Xiang Xiao (2019-10-06).
-	* apps.:  Remove the inappropriate NSH_BUILTIN_APPS coupling
-	  1. Check NSH_NETINIT for self network initialization
-	  2. Check NSH_ARCHINIT for sel arch specific initialization
-	  3. Always show help regardless of NSH_BUILTIN_APPS
-	  4. Loop forever regardless of NSH_BUILTIN_APPS, user could:
-	  a.change the default behavior by the command line argument
-	  b.or ctrl+c to break out the loop  From Xiang Xiao (2019-10-07).
-	* apps/system/composite:  Remove usb serial loopback test code we can
-	  achieve the same effect by cat or dd command.  From Xiang Xiao

-	  - friendlier I2C "knock-knock" uses only read request.  While many I2C slave
-	    devices have multiple indexed registers, some have only one register and it's
-	    not indexed.  For example, the I2C bus switch TCA9548A has only a Control

-	    report their serial number at Reg[80]-Reg[8F] and will NAK a read of Reg[0].
-	  - modify get/set to prevent write of reg index if not specified
-	  - add 'dump' command to issue a single transaction to retrieve multiple bytes
-	    from an I2C slave and register/offset.
-	  - use NuttX' isprint()
-	  - refactor to reduce coupling, hexdump only needs outstream  From David Alessio

-	* apps/system/i2c:  Fix up some complaints from nxstyle.  From Gregory Nutt
-	  (2019-10-15).
-	* Makefiles:  This reverts part of a previous change.  This restores 'conditional'
-	  inclusion of TOPDIR/Make.defs.  Otherwise all make targets fail if the board has
-	  not been configured.  That is okay most of the time, but not for things like
-	  clean and distclean which should not depend on being configured.  From Gregory

-	  Nutt (2019-10-19).
-	* apps/nshlib/nsh_fscmds.c:  The NSH mkrd command was in violation of the NuttX
-	  portable POSIX interface.  it was calling the internal OS function
-	  ramdisk_register() directly.  No only is this a violation of the interface
-	  specification, but also prevents use of mkrd in PROTECTED or KERNEL buils.
-	  With this change, the NSH mkrd command now used the BOARDIOC_MKRD boardctl()
-	  command.  This command is available in all build modes.  The effect of this
-	  change is to move the hear of the NSH mkrd command into to OS and provide
-	  user-space access via boardctl().  From Gregory Nutt (2019-10-26).
-	* apps/examples/mount:  Replace illegal call to ramdisk_register() with a call to
-	  boardctl(BOARDIOC_MKRD).  From Gregory Nutt (2019-10-26).
-	* apps/nshlib/Kconfig and examples/mount/Kconfig:  Automatically select
-	  CONFIG_DRVR_MKRD is it is needed by the configuration.  From Gregory Nutt
-	  (2019-10-26).
-	* apps/nshlib:  Tighten up some of the conditional logic for mkrd.  From Gregory
-	  Nutt (2019-10-26).
-	* nshlib/nsh_romfsetc.c and graphics/traveler/trv_romfs.c:  Replace direct calls
-	  to romdisk_register() with indirect calls via boardioctl(BOARDIOC_ROMDISK).
-	  This not only fixes the violation of the portable POSIX OS interface, but also
-	  permits use of ROM disks in PROTECTED and KERNEL modes.  There are still
-	  multiple illegal calls to romdisk_register() from code under apps/examples.
-	  These all must also be converted to use boardioctl(BOARDIOC_ROMDISK) someday.
-	  From Gregory Nutt (2019-10-26).
-	* Makefile: Fix warning: jobserver unavailable: using -j1.  Add '+' to parent make
-	  rule.  From Xiang Xiao (2019-10-29).
-	* apps/nshlib/nsh.h:  nsh: Remove the redundant check for netcmd.  Checking
-	  FS_PROCFS and FS_PROCFS_EXCLUDE_NET is enough and make the type of network
-	  device could be shown by ifconfig.  From Xiang Xiao (2019-11-03).
-	* apps/nshlib: Add rptun cmd for boot remote core.  From ligd (2019-11-03).

-	  data and list it on the NSH console.  From Alin Jerpelea (2019-11-04).
-	* apps/examples/charger:  Simple charger example that will display on the console
-	  voltage and current values.  From Alin Jerpelea (2019-11-04).
-	* apps/nshlib:  Add new NSH command, 'pmconfig'.  From ligd (2019-11-04).
-	* apps/nshlib/README.txt:  Update README to at least mention the new pmconfig
-	  command.  From Gregory Nutt (2019-11-04).
-	* netutils/netlib/netlib_getarptab.c:  Do not initialize response buffer, it is
-	  write-only.  Also add a check to assure that the sequence number in the response
-	  is the same as the sequence number in the request.  From Gregory Nutt
-	  (2019-11-04).
-	* apps/system/cle/cle.c:  This change modifies the cle to use the streams file
-	  interface more consistently and has removed the observed race conditions.  It
-	  was previously a mix of streams and fileio.  It also simplifies the VT100 cursor
-	  position handling.  From Dave Marples (2019-11-04).
-	* apps/netutils/netlib/netlib_getarptab.c:  Fix typos in comments.  From Gregory
-	  Nutt (2019-11-04).
-	* apps/system/cu/cu_main.c: (1) Fix early exit.  getc(stdin) can return 0 the
-	  first time around.  (2) Set optind to zero.  getopt() was being left in a bad
-	  state, causing parsing errors on second use.  (3) Fix priority of cu_listen().
-	  (4) Add support for -h.  From David Alessio (2019-11-05).
-	* netutils/netlib/netlib_getarptab.c:  Per an old Linux Journal article, the
-	  nl_pid fild of struct sockaddr_nl should be set to the PID of the task that
-	  created the Netlink socket.  Also fixes a warning.  From Gregory Nutt
-	  (2019-11-07).
-	* nshlib/Kconfig:  Add missing NSH_DISABLE_DMESG, typos.  From Juha Niskanen
-	  (2019-11-08).
