Subject [Announce] Apache Portable Runtime 1.3.0 Released
Date Wed, 04 Jun 2008 18:32:02 GMT
    Apache Portable Runtime 1.3.0 Released

    The Apache Software Foundation and the Apache Portable Runtime
    Project are proud to announce the General Availability of
    version 1.3.0 of the APR Apache Portable Runtime library.

    The Project further announces the General Availability of APR-util
    version 1.3.0, the companion Apache Portable Utility library.  The
    original APR-iconv version 1.2.1 release, an alternative portable
    implementation of the 'iconv' library, remains current.

    APR is available for download from:

      http://apr.apache.org/download.cgi

    This version of APR is principally a bug fix release, including
    fixes for specific platforms' configuration, feature detection,
    and run time behavior.  Most developers are encouraged to adopt
    the latest APR 1.x version to ensure the most comprehensive
    support and access to the latest features and enhancements.

    The mission of the Apache Portable Runtime Project is to create
    and maintain software libraries that provide a predictable and
    consistent interface to underlying platform-specific
    implementations. The primary goal is to provide an API to
    which software developers may code and be assured of predictable
    if not identical behavior regardless of the platform on which
    their software is built, relieving them of the need to code
    special-case conditions to work around or take advantage of
    platform-specific deficiencies or features.

    APR and its companion libraries are implemented entirely in C
    and provide a common programming interface across a wide variety
    of operating system platforms without sacrificing performance.
    Currently supported platforms include:

      UNIX variants
      Windows
      Netware
      Mac OS X
      OS/2

    To give a brief overview, the primary core
    subsystems of APR 1.3 include the following:

      Atomic operations
      Dynamic Shared Object loading
      File I/O
      Locks (mutexes, condition variables, etc)
      Memory management (high performance allocators)
      Memory-mapped files
      Multicast Sockets
      Network I/O
      Shared memory
      Thread and Process management
      Various data structures (tables, hashes, priority queues, etc)

    For a more complete list, please refer to the following URLs:

      http://apr.apache.org/docs/apr-util/modules.html

    Users of APR 0.9 should be aware that migrating to the APR 1.x
    programming interfaces may require some adjustments; APR 1.x is
    neither source nor binary compatible with earlier APR 0.9 releases.
    Users of APR 1.x can expect consistent interfaces and binary backwards
    compatibility throughout the entire APR 1.x release cycle, as defined
    in our versioning rules:

      http://apr.apache.org/versioning.html

    APR is already used extensively by the Apache HTTP Server
    version 2 and the Subversion revision control system, to
    name but a few.  We list all known projects using APR at
    http://apr.apache.org/projects.html -- so please let us know
    if you find our libraries useful in your own projects!
