Subject [ANNOUNCEMENT] Apache Logging log4j 2.0-beta3 released
Date Thu, 15 Nov 2012 07:12:03 GMT
The Apache Logging team is pleased to announce the Apache log4j 2.0-beta3 release!

Apache log4j is a well known framework for logging application behavior. Log4j 2 is an upgrade
Log4j that provides significant improvements over its predecessor, Log4j 1.x, and provides

many of the improvements available in Logback while fixing some inherent problems in Logback's


This is the fifth release of Log4j 2 and is being made available to encourage use and feedback
from the community\\

Changes in this version include:

New features:
o LOG4J2-28:  Added PropertiesRewritePolicy and ability to define properties on a Logger.

o LOG4J2-55:  Added ability to configure from an InputSource. 

Fixed Bugs:
o LOG4J2-108:  Fix NullPointerException in ClassLoaderContextSelector when no class is returned
        the SecurityManager. 
o LOG4J2-107:  PatternParser was not properly handling adjacent nested options 
o LOG4J2-95:  Add support for loading plugins inside the OSGi bundle. 
o LOG4J2-103:  The LogEvent was wrapping a ThrowableProxy with another ThrowableProxy when
deserializing. Thanks to Das Archive. 
o LOG4J2-104:  Convert LogManager binding to use "regular" java properties instead of XML
properties to workaround a
        bug in Oracle's xmlparserv2 jar. 
o LOG4J2-102:  The Facility value was being improperly calculated. Thanks to Emanuele Colombo.

o LOG4J2-101:  A NullPointerException would occur if no format value was passed to the SyslogAppender.
Thanks to Emanuele Colombo. 
o LOG4J2-99:  MapRewritePolicy had an extra call to putAll that caused updates to behave like
adds. Thanks to Das Archive. 
o Avoid NPE when duplicate LoggerContextFactorys are present. Allow factories to specify a
weight to allow
        real implementations to outrank test implementations. Provide a simple default LoggerContextFactory.

o LOG4J2-97:  Added several missing classes and methods for Log4j 1.x compatibility. 
o LOG4J2-94:  Interpolator was not stripping Lookup key separator when trying to locate the
default value for a variable. Thanks to Denis Treskunov. 
o Log4j 1.2 Category.forcedLog was wrapping the message with an ObjectMessage even if the
parameter was an

o LOG4J2-105:  Add ability to customize the names of the Levels in the LevelPatternConverter.

o LOG4J2-85:  Add ThreadContext.push(String format, Object... args) 
o Created combined jar to combine API and Core contents for users who only want the Log4j
o LOG4J2-87:  Build pdf of user's guide. 
o LOG4J2-29:  Added font and fontSize parameters to HTMLLayout. Replace newlines in message
with br tag. 

Apache Log4j 2.0-beta2 requires a minimum of Java 5 to build and run. Basic compatibility
Log4j 1.x is provided through the log4j12-api component, however it does not implement some
of the
very implementation specific classes and methods. The package names and Maven groupId have
been changed to
org.apache.logging.log4j to avoid any conflicts with log4j 1.x.
