Apache log4j is a well known framework for logging application behavior. Log4j 2 is an upgrade to
Log4j that provides significant improvements over its predecessor, Log4j 1.x, and provides
many other modern features such as support for Markers, property substitution using Lookups, and asynchronous
Loggers. In addition, Log4j 2 will not lose events while reconfiguring.
This is the sixth GA release. It contains several bugfixes and new features.

Apache Log4j 2.3 requires a minimum of Java 6 to build and run. This will be the last release of Log4j 2 to
support Java 6. Future releases will require a minimum of Java 7.
Basic compatibility with Log4j 1.x is provided through the log4j-1.2-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.

patches, or suggestions for improvement, see the Apache Apache Log4j 2 website:
