The Apache Log4j 2 team is pleased to announce the Log4j 2.3 release! Apache log4j is a well known framework for logging application behavior.

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.
