> The Apache Log4j 2 team is pleased to announce the Log4j 2.4 release!
> 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 eighth GA release. It contains several bugfixes and new features.
> As of this release
> Log4j now requires a minimum of Java 7.

> Apache Log4j 2.4 requires a minimum of Java 7 to build and run. Log4j 2.4 and
> greater requires Java 7,
> version 2.3 required Java 6.
> 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.
> For complete information on Apache Log4j 2, including instructions on how to
> submit bug reports,
> patches, or suggestions for improvement, see the Apache Apache Log4j 2
