> 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

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
> 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
