Built by Maven

2.0.1 (2014-07-29)

This is the first patch release of Log4j 2.0 which contains numerous bug fixes.

Apache Log4j 2.0.1 requires a minimum of Java 6 to build and run. 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 Log4j 2 website.
