Is it still relevant to have this section in the documentation? News
Log4j 2 is now available for production. The API for Log4j 2 is not compatible with Log4j 1.x, however an adapter is available to allow applications to continue to use the Log4j 1.x API. Adapters are also available for Apache Commons Logging and SLF4J.
