Apache™ Logging Services™ Project Announces Log4j™ 1 End-Of-Life; Recommends Upgrade to Log4j 2

5 August 2015 --The Apache Logging Services™ Project Management Committee (PMC) has announced that the Log4j™ 1.x logging framework has reached its end of life (EOL) and is no longer officially supported.

Log4j saw its first release in 1999 and quickly became the most used logging framework ever. Over the years the project has released several versions of the initial Log4j codebase, and is now actively developing and maintaining version 2.

In the Log4j 1 lifecycle, there have been 21 Log4j 1 releases; the last one being in 2012. As of today, there will be no further releases of the Log4j 1 code base. Users are encouraged to upgrade to Log4j 2.

Apache Log4j 2 features a completely rewritten framework. In addition, it is faster, more reliable, and much easier to develop and maintain.

"All our volunteer efforts are now going into Log4j 2. Our community has grown again and we are actively maintaining Log4j 2," explained Christian Grobmeier, Vice President of Apache Logging Services. "We are so happy with the quality and stability of Log4j 2, we are convinced it is a fantastic replacement for Log4j 1."

Log4j 2 has had 19 releases thus far, the last 6 being marked as GA/General Availability, and the latest one being in May 2015.
