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.

Q & A from the Apache Logging PMC
Q: Why did you do this?
A. The Log4j 1 code base has had some architectural flaws and the release process is complex, which is partly why few volunteers are maintaining this code base.
Q: What will happen to old Log4j 1 resources?
A: All resources will stay where they are. The documentation will be accessible and you will be able to download the framework as usual.
A: Yes, but we don't recommend it; we recommend using Log4j 2 instead.
Q: My friends/colleagues and I would like to see Log4j 1 being maintained again. What can we do?
A: If there are enough volunteers, there is nothing holding us back releasing Log4j 1 again. However, for the moment, we don't see this making sense, nor do we believe this will happen in near future.
Q: Why should I use Log4j 2?
A: We maintained Log4j 1 for 16 years, with some years seeing few releases. With version 2, we were able to build a full-featured successor. These reasons alone are worth considering Log4j over other logging frameworks.
