All I can say to that is that Log4j 2.0 had 2 alpha releases, 9 beta releases 
and 2 release candidates over the course of 2 years before the GA release. 
Quite a few changes were made during that process that affected end users and 
none of our users complained. Every release indicated that is for use in 
testing and feedback. Had we not done that I am sure we would have gotten a lot 
less feedback.
