Well, I have been following Apache 2 develpment for a while. This is a major milestone. I have been running it and it seems to be working nicely.
The Apache HTTP Server Project is proud to announce the release of version 2.2.0 of the Apache HTTP Server ("Apache").
This version of Apache is a major release and the start of a new stable branch. New features include Smart Filtering, Improved Caching, AJP Proxy, Proxy Load Balancing, Graceful Shutdown support, Large File Support, the Event MPM, and refactored Authentication/Authorization.

Remember that PHP is now at 5.1.1.
