Release of Bugzilla 4.5.2 and 4.4.2

Today we are releasing 4.4.2 and the unstable development snapshot 4.5.2.

Bugzilla 4.4.2 is our latest stable release. It contains various useful bug fixes for the 4.4 branch.

Note that 4.5.2 is an unstable development release and should not be used in production environments. We are not yet feature-frozen at this time so the features you see in 4.5.2 might not accurately represent the behavior that 5.0 will have.

Note that when Bugzilla 5.0 is released, the Bugzilla 4.0.x series will reach end of life. If you are using that series, we encourage you to upgrade to 4.4.2 now.
