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.

Bugzilla is a “Defect Tracking System” or “Bug-Tracking System.” Defect Tracking Systems allow individuals or groups of developers to keep track of outstanding bugs in their product effectively. Most commercial defect-tracking software vendors charge enormous licensing fees. Despite being “free”, Bugzilla has many features its expensive counterparts lack. Consequently, Bugzilla has quickly become a favorite of thousands of organizations across the globe, and is widely regarded as one of the top defect-tracking systems available.
