Today we are releasing 4.4.5, 4.2.10, 4.0.14, and the unstable
development snapshot 4.5.5. All releases fix a security issue found
since the last release.
Bugzilla 4.4.5 is our latest stable release. Bugzilla 4.4.5,
4.2.10 and 4.0.14 are security updates for the 4.4, 4.2, and the
4.0 branches, respectively.
Note that 4.5.5 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 4.5.5 might not accurately
represent the behavior that 5.0 will have.
Note that when Bugzilla 5.0 is released (likely later this year),
the Bugzilla 4.0.x series will reach end of life. If you are using that
series, we encourage you to upgrade to 4.4.5 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.
