Today we are releasing 4.4.1, 4.2.7, 4.0.11, and the unstable
development snapshot 4.5.1.
Initially, we released new tarballs and diffs for these releases
to the download site but found a new bug shortly after. New tarballs
and diffs have been uploaded to the site which we recommend everyone
update to if you downloaded the first version. To make sure you
have the fixed version, md5sum values are provided further down in
All of today's releases contain security fixes. We recommend
all Bugzilla administrators to read the Security Advisory linked below.
Bugzilla 4.4.1 is our latest stable release. It contains various
useful bug fixes, performance improvements and security fixes for
the 4.4 branch.
Bugzilla 4.2.7 and 4.0.11 are security updates for the 4.2
branch and the 4.0 branch, respectively.
Note that 4.5.1 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 4.5.1 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 4.4.1 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.
