Today we are releasing 4.2.4, 4.0.9, 3.6.12, and the release
All of today's releases contain security fixes. We recommend
all Bugzilla administrators to read the Security Advisory linked below.
Bugzilla 4.2.4 is our latest stable release. It contains various
useful bug fixes and security fixes for the 4.2 branch.
Bugzilla 4.0.9 and 3.6.12 are security updates for the 4.0
branch and the 3.6 branch, respectively. 4.0.9 contains several
useful bug fixes and 3.6.12 contains one as well.
Bugzilla 4.4rc1 is our first Release Candidate for Bugzilla 4.4.
This release has received QA testing, and should be considerably
more stable than the development releases before it. It is still not
considered fully stable, and so you should understand that if you use
it, you use it at your own risk
If feedback from this release candidate indicates that it is mostly
stable, then Bugzilla 4.4 will be released in a few weeks. If feedback
indicates that more extensive fixes are needed, there may be another
release candidate after this one.
Note that when Bugzilla 4.4 is released, the Bugzilla 3.6.x series
will reach end of life. If you are using that series, we encourage
you to upgrade to 4.2.4 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.
