So, Bugzilla 4.4rc2 is finally here! It took us more time than expected, but the performance bugs are all fixed and we also fixed two security bugs which are described in the security advisory. Bugzilla 4.2.5, 4.0.10 and 3.6.13 also contain these two security fixes, so you should definitely upgrade.
Compared to 4.4rc1, the new release candidate contains the last feature which we wanted for 4.4: the ability to add several criteria in a query against the same field. In Bugzilla 4.2,
"Flags changed to approval+" AND "Flags changed by email@example.com"
were disconnected, which means that these criteria would match all bugs which had the approval+ flag set and which had a flag changed by firstname.lastname@example.org. In Bugzilla 4.4, you can now force these two criteria to match the same field, i.e. that you only want bugs where the approval+ flag has been set by email@example.com. Thanks to Byron Jones (glob) for this great feature. :) Of course, this feature is not limited to flags, but works with all fields. See the release notes for more details. Also, 4.4rc2 should in most cases be much faster than 4.2 to run some complex queries. In my testing, some queries which took several minutes to complete now run in a few (tens of) seconds only. This is especially noticable with many columns displayed in the buglist. Another good reason to test it! ;)
The next release should be 4.4 final as I don’t think a 4.4rc3 is needed.
