We encourage all Bugzilla administrators to test out 3.0rc1 and report any bugs that you find! Note that Release Candidates are more stable than development releases, having had full QA testing. However, they are not fully stable releases, since they haven’t had as much real-world testing as stable releases. Depending on your feedback on this release, we should release Bugzilla 3.0 by early April.
