Bugzilla 3.4rc1 is particularly exciting, because it's our first Release Candidate for 3.4. We did a really good job on this Release Candidate, I think--there's only one 3.4 blocker remaining (and it's only still there because we're waiting on an external party to do something). In other words, there are no known issues with the Release Candidate that are so bad that we couldn't just call it 3.4 next week if all goes well, and we've never actually been in that state for a Release Candidate, at least not as long as I've been around the Bugzilla Project.
One of the particularly exciting thing about a Release Candidate is that it has release notes! That means that all the new features are listed. There's a lot of really exciting stuff in 3.4, and you should take a look. There are some gems in the "Other Enhancements and Changes" section, too, so make sure you read that too. :-)
WebService Changes Since 3.3.4
Anybody who was writing WebService clients against 3.3.x development releases should know: we renamed the Bug.get_history method to Bug.history. You can still call it as Bug.get_history if you want, but that's undocumented and not recommended.
Also, we don't send <nil> for NULL items anymore--too many clients didn't support it. Now we just remove items from the returned result if they are undefined. (This is documented in the Bugzilla::WebService documentation.)
Progress Toward Bugzilla 3.6
There's been some activity on HEAD since our last update. We got a new WebService method to get attachment information, Bug.attachments. I've been working on making Quicksearch (the search box in the header and footer) even faster. Greg Hendricks (of Testopia fame) has been working on the ability for administrators to "disable" certain field values (so that they don't show up as options anymore, but remain set on existing bugs). And Bradley Baetz has been adding new hooks and working on improving performance in some important areas.
There's no ETA for Bugzilla 3.6, but if it works anything like how Bugzilla 3.4 works, we will have open development on it until two months after Bugzilla 3.4 is released, and then we will branch for 3.6 and the 3.6 branch will be "frozen" to only bug-fixes.
We have a Bugzilla Meeting next week, on Tuesday, July 14. Just read the page if you want more information! Anybody is welcome to attend.
