In the Bugzilla 3.4 area, we just made some more changes to how the login form in the header and footer work. Now it's easy again for users to discover how to reset their password--when we moved the login forms into the header/footer, we at first didn't have any way for people to discover how to reset their password, but now there's a link and everything works really nicely. You can see how it all works on the Bugzilla 3.4 Test Installation.
We're getting somewhat closer to Bugzilla 3.4rc1. We found a few more blockers, so those have to be resolved, and there's also release notes that need to be written before we can have a Release Candidate.
One new feature of Bugzilla 3.4 that we haven't talked much about is the "See Also" field. This is a field where you can put a URL to a bug in another Bugzilla installation or to a Launchpad bug. The "See Also" feature isn't quite complete--in the future, we also want to make it update the other installation so that the other installation knows that you're referring to it. We also want to fix up the display, and get summary/status/resolution information on the remote bug, etc. But for now it does check that you've entered a valid bug URL, and at least you can somehow record that bugs in different Bugzilla installations are related to each other, and there's a WebService interface for updating the field.
For installations that don't need the "See Also" field, you can turn it off by disabling the "use_see_also" Parameter.
Bugzilla 3.6 (HEAD)
We're working on various interesting things for Bugzilla 3.6, though our focus recently has been on 3.4rc1, so there are a lot of patches awaiting review for HEAD that haven't had the time to be reviewed. People are working on the ability to disable field values and some cool WebService enhancements, but of course our main focus is fixing up the HCI issues that the Carnegie-Mellon research team discovered in their 2008 study.
