Maybe it's the first flush of springtime that's reinvigorated activity, but I do see significantly more activity in the last week or two. That's great. Especially since a lot of the activity is going into older issues too. The number of open issues is declining; it was over 70 a month or two ago and is now down to just over 50. That's a good trend.
Our 0.4 release was Oct 31 2010. Given a general pattern of releasing every 6 months, that would suggest end of April for 0.5. I see no reason to rush, but reason to start asking those release questions: - What do we want out of 0.5 as a release? I suggest it be viewed as nearly a release candidate for 1.0; the APIs and functionality should be substantially set by 0.5, to be polished for a 1.0 release in Q4. - What is marked for 0.5 that just isn't realistically going to be done by anyone in a few weeks? - What isn't in JIRA for 0.5 that would be nice for 0.5? In particular, there are 24 issues still marked as targeted for 0.5. Here's an open invitation to punt issues to unscheduled, and for fixing/resolving issues. I think 0.5 will also be a good milestone to ask if anyone wants to become an emeritus committer.
