I know I can't get a release date, I'm not asking for one.

Having spent some time looking through 4.0.x bugs, it seems there has been some (critical) bugs fixed, so I was curious as to the timeframe for the next maintenance release. Are we looking at any day now, 1-2 week, a month, Real Soon Now, etc?

I doubt that the devteam will commit themselves unnecessarily, and other than that your guess is as good as ours: which is that updates typically arrive every month or two, or sometimes three. Last update (as I write this) was v4.0.2 on 18th Jan, so we haven't even quite reached the lowest end of that range yet.

4.0.4 was released today actually. Files are being uploaded now.

Yeah I saw that. In fact the release announcement went up while I was opening Bug #8357.
