yeah, similar for Android: any time you have a worthwhile bug fix, an actual release is helpful to us in terms of process. a small update doesn't cost us much anyway, and "earlier is always better than later" --- no matter what time of year it is, the sooner you have a release, the sooner we take it, and the sooner the bots and meatbag can start banging on it, and the more confidence we can have when it actually ships :-)
(that said, we haven't had trouble with 10.38, but -- especially when we're this far from the next release -- i'm not going to quibble about "important" versus "unimportant" upgrades! even in those kinds of circumstances, "release early and often" is still a help, because it reduces the likelihood that we'll need to backport anything -- because it's already in the oldest branch we need it in -- or the number of places we need to backport too -- because it's at least in _some_ of the older branches.)
