It’s up on the iTunes store for iOS, and the release has been tagged in our source tree. We’re delayed on the mac and windows releases because, respectively, there’s a bug in SDL that breaks our fullscreen support in 10.7 (which we think we’ll probably have a solution for in a few days), and as for windows, I don’t even know what we’re gonna do, because across our entire team, I’m not sure we have a single guy who can compile for windows at the moment.
We’re quite open to outside help on that. If you’re good at compiling software for windows, we’d love your help (if you can do a really good job, and solve our ongoing compatibility problems, there might be a business opportunity there).
