At long (long) last, the first community release of IronPython is now available – IronPython 2.7 Beta 2. The highlights of this release are the new zlib (which also enables gzip) and subprocess modules. There have also been a number of bug fixes.
Since Beta 1, we've moved all development to the Github IronLanguages project, although the issue tracker is still on CodePlex. This meant learning the build system, learning how to package a release (something that needs some work), and various other odds 'n ends. There are definitely some stumbling blocks that new people might trip over, so those should be taken care of as soon as possible.
The next release is scheduled for February 20th. The first IronPython Bug Weekend is scheduled for February 12-13th; more on that coming soon.
