The goals for 0.0.3 are listed in the coarse
roadmap I wrote a couple of days ago. Most of the features are already there, but I still want to add more content to better demonstrate them. There are also some bugs to fix and some cleanups to do so it looks like 0.0.3 won't happen until February.
Releases after this should occur more frequently since the serious infrastructure and content creation related issues are resolved by 0.0.3. It won't be a very impressive release in and of itself, but the internal changes will make future development much easier. 0.0.4-0.0.9 will all be easy content creation and gameplay scripting releases since the major engine features required by them are there already.
