"So I think I'm pretty safe to say that I plan to do the public release of v0.4 next weekend. Maybe Friday if everything goes very well. There are a few new features and snippets of content which I think will have to wait for a v4.1, but all the major stuff is in, so it should just be a few days to get it stable and polished enough for public consumption"
