Hi! I'm planning to do a preview release of those features this month, or, if worst comes to worst, in early February. I'm still aiming for this month - on the one hand, there's a ton of work, but on the other, I'm making good progress, so we'll have to see how it works out

By preview release, I mean that I'll post links to it on the forum and perhaps the blog, but the BMT Micro/preorder page download links wouldn't be updated. The point is to get some feedback and fix things up, and then put out an "official" 0.5a release a bit after that.
