I have finally got around to delve into SCM. My choice of version control system is Mercurial, which is both free and a bliss to use. (Joel Spolsky's tutorial was tremendous help too.) This joy is all I have in the way of a reason to make this post.

However, since I'm already here: XRhodes now has the XR::Predictor class which you can use to, well, predict values (such as future position of an entity based on its movement etc).

Also, I know, I've never released v0.81 for OS X, but v0.82 is just around the corner.
