So, I've moved the 2.1 branch into the trunk. I've also spent more than half my Saturday fixing and writing documentation.
Here's the 2.1 manual on the wiki! If you have some time, please read through it. It's a lot of work -- hopefully someone will appreciate it. :)
I also re-uploaded the 2.0.2 bugs-n-stuff that were on the Box2D wiki, here. A couple of other wiki entries got updated, too. Notice anything strange? Please do let me know.
There's a few changes upstream that I'll get around to including soon, but I'm a bit burnt out after the above. Nothing huge, though.
