We made several changes today. Most of them are "Under the Hood" and you shouldn't see any difference since we tested the changes out pretty heavily on a devel box. Several odd little bugs have popped up tho, and we're squashing them as quickly as we can. Send your bug reports to firstname.lastname@example.org. The only noticable change you should see is some structural changes to the user settings pages: it was getting pretty unwieldly so we split it apart to make it easier to deal with.
