I just upgraded to WordPress 2.0. It’s still using the same theme (for now) so nothing should look any different on the user end, but the administrator’s interface is radically different, and pretty nifty. I haven’t explored it enough to actually say what practicaly changes there have been, but it should be fun to mess around and see what it can do. If anyone finds any bugs or oddities caused by the upgrade, make sure to email me.
