I updated this site to WordPress 3.2, a new major release. I’m still kicking the tires, but so far, I like what I see. The Admin interface has been redesigned, and there’s a new default theme, TwentyEleven, which I’m using (actually, I made a child theme so I can inject some CSS tweaks to make my Like/Tweet buttons behave).
I had to update my MySQL database on my web host (mediatemple) to MySQL 5, which I hope didn’t break anything on the other sites I host. Let me know if you notice any weirdness, or have any other problems.
