Well, the upgrade seems to have worked. Let's see if I can post this without anything blowing up.
If so, all the folks bitching about the lack of a search box on my blog will soon have one thing less to complain about. :-)
Update: It seems that TrackBack is somehow broken now. Grr. Must figure out what broke.
Update #2: Yes, there's now a search box on the right side of my main index. I need to hack on the template a bit to make it look right, but at least it works.
Alright, I've waited long enough. After reading the changelog, I've decided to make the jump from MT 2.21 to 2.63.
I hope this goes smoothly.
