No problems here upgrading Movable Type from 2.51 to 2.62. At least, so far. I removed some CDATA declarations and added the encode_xml="1" attribute to some tags in my RSS feeds, but other than that, all is well.

A+++ #1 MT2.6 feature I haven't seen mentioned yet: meaningful page titles on the editing site.

I took the opportunity to also fix my comments RSS feed, which I hadn't converted over to Adam Kalsey's SimpleComments plugin yet. After making the change was when I remembered why: SimpleComments has to be in an entry context to do its thing; if you just plunk it in one of your index templates, it'll error out, preventing the build.

Changing my feed back would be a bummer, so instead I fixed it. Gotta love open source.

I also fixed my RandomOTDEntry plugin, even though I don't think it's my bug. Looks like I'm going to hack on Radio for a bit, but hopefully later tonight I can do the entry categorizer plugin I want (the one that Kevin Shay's FilterCategories isn't). It's for the quick links box at the top of my main index page; I made a "Threads" category to use like the "Threads" sidebar I had in my Radio weblog, but I can't exclude them from the main list without such a plugin. Tsk.

One feature I would like would be less automatic TrackBack: I always find I'm accidentally sending pings somewhere I'd rather not, but I still don't want to look up, copy, and paste the TB URL manually. I'd like MT to automatically fetch the TrackBack URLs, but then prompt if it should ping them. Kinda complicated UI, but that's what I'd like.

I'm also working on a BeipMU plugin, but you probably don't care about that.
