OK, so I decided to try 2.0 after all. The upgrade went amazingly smoothly, and the plugins work fine, so I’ll add them to the Codex compatibility page.
Kudos to the WordPress team!
I can understand the RTFM/try it yourself attitude, but I’m not going to upgrade to 2.0 and then test the plugins, for the reason I gave originally. I’d already checked the compatibility list and found no entries for these two plugins, which is why I asked here. I’m not trying to make more work for anyone, I just thought someone might have already tried them and not yet updated the compatibility list.
I just found the 2.0 changelog in the codex; I’m not sure why I didn’t find it before.
