It’s ready. My blog seems to have survived the upgrade, and both of my plugins (Blogroll Autolinker and Valid Elements Fixer) seem to work fine. I think Blogroll Autolinker uses a function which is now deprecated, so at some point I’ll update it to use the new cooler 2.1 function.

I had to hack the LiveJournal Crossposter plugin because there’s not yet a 2.1-compatible version of it, so I’m about to find out whether it still works. Hint: find line 35 and replace it with this:

require_once(ABSPATH . '/wp-includes/link-template.php');
