• The bug in wordpress 2.1 which caused tags to vanish when a comment was made has been fixed Turns out that if you add a comment, it’s fine; but if you approve one, the tags will still vanish. Hrmpf.
• I’m pretty sure you won’t end up with double-tags in feeds, any more
• I’ve rejigged the way tags are added to feeds
• Tag intersections should be working properly again
• Tags can be added to pages (and will be included in tag cloud counts… displaying on tag pages, though…)
• No more XSS vulnerability with the ajax URL parameter
• There’s an invisible technorati tags format, now! (Handy for using with the automagically include tags on the Options > Tags page)
• Search includes tags [I worry about this bit! let me know if you see anything weird]

I’ve tried it using wordpress versions 2.0.4, 2.0.7 and a 2.1 beta; and it seems to work in all three (:

Attention WordPress 2.1 beta users!

Here’s a temporary patch for resetting tags.
Modify ‘ultimate_save_tags()’ function on ‘ultimate-tag-warrior-actions.php’ about line 502:
if (isset($_POST['comment_post_ID'])) return $postID;
if (isset($_POST['not_spam'])) return $postID; // akismet fix
if (isset($_POST["comment"])) return $postID; // moderation.php fix

This seems to work.

(If you go to Manage > Tags, and click the Tidy Tags button; the postmeta guff will be cleared out)
