Version 0.6 is done, which adds compatibility with WordPress 2.3’s native tagging. It also adds search results to 404 pages, as well as a list of recent posts. There’s also a bug fix, so that the Table of Contents template only returns direct children, not grandchildren. (I might be the only person with enough levels of subpages for that to be an issue).

I’ve dropped support for Ultimate Tagging Warrior and older versions of WordPress completely.  I don’t think that will affect anyone, but if you’re not running 2.3, don’t bother upgrading.
