I have just upgraded the blog to WordPress 2.0-beta 2.  I’m not quite sure if this is the full beta 2 release, or if it’s just a pre-release.  I grabbed it from svn this morning, and I will continue pulling nightly builds until the full WP 2.0 release.  It may end up being semi-nightly, but really this doesn’t affect you, my readers, at all.
