I just upgraded to WordPress 2.7 [1]. Everything seems to work as usual now. I did have to update the WP-Email, WP-Print and WP-Sticky plugins, and regenerate the permalinks.
Now, of course, the entire administration side of WordPress looks different, and I have to get used to it, but in general I have to say it looks nice. If you notice any errors on this blog, please let me know.
