I think I forgot to mention this except on the French list; earlier today I added a rollback-last-edit function (for sysops). It's currently accessible from the user contributions page; next to 'top' revisions, there's a 'rollback' link which will resave that page with the most recent revision by an author other than the most current.
It's basically just a shortcut for page->history->old revision-> edit->save, not a new functionality, but rather handy if you've got to do more than a couple at a time.
(See changes to Article.php; slighter to Language.php, wiki.phtml, SpecialContributions.php)
I've also put the current CVS revision of everything as of a few hours ago onto all the languages, so we should be running consistent.
