I have at least one confirmed Google Web Optimizer plugin failure with 3.3. It may or may not be related to how it was updated (client's site.) The author's site is in Italian from what I can see. :-)
Does anyone know what happened to loop.php? Looks like it's no longer used or needed in the twenty_twelve theme.
