Beware CSRF when upgrading to 1.2!

This one caught me due to inattentiveness--if you're upgrading to 1.2, be sure to read the notes on CSRF. There's some changes that are really important if you're using forms. I think it's great that they're making it easier to keep your site secure, but beware, you might end up with 403 errors if you're not careful.
