WordPress put out an urgent security release today. If you are using an older version of WordPress you should consider upgrading to version 2.3.3 as soon as possible.
I was about to do the manual update when I was pointed to this tool from Scott's Twiiter. It's the WordPress Automatic Updater plug-in (GPL). WAUP is an easy point-n-click way to upgrade WordPress versions. It not only upgraded my copy of WordPress, but made backups first in case something went wrong. Very slick.
