WordPress 3.3 “Sonny” is out. I haven’t upgraded here just yet and might wait a few days to see how the plugin situation shakes out. There are some fantastic improvements in this release, including a drag-and-drop uploader and improvements for multi-user editing. Here’s the full changelog. I’ll let you know how my multisite installation here goes (I also run Somnambulonimbus on this instance).
Update 8:16pm EST: WordPress 3.3 is installed and running. Fast upgrade as always. If you’re using W3 Total Cache and hosting your wp-includes files on the CDN, you’ll probably run into trouble with the new toolbar (formerly known as the Admin Bar) if you’re caching aggressively. It took a few minutes for my new files to finish pushing to CloudFront, but after a couple refreshes, the proper CSS was in place and everything looked good.
Update 10:21pm EST: The WordPress download counter is always fun to watch after a new version is released. At the time of this update, it’s already been downloaded over 64,000 times. This includes in-place upgrades and .zip/.tar.gz downloads from the site, but not Subversion checkouts or one-click installs on web hosts.
