Update! WordPress MU 126.96.36.199 has a tiny fix for a post publish bug. You can download it from the usual place.
WordPress MU 188.8.131.52 has just been released and may be downloaded immediately.
This is a security and bugfix release and a recommended upgrade for every WordPress MU site. What happened to 2.8.5? I had it tagged and ready for release when Luke reported a little problem. It wasn’t possible to edit blogs! It was an easy bug to fix but code had been tagged and zip/tarball archives created so I had to create new ones. Thanks Luke! Saved the day. 🙂
Thanks to everyone else who contributed and helped in any way during the making of this release. Your help is invaluable.
This release also fixes a problem with slashes in blog and site options. You’ll be prompted to run the site upgrader. Please run it on all your blogs. For a more comprehensive look at what has changed recently, take a look at the Trac Timeline.
