WordPress 2.6 was officially released today. There are a ton of new additions, bug fixes and other coolnesses within this release so you might want to get a hold of the newest version and update your WordPress.
I already updated in case you were wondering.
EDIT | Apparently there have been some folks having issues with the upgrade. Chris Brogran, famed Twitterer and blogger, reported that his upgrade didn’t take and he had to roll back his installation. Sounds like the WordPress team needs to spend a little time looking into this, huh?
