The core team was up late last night specifically to push out Release Candidate 1 of WordPress 3.3. The milestone comes a bit later than was intended by the 3.3 Project Schedule, but it still puts the project in a position to release the final version by the end of 2011.
Normally I’d say you can read more about the RC1 status on WordPress.org, but as you might expect a late evening release tends to lead to shorter release posts. Still: we’re talking piping hot WordPress here, and it’s ready for another round of testing, if you’re willing.
Assuming you’ve been playing with 3.3 a bit already, share a thought or two in the comments.
