WordPress 3.3 is getting even closer now that the fourth beta is here. As you'd expect at this point, it's just a bug-fixing release. That said, this only makes it more stable so if you've been weary of testing it, perhaps it's time.
"In Beta 4 we’ve fixed a bunch of bugs, cleaned up the UI, added real text in some of the screens that still had placeholder text in Beta 3 (post-update screen, the Dashboard welcome area, new feature pointers), and generally tightened things up," WordPress
explained.
The latest beta also comes with jQuery 1.7.1 and a lot of bugs related to that have been fixed.
WordPress 3.3 promises to be a solid release, there's a
new media uploader that's a lot more flexible but also easier to use. The dashboard UI has also gotten a few updates.
