The first beta version of 1.7 was released yesterday, and today we’re releasing beta 2. We’ve fixed a couple more important bugs in beta 2 and it’s ready for testing.
The primary bug we fixed was the lack of updated .min versions of CSS and JS files. We simply forgot to update the compressed versions of our scripts and styles in beta 1, so anyone that wasn’t running with SCRIPT_DEBUG enabled, didn’t see any of the new CSS or JS, resulting in some broken features and display.
