we're currently collecting everything that has changed between jQuery UI 1.5.3 and jQuery UI 1.7. We will later
use this information to write a comprehensive upgrade guide for all users that will be featured in the jQuery wiki
and in our website.
You can find the current collection here: <a href="http://wiki.jqueryui.com/Upgrade-Guide">http://wiki.jqueryui.com/Upgrade-Guide</a>
I've pretty much updated everything I could with the exception of tabs. Please feel free to add anything you
think would be valuable to note, and of course, information on how the tabs plugin changed.
