WordPress 3.4 uses the jQuery UI library ver: 1.8.20. The latest stable release available from jQuery UI website is 1.8.21. (as at 2012-06-17).
Unfortunately the latest version on Googles’ CDN, at this point, is 1.8.18.
One option is to modify the code by duplicating the hack for the scriptaculous version. (around line 238) as in:
if ( 'jquery-ui-' == substr($name, 0, 10) && '1.8.20' == $ver ) {
$ver = '1.8.18';
}
Cheers,
Mark
