tabsshow does not fire after upgrade to jQuery UI 1.10 (works just fine with 1.9)

Hello folks,
I am executing the upgrade of jQuery UI in my project, and I found a problem. I am trying to upgrade to jQuery UI 1.11, but after upgrading the jQuery-ui version the 'tabsshow' event is not firing up anymore. I checked the changelog, but I could not find anything related to this event. Has anybody here experienced this before?

I am currently using: jquery-ui-1.8.14 and jQuery v1.6.4.


The code the is not being executed after the upgrade is the following:
  1.  $(document).bind('tabsshow', function(event, ui) {
  2. ..
  3. code here
  4. ...
  5.         return true;
  6.     });
