JQuery 1.9 has been released
For anyone making a shift from 1.7/1.8 to this, please don't overlook the jquery-migrate plugin (https://github.com/jquery/jquery-migrate/).You/we don't have to suffer the headaches of "what the heck changed since the version I was using...", the jQuery overlords have really done us a great service in offering this cool migration checker - so let's use it!
