I'm always surprised how phenomenally hard it is to get people to test alphas and release candidates - it isn't until the actual major release hits the floor that a ton of input starts to roll in. Every release I think it'll be different but I have yet to be proven right.<p>That being said, 1.4.1 is effectively "it" for a while (at least a month or so). It's shipping in Visual Studio and Drupal 7 so it doesn't matter what bug fixes come in after this, a lot of people will be using this version of jQuery.
