Lots of great stuff in this release, like animations taking advantage of requestAnimationFrame.

You should do serious testing before upgrading though. Not just because this is alpha, but because .show() and .hide() work a lot differently now. They don’t do any fancy stuff to work with the CSS or return elements to the display type they were before hidden. These are hugely used methods. Chances are you have a few in your code base.

The best practice has become: don’t use those methods at all, only toggle classes which handle element visibility.
