<p>I'm currently developing an html/ajax air app and am about to invest some effort into making animations using jQuery. I could do this quite a bit easier using the css animations if air had that recent a version of WebKit. </p>

<p>I know some people have alpha/beta versions of air 1.5. If you do, can you let me know?</p>

I don't know offhand what AIR 1.5's CSS capabilities are, but it is a build with SquirrelFish, if that helps you track it down.
