Animation.looped has been renamed to Animation.loop. It's a boolean you can toggle at run-time to turn on/off animation looping.
A single Animation object now has 3 new events: onStart, onLoop and onComplete.
Animation.loopCount holds the number of times the animation has looped since it last started.
Animation.stop has a new parameter: dispatchComplete. If true it'll dispatch an Animation.onComplete event.
