Our favorite Flash tweening engine MC Tween is being updated to a more powerful and robust AS2 and AS3 extensions. Although it does not yet have all the nice extra features (like filter tween) like the old MC Tween, the new extensions do offer simplier and more structured syntax. So instead of using the old #include "mc_tween2.as" and

mc.tween("_x", 100, .3 , "easeInQuad");

we can start using aurina.transitions.Tweener, or just Tweener

Tweener.addTween(mc, {_x:10, time:.3, transition:"linear"});

We are big fan of MC Tween and are excited to see the next version. Meanwhile, examples, documentations and downloads are available here.
