We're excited to announce several new features in the GreenSock Animation Platform (GSAP) 1.12.0 that will increase not only "real" performance, but "perceived" performance as well. The innovative lagSmoothing() feature allows GSAP to automatically heal from CPU spikes that cause lag, all while maintaining perfect synchronization between all animations. And the new "lazy" rendering helps avoid layout thrashing when many animations start simultaneously.
TweenMax extends TweenLite, adding many useful (but non-essential) features like repeat(), repeatDelay(), yoyo(), staggered tweens, and more. It also includes many extra tools and plugins by default, making it extremely full-featured (TweenLite, TimelineLite, TimelineMax, CSSPlugin, AttrPlugin, RoundPropsPlugin, DirectionalRotationPlugin, BezierPlugin, and EasePack).
