Currently we do not support GreenSock Tweenmax.
You are still able to manually add it and use it but we're unable to ensure it will render on all devices correctly as expected. We're working on restoring this compatibility.
We've built in support for the jQuery Transit animation library along with tutorials here. You can also use CSS based animations.
If you need help converting your animations or have a related issue please email us at: firstname.lastname@example.org.
