-4. Improved performance of SAT for convex collisions.
-5. Fixed bug for sphere/capsule-convex deep penetration.
-6. Fixed bug where ``mjx.Data`` produced by ``mjx.put_data`` had different treedef than ``mjx.make_data``.
-7. Throw an error for margin/gap for convex mesh collisions, since they are not supported.
-8. Added ellipsoid plane collisions.
