Bullet 2.89 includes a new implementation of volumetric deformable objects and cloth based on the Finite Element Method, thanks to Xuchen Han. Two-way coupling between deformables and rigid/multi body is achieved using a unified constraint solver.

PyBullet is improved for robotics sim-to-real with realistic models of Laikago quadruped and an implementation of Deep Mimic.
