(861347, 863060 ) - Particles: Fixed issue where sub-emitters were causing memory leaks

(862976) - Particles: Fixed issue where switching Render Mode could cause rendering artifacts

(868648) - Particles: Fixed rare crash when using the Trail Renderer and Multithreaded Rendering is enabled.

(862921) - Particles: Fixed rotation bug with mesh particles

(864208) - Particles: Fixed TrailModule crash when enabling trails and using ParticleSystem.SetParticles

(861409](https://issuetracker.unity3d.com/product/unity/issues/guid/861409/)) - Particles: Stretched billboards could apply scale twice if using Speed Scale

(859436) - Particles: Texture Animation could skip frames and display invalid data

(none ) - Physics 2D: Optimize the CapsuleCollider2D component intersection tests for speed and accuracy.
