### Improvements * MacOS: Support Visual Studio for Mac as an External Script Editor. Opens .sln (solution) file when double clicking a script. * Graphics: Added function to allow cube map textures to be compressed from script like their Texture2D counterparts. ### Fixes * ([884926](https://issuetracker.unity3d.com/product/unity/issues/guid/884926/)) - 2D: Added POT options in TextureImporter for Sprite. * (890858) - 2D: Fixed an error message "Dynamic batching: index buffer destination/source is NULL" when dragging a blank sub-sprite to scene. * ([889106](https://issuetracker.unity3d.com/product/unity/issues/guid/889106/)) - 2D: Fixed a misleading warning when using Sprite in 'Polygon Mode' for tiling in SpriteRenderer. * ([884970](https://issuetracker.unity3d.com/product/unity/issues/guid/884970/)) - 2D: Fixed Sprite data not copy when using EditorUtility.CopySerialized. * (none) - Analytics: RemoteSettings adding debug\_device flag in http header. * (none) - Android: Fixed manifest merging with new android sdk tools. * ([899553](https://issuetracker.unity3d.com/product/unity/issues/guid/899553/)) - Animation: Animator.Rebind should reset AnimatorController. * (896659) - Animation: Fixed crash in prepare frame due to deactivating Animator in script * ([901268](https://issuetracker.unity3d.com/product/unity/issues/guid/901268/)) - Animation: Fixed disabled Animator affecting scene objects. * (none) - Animation: Fixed a performance issue with GetLayerWeight. * ([900875](https://issuetracker.unity3d.com/product/unity/issues/guid/900875/)) - Animation: Fixed StateMachineBehaviour callback on interrupted transition. * ([899198](https://issuetracker.unity3d.com/product/unity/issues/guid/899198/)) - API Updater: Fixed a crash in ScriptUpdater.exe when user scripts contains methods taking pointers as parameters. * (none) - Editor: Fixed a bug which broke holding alt to pin center of PrimitiveBoundsHandle (affects edit modes for BoxCollider, CapsuleCollider, BoxCollider2D, CapsuleCollider2D, etc.). * (899285) - Graphics: Fixed a regression where a Deferred Camera was throwing a "Dimensions of color surface does not match dimensions of depth surface" error message when a RenderTexture was used. * (900527) - Graphics: Fixed a regression where image effects weren't working as expected in the Scene View. * (899365) - Graphics: Fixed a regression where the objects shaders become unlit when a RenderTexture with Anti-aliasing is active and the Camera RenderingPath is set to Deferred. * (903086) - Graphics: Fixed the Dynamic Batching rendering code in order to be able to handle valid meshes that have no submeshes. * (890527) - Graphics: Improved the mechanism for handling imposters.
