Improvements

Graphics: GPU Instancing: Added support for Android with OpenGL ES 3.0 or newer. Note however that GPU instancing support is disabled for Android devices that have the Adreno GPU with only OpenGL ES 3.0, because of driver issues.

Graphics: GPU Instancing: Added support for Metal.

Graphics: Metal: Switched the shader backend to HLSLcc.

Graphics: Multi-scene occlusion culling now works correctly. Culling data has been extracted to a separate asset, and can be baked / reloaded with multi-scene setups. Note that the data is stored relative to the active scene, and is loaded correctly when loading any scene or group of scenes that reference it.

HoloLens: The tracking loss screen now renders at ~60 FPS (previously ~40 FPS).

Occlusion Culling: Unity now supports multi-scene occlusion culling. Scenes built concurrently will be computed as expected.

WebGL: Reduced the size of release builds by stripping away duplicate functions.

Fixes

Animation: Fixed a bug where deactivating a GameObject with an attached Animator could cause a crash. (822232)

Scripting: Fixed crash relating to construction of a generic Dictionary via reflection. (829757)
