Preview of Final 2019.2.0a4 Release Notes
System Requirements Changes

Scripting: Make the GarbageCollector.GCMode property only throw an exception on unsupported platforms when trying to change it's value, not when reading it.
- Android: Bundletool is updated up to version 0.7.2.
Android: Mimic TouchScreenKeyboard.hideInput by drawing input field outside the screen, when this property is true.
Asset Import: Compressor Quality can now be set in the texture asset import settings for BC6H and BC7 formats allowing compression quality to be traded for import speed.
Editor: Added a message box whenever the OS fails to delete an asset when deleted from the Project Browser view.

Terrain: Added new callback APIs to monitor the terrain texture changes:
- TerrainAPI.TerrainCallbacks.textureChanged These callbacks tell both the rect region being changed and if the change is CPU synchronized or not (i.e. GPU only).
Terrain: Added new TerrainData APIs for easier modifying the terrain textures:
TerrainData.CopyActiveRenderTextureToTexture These two may be used for copying the content of the active RT into the terrain textures, optionally delaying the CPU synchronization, for instance at the event of mouse move in the middle of painting.
TerrainData.DirtyTextureRegion These two may be used alternatively to the two functions above if the user directly changes the GPU resources by other means.
- TerrainData.SyncTexture These two may be used to do a full synchronization from GPU to CPU, for instance at the event of mouse up.
Terrain: Deprecate Terrain.ApplyDelayedHeightmapModification. Use TerrainData.SyncHeightmap instead.
Terrain: Deprecate TerrainData.UpdateDirtyRegion. Use TerrainData.DirtyHeightmapRegion instead.
