2021.3.42f1 Release Notes

Improvements

• Graphics: Add a IUnityXRTextureManagerInterface and a function pointer OnTextureDestroyed in it, which is called when VR RenderTexture is destroyed. On the plugin side, a callback assigned to this pointer is going to get triggered.

• XR: Update XR Interaction Toolkit package (com.unity.xr.interaction.toolkit) to v2.6.3

Changes

• Android: Updated bundletool up to 1.16.0 (UUM-70552)

• Burst: Improved error message for pointer-like types in non-readonly static fields

• Burst: Improved performance of Burst-compiled code in the Windows x64 Editor by only emitting context-saving code when the code being compiled contains a throw

• Package: Updated code coverage package to version 1.2.6

Fixes

• Android: Add UI for creating a custom settings.gradle template (UUM-27109)

• Graphics: The condition for the "Graphics.CopyTexture with a region will not copy readable texture data for compressed formats" warnings has been fixed to match the documentation so that when a CPU copy would not normally be attempted (ie., at least one texture is not readable), the warnings will not appear. (UUM-73721)
