Unity

What's new in this version:

Features:
- Android: Users can include custom asset packs into the build, by adding assets to the directory ending with '.androidpack'
- Android: When building Android App Bundle with Split App Binary enabled, Unity will create asset packs

Improved:
- Virtual Texturing: Tile requests are now returned via PopRequests more frequently
- Virtual Texturing: InvalidateRegion calls now generate new tile requests in their "importance" order. The importance is defined as a combination of the tile's screen space size and the the number of frames since the tile has been requested. This makes completing tile requests contribute more to the rendering result when InvalidateRegion is called continuously.
- XR: Updated OpenXR package to 1.2.3

API Changes:
- Android: Added: New APIs to manage fast-follow and on-demand delivered asset packs. The APIs wrap Google's PlayCore functionality.

Changed:
- Android: Gradle Plugin version upgraded from 3.6.0 to 4.0.1
- Android: Gradle version upgraded from 5.6.4 to 6.1.1
- Timeline: Updated Timeline package version to 1.5.6
- Virtual Texturing: Now PopRequests allows the destination list to have a different size than the texture stack's maxActiveRequests value

- Editor: Fixed an issue when running in Device Simulator, Touch.tapCount would no longer increased when taps happen in every frame
- Editor: Fixed an issue where Command+Backspace was not deleting elements from reorderable arrays
- Editor: Fixed an issue where the icon selector window did not close on selection undo
- Editor: Fixed an issue where there more than one click was necessary to interact with game objects in play mode when clicking between multiple game views

- HDRP: Fixed an issue where RenderGraph was missing support of motion vector.
- HDRP: Fixed an issue with velocity rejection when using physically-based DoF.
- Networking: Fixed an issue where the web request wasn't released incase of redirect to avoid memory leak.

- Physics: Fixed an issue where there wasn't a fallback behaviour to Rigidbody2D when inactive when converting local/world space point/vector
- Profiler: Fixed an issue in the System.Thread threads tracking and visualization in Timeline view of Profiler Window
- Scripting: Fixed a crash when closing the editor after a failed AssetBundle.LoadFromStreamAsync operation
- Scripting: Fixed an issue when including UIElements or Ui Builder packages, which could lead to errors when debug/release mode were changed.
- The error could also appear if changing a setting that would get the packages recompiled
- Shadergraph: Fixed an issue with GPU instancing support in Shadergraph
- UI Toolkit: Fixed a precision errors in gamma-linear conversions
- UI Toolkit: Fixed an issue where a panel remained unresponsive to user interactions even if it contains elements with huge dimensions
- URP: Fixed an issue where the SRP batcher was not working on OpenGL.
