Crash on il2cpp::vm::LivenessState::AddProcessObject when using Social.LoadUsers and then changing scenes (1270230)
iOSKnown issueBlocker
Temporarily removed the Burst compiler warning about exception throws not in \[Conditional("ENABLE\_UNITY\_COLLECTIONS\_CHECKS")\] methods, to let us address user feedback. The next minor version of Burst will reincorporate this in a more friendly manner.
Package ManagerBreaking
Added: Added writeable WheelCollider.sprungMass, to enable explicit mass distributions. In addition to that, expose WheelCollider.ResetSprungMasses() to reset the vehicle back to automatically calculated implicit sprung masses. It's the same usage pattern as with Rigidbody.inertiaTensor / Rigidbody.ResetInertiaTensor().

Enabled Unity perform Android SDK update with elevated privileges on Windows. Previously if Android SDK/NDK would be installed in folder like Program Files, Unity wouldn't be able to update Android SDK. With new behavior user will be prompted with a dialog where Unity will ask - if it can run sdkmanager.bat with elevated privileges. (1281951)
AndroidFixWindows
Fixed Switch internal Unity allocator to DynamicHeapAllocator which is compatible with Scudo allocator introduced in Android 11.

Fixed issue where thread statics that reused thread static slots would not adhere to type alignment. This would cause the garbage collector to incorrectly clean up thread static data because it would only scan pointer aligned memory for references. This would lead to memory becoming corrupted and inducing random crashes. (1266322)
ScriptingFix
Canvas RectTransform size calculation now done for standalone renders as well. Camera needs to be enabled to pick up the RenderTexture size change. (833456)
UIFix
