IL2CPP: Updated code generation for il2cpp_codegen_get_marshal_directive_exception to safeguard against invalid C++ printable characters. (UUM-75811)
iOS: Fixed crash when rendering to backbuffer in Update. (UUM-77248)
iOS: Fixed determination of available shader texture binds count. (UUM-79712)
iOS: Fixed occasional deadlock in UnityWebRequest on abort. (UUM-77913)

Profiler: Fixed "Page range is outside of system region range. Please report a bug!" error for captured memory snapshots and opened in the Memory Profiler packaged, caused by Unity Objects getting created in-between of capturing the Managed Heap and Native Object data. Snapshots before this fix are not fixed by this change but future captures won't have the same issue. This also fixes cases where Unity Objects in a Memory Snapshot might have pointed at invalid data for their Managed Shell, which may have been most notable with MonoBehaviour and ScriptableObject types. This may also have fixed a vanishingly small amount of instances of reported "Leaked Managed Shell" objects where the Native Object part of the object got destroyed just after the managed Heap data was captured. The close timing makes the likelihood of all of these issues very rare and more likely the longer it takes to capture a snapshot. (UUM-77449)

Shadergraph: Fixed a bug where the Custom Function node's "Body" field would expand off-screen instead of scrolling. (UUM-76270)
Shadergraph: The name displayed in the Graph inspector when a BlockNode is selected has changed. (UUM-76081)
Shadergraph: Users can no longer select 'Delete' for context blocks. (UUM-76198)
SpeedTree: Camera facing leaves (cards) are facing incorrect direction. (UUM-70196)
SpeedTree: SpeedTree LOD Transition effect applying only to wind-enabled assets in SRP. (UUM-73540)
Universal RP: Fixed an issue where glClientWaitSync: Expected application to have kicked everything until job: 96089 (possibly by calling glFlush)" are thrown in the Android Player on some devices with PowerVR Rogue GE8320 GPU. (UUM-59572)
Universal RP: Fixed camera offset in the UI editor for the RenderObject RenderFeature. (UUM-76307)
Universal RP: Fixed shadow-map sampling artifacts present when using the Unlit DrawMode in the SceneView. (UUM-73236)

Version Control: Fixed a case of a hang happening on Editor quit. (VCS-1005810)
Version Control: Fixed a login failure for Enterprise installation. (VCS-1005903)
Version Control: Fixed history that was not shown when there was no desktop client installed. (VCS-1005756)

Version Control: Fixed the minimum supported version (2020.3.48f1 LTS) in the README.
Version Control: Fixed undo operation that didn't capture changes in packages. (VCS-1005617)

Version Control: Fixed wrong font size when changing to changesets view. (VCS-1004465)
VFX Graph: Read unexposed shader global properties when using a Shader Graph output. (UUM-78383)
Web: Fixed an issue that Application.persistentDataPath would not automatically persist, by adding a new JS config option "autoSyncPersistentDataPath: true" to enable automatic synchronization of Application.persistentDataPath over to IndexedDB. (UUM-60385)
WebGL: Fixed a bug where mouse button canceled events would emit after clicking and moving a mouse. (UUM-65367)
Windows: Fixed issue where Arm64 architecture DLLs are incorrectly copied instead of x64 when building for Windows x64. (UUM-76845)
XR: This might have been caused by initial PR of late latching. Reviewing the previous code it seems it should just be setting the local transform. (UUM-46969)
