What's new in this version:

Fixes:
- 2D: Fixed crash on when passing array of nulls to SpriteAtlas.Add
- Animation: Fixed a crash when parenting an GameObject during an AnimationEvent
- Asset Pipeline: Optional parameter added to SceneManager.UnloadScene function allowing to unload assets embedded in a scene without calling UnloadUnusedAssets

- Editor: Fixed an issue where text flickers when displaying a button or label using the IMGUI that has a long text with wordwrap enabled
- Editor: Fixed crash and validation errors when opening editor windows
- Graphics: Disabled GPU skinning in the Editor when Graphics Emulation is enabled
- Graphics: Fixed an issue where Light Probe Proxy Volumes did not function correctly with Vulkan as the graphics API
- Graphics: Improved terrain painting that produces quantization when using OpenGL API
- Graphics: Vulkan: Various stability, performance and correctness fixes
- Graphics: Vulkan: Various stability, performance and correctness fixes
- Graphics: [ShaderGraph] Fixed Transparent preview not clearing framebuffer
- IL2CPP: Add support for marshaling fields which are arrays of structs which in turn have arrays as fields
- IL2CPP: Added protocol support for IPv6 on Windows
- IL2CPP: Correctly indicate that IPv6 is not supported on non-IPv6 platforms
- IL2CPP: Emit proper C++ code when type names include characters that are not valid for C++ source code
- IL2CPP: Fixed a crash when using the Environment.MachineName property on some machines when targeting UWP and make it return results consistent with the Standalone Player
- IL2CPP: Fixed an intermittent crash in the native linker on Android
- IL2CPP: Fixed InvalidCastException that can sometimes happen when passing managed object that derives from a native Windows Runtime class to native code. For instance, this happens when deriving from Windows.UI.Xaml.Control.ContentDialog and trying to show it
- IL2CPP: Generate proper C++ code for an out parameter used as SizeParamIndex
- IL2CPP: Handle null explicitly casted to an array and indexed
- IL2CPP: Loaded field addresses via unsigned native integer types properly
- IL2CPP: Prevent a compilation error in generated C++ code when the ldtoken opcode is used in some cases
- IL2CPP: Prevent an compilation error in generated C++ code when an enum field is marshaled
- IL2CPP: Prevent an exception during IL2CPP code conversion that can happen with Trace statements in some cases
- IL2CPP: Prevented a crash at runtime with the .NET 4.x equivalent scripting runtime that can occcur when an enum is nested in a generic type
- IL2CPP: Properly generate code using the in modifier for parameters on abstract methods in a generic type
- Package Manager: Fixed moving files in the editor project view (drag and drop) not working in local packages
- Particles: Fixed erroneous Particle System error message: "Sub-emitters must be children of the system that spawns them"
- Particles: Fixed Frame Debugger failing to show draw call information for Particle Systems
- Particles: Fixed incorrect curve evaluation when using the Limit Velocity over Lifetime module with a micture of optimized and non-optimzied curves
- Particles: Fixed particle bounds when using Sprites in the Texture Sheet Animation Module
- Particles: Fixed particle trails could being culled incorrectly when using the World Space trails option
- Particles: Fixed regression bug where offscreen Particle Systems failed to play
- Particles: Fixed scaling regression bugs with Particle Systems
- Particles: Fixed Velocity Module Speed Modfiier not applied to the initial simulation step of newly spawned particles
- Particles: Update particle bounce light immediately when the multiplier is changed on the Light
- Physics: Ensure that ContactPoint2D and Collision2D types do not get stripped causing a crash
- Prefabs: Fixed references to Prefabs from scene getting lost if prefab is modified
- Prefabs: Updated Undo to return Prefab instances with missing assets to previous state correctly
- Scripting Upgrade: Fixed crash in ScriptUpdater.exe when code contains qualified references to methods of type that were statically imported (#using static)
- Shaders: Fixed incorrect shader code generation with tessellation shaders when using the Vulkan API
- Universal Windows Platform: Fixed IL2CPP crashing when using certain new types (like Windows.Foundation.GuidHelper.Equals) in Windows SDK 17763 or newer
- Universal Windows Platform: Fixed memory leaks on .NET backend when calling Mesh.SetVertices(), Mesh.SetUVs(), Mesh.SetTriangles() methods
- Windows: Fixed setting refresh rate in exclusive fullscreen mode having no effect on D3D11 and D3D12
- XR: XR devices in new input system package are now all Y-up is away from the user
