• Mono: Added use of a relative path to the gdiplus dynamic library in the dllmap entry in the config file. (UUM-20719)

• Mono: Fixed an issue where the internal debugger would refuse connections after performing multiple switches between release and debug editor runtime optimizations. (UUM-16704)

• Particles: Fixed erroneous error message: "all(sheetIndexNormalized &gt;= 0.0f) &amp;&amp; all(sheetIndexNormalized &lt;= 1.0f)". (UUM-23304)

• Physics 2D: Fixed a bug where a Rigidbody2D without interpolation using MovePosition per-frame could result in a memory leak.

• Profiler: Fixed saving and loading of Profiler Data when the frame range contains frames that have been gathered from different different targets (e.g. from Playmode and from a built Player). Previously saved .data files with such data are irreparably corrupted and will crash on opening. This fix only applies to data saved from this version onwards. (UUM-14767)

• Scene/Game View: Fixed overlapped UI elements not being picked based on the order they are rendered. (UUM-18939)

• Serialization: Fixed issue where de-serializing Prefab containing a SerializeReference which has been refactored not handles MovedFrom. Improved AssetDatabase script type dependency so that if a missing SerializeReference instance type, re-appears importers depending on it will be trigerred. (UUM-6733)

• Shaders: Fixed a crash when loading shaders that are incompatible with the current hardware due to resource limits. (UUM-21964)

• Shaders: RenderingCommandBuffer.EnableKeyword(material, keyword) now properly affects rendering. (UUM-21676)

• UI: Fixed a crash could occur when the inspector window is rendering the header in IMGUI (case 1359247).

• UI Toolkit: Fixed dynamic-transform offset occurring at large coordinates. (UUM-20442)

• UI Toolkit: Fixed elements disappearing when changing both the border radius and padding at the same time. (UUM-4160)

• UI Toolkit: Fixed the UI Debugger text highlight when using the search field. (UUM-1887)

• Universal RP: Added functionality to stop clearing depth when using Overlay Camera. (UUM-4967)

• Universal RP: Disabled depth priming on GLES when MSAA is enabled. (UUM-2519)

• Universal RP: Disabled depth priming when baking reflection probes. (UUM-12397)

• Universal RP: Fixed ComplexLit mixed lighting by matching ComplexLit shader keywords with the Lit shader. (UUM-18553)

• WebGL: Fixed Unity integration test PowerPreferenceTests.cs failing to build. (UUM-15704)

• Windows: Fixed building to Windows using IL2CPP scripting backend when running on a Windows ARM64 machine.
