Package Manager: Improved Project manifest files to repopulate with default dependencies when the files are empty or full of whitespace.
Universal RP: Added the
8192x8192option in Shadow textures.

Graphics: Optimize DOTS instanced properties loading code for URP and HDRP stock shaders.
HDRP: Avoid clamping to integers for HDR manipulation. (UUM-29767)
HDRP: Avoiding the conversion from string to type for each Custom PP.

HDRP: Improved water system performances.
HDRP: Optimize water surface scripting interactions.
HDRP: Reduced GC Alloc when using raytracing and HDRP. (UUM-40657)

EditorGraphicsSettings.TryGetRenderPipelineSettingsForPipelineto access settings of other pipelines than the currently active pipeline.
HandleUtility.GetOverlappingObjectsfor getting an ordered list of all pickable objects under the give mouse location.
HandleUtility.RegisterRenderPickingCallbackand a few peripheral structures that enables custom rendering-based picking solutions to be developed.
ObjectIdResult.DecodeIdFromColor. Users are now encouraged to use
HandleUtility.DecodeSelectionIdfor decoding and
HandleUtility.EncodeSelectionIdfor encoding selection IDs.
Editor: Obsoleted: Made PropertyCollectionAttribute obsolete. Use PropertAttribute constructor argument applyToCollection to make a collection attribute.
Graphics: Changed: BatchDrawCommand.visibleCount no longer has to be set to 1 when BatchDrawCommandFlags.HasSortingPosition is set
Graphics: Changed: HLSL
min16floatvariables are now translated to MSL
floatin all CPU visible buffers (e.g. Constant Buffers, Structured Buffers, Vertex Shader Input). When accessing these values inside shaders, they are casted to MSL
half(16-bit) for faster arithmetic operations. Any project that uses
halfin shaders and accesses this data as 16-float (from CPU) on iOS is incompatible with this change. For these cases, a new
#pragma metal_fxc_allow_float16_in_cpu_visible_bufferswas added so that HLSL
min16floatvariables are converted to MSL
halfin all CPU visible buffers (just like before).
