Now caching microphone permission state instead of interacting with the Android system each time when checking it.

Added a field to the AnimationEvent inspector to control the reporting of errors when the event method cannot be found on the target object.

AssetDatabase.GetCachedIcon is now much faster when called for the first time on a Scriptable Object (and no longer deserializes the object in question).

The VideoClip importer is now running out of process when "parallel import" is turned On in the project settings.

Added the relevant URP replacement component button to the BIRP deprecation message help box.

Improved the RSUV sample to leverage the new shader reflection API.

Texture dependency tracking for the project's "HDR Cubemap Encoding", "Texture Compression Formats" and "Color Space" Player Settings is now done in a more fine-grained manner. This means that changing any of these settings typically results in a smaller number of textures being re-imported.

The SceneView camera extension for HDRP has been converted to UITK and it is now per Scene view.

Updated the existing required components structure to no longer be no-op.

Core configuration handling is improved.

Changed SubScene nodes in the Hierarchy window to be named after the SubScene and displayed with the Scene icon.

Added Intrinsics for Interlocked.Compare and Interlocked.CompareExchange.

\[InternalsVisibleTo\] attributes will no longer survive code trimming when targeting il2cpp

Installers on Windows can now take up to 60% less time due to an optimization in the compression strategy.

MaxSendRate is now bypassed when ArchetypeChunk structural changes (i.e. order changes) occur, so that ghost spawns and deletions are not delayed or rate-limited. Note that bandwidth consumption may increase marginally.

PhysicsComposer now implements the IDisposable interface where the public IDisposable.Dispose method simply calls PhysicsComposer.Destroy().

Replaces the legacy CustomSampler-based implementation of ProfilingSampler in com.unity.render-pipelines.core with the ProfilerMarker / ProfilerRecorder API.

Core configuration handling is improved.

Improved performance when merging Search Index artifacts of large projects with "Deep Indexing" enabled.

Improved UGUI Shaders sample to take advantage of promoted properties and subgraph improvements, by replacing former custom nodes with subgraphs.

Improved the way VolumeManager collects VolumeComponent types to avoid slow reflection overhead on Player startup.

Added OnFontMaterialRequest callback to complement the existing OnFontAssetRequest callback that allows custom loading of font related resources that are not contained in a Resources folder when using the <font> and <material> markup tag variants. Added new variant to the <font> markup tag to allow referencing a font asset by the source font's family and style name. Example: <font familyName="Roboto" styleName="Bold">. This new variant assumes the referenced font asset has already been loaded. Added missing OnColorGradientRequest callback to provide the same custom loading functionality that is available with the <font> and <material> markup tags. Added OnCharacterRequest callback to allow loading font asset resources based on the requested character.

Added a Find References in Scene option to the right-click context menu for visual elements in the Hierarchy window that have an authording-id.

Added an option in the UI Builder to export the UXML Attributes of elements in alphabetical order.

Moved the new recently added scripts to support entities in the new hierarchy from Packages/com.unity.entities/Unity.Entities.Editor/Hierarchy/Utility to Packages/com.unity.entities/Unity.Entities.Editor/Hierarchy.

Selecting a GameObject inside a subscene in the new Hierarchy will only show its GameObject authoring representation not its runtime ECS representation if there is an entity associated to it.

Updated SceneViewCameraWindow to use UIToolKit.

The GhostUpdateSystem's predicted ghost history backup lookup failure case now only attempts to rollback to the snapshot if said rollback isn't too severe. This change marginally worsens correctness in exceptional cases, but prevents egregiously large rollbacks.

Analytics events are sent to the correct table for custom display dialogs.

UPM logs now default to <ProjectPath>/Logs/upm.log, while still honoring explicit -upmLogFile overrides.

Changed the default behavior when deleting ScriptableObjects that were loaded from AssetBundles. OnDisable will now be called before deletion unless the setting is overridden. This can be done with an entry in the boot config or a command line parameter with "call-ondisable-when-unloaded-from-bundles" set to 0.

Updated the QNX platform logo.

Disabled profiling during Shader Graph code generation to fix errors that occurred in some circumstances.

Changed console log message for Compute shader variant GPU uploads to more accurately reflect its result.

Split compilation of D3D11 and D3D12 shaders so they may be compiled side-by-side for both renderers in a project regardless of whether or not D3D12 is compiled using DXC.
