6000.5.6f1 Release Notes

Improvements

  • Unity Physics: ScheduleUpdateBroadphase previously overwrote the dynamic-tree update's JobHandle with the static-body change-check handle before scheduling the static-tree update, dropping the dynamic-tree job from the dependency chain, which can cause job safety errors when invoking Unity.Physics systems manually (for example; as is done by Netcode for Entities).

API Changes

  • Android: Added: Add support for SDK Platform 37

Fixes

  • Android: Negative values for Screen.brightness now restore the device's preferred screen brightness. (UUM-145925)

  • Android: Relaxed AGP 9's stricter R8 keep rule enforcement. (UUM-147136)

  • Animation: Added ellipsis to blend parameter name in blend tree node. (UUM-131825)

  • Asset Pipeline: Fixed the AssetDatabase re-importing assets endlessly when an asset depended on a default asset produced after an import crash. (UUM-146505)

  • Editor: Ensure SpriteRenderer material are indexed. (UUM-144279)

  • Editor: Fixed a memory leak caused by an undisposed CancellationTokenSource object in AsyncInstantiateOperation. (UUM-147016)

  • Editor: Fixed black bar artifacts in WinEditor that appear in certain combinations of Windows DPI scale and Unity UI scaling. (UUM-146885)

  • Editor: Fixed EditorWindows being opened by AssetImporter process and getting orphaned in the Taskbar. (UUM-145778)

  • Editor: Fixed instability in test by forcing texture import each test run. (UUM-122895)

  • Editor: Fixed issue where a local package failing to resolve can crash the Editor on MS Windows. (UUM-146678)

  • Editor: Fixed spacing issue in Framerate Scaler in the Adaptive Performance settings. (UUM-141453)

  • Editor: Project Auditor: fix invalid window layout message. (UUM-139591)

  • Entities: Fixed a MissingReferenceException in the Hierarchy window when a SubScene was destroyed during undo, scene unload, or domain reload. (UUM-147355)

  • Entities: Fixed an exception in the Hierarchy window when setting "Type of Worlds Shown" to include all world types. (UUM-146725)

  • GI: Fixed a crash that occurred when extracting shadow casters with null material. (UUM-132304)

  • GI: Fixed cone spot shadows missing with camera-relative culling. (UUM-147026)

  • GI: Fixed the Scenes in Baking Set list in the Lighting window so that a scene can be added again after undoing its addition, and so that removing a scene can be undone. (UUM-147477)

  • Graphics: Added IEquatable<T>, GetHashCode, and equality operators to Resolution and RefreshRate, avoiding GC allocations when comparing them or using them as Dictionary keys. (UUM-146197)

  • Graphics: Fixed rendering issues on XR when dynamic resolution is enabled with an injected RenderObjects pass. (UUM-142592)

  • Graphics: ScriptableRenderContext draws that use only SortingCriteria.OptimizeStateChanges no longer produce more SRP batches than SortingCriteria.RenderPriority for scenes that mix MeshRenderer and SkinnedMeshRenderer objects sharing a material. Previously the sort split these renderers into separate groups by renderer type, breaking SRP batches that the batcher would otherwise coalesce. (UUM-141053)

  • Netcode for Entities: A ghosted FixedList - that is cleared and later repopulated with the same data (e.g. during prediction rollback)

  • Networking: Bumps libcurl library to 8.20.

  • Package Manager: Package Manager related errors are thrown for Play Mode Scenarios additional editors when activated. (UUM-147009)

  • Physics: Fixed a crash with ArticulationBody component hierarchies due to the 64 link depth limit not being correctly enforced. (UUM-145530)

  • Physics: Fixed an issue with Rigidbody component serialization where prefab overrides (for drag/angular drag) saved in scenes on 2022LTS wouldn't be retained after upgrading. (UUM-147601)

  • Profiler: Memory Profiler under-reports ALLOC_TEMP_JOB_ASYNC footprint, causing unused blocks to appear as Untracked. (UUM-145712)

  • Scene/Game View: Fixed the SRP Volume gizmo not showing in the SceneView. (UUM-146740)

  • Shaders: Strip early subshaders if the RenderPipeline tag does not match any present renderpipeline assets for the build target. (UUM-141340)

  • UI Toolkit: Fixed an issue where some type converters would be ignored in the UI Builder binding window. (UUM-147357)

  • UI Toolkit: Fixed opacities not propagating in filtered elements. (UUM-147157)

  • UI Toolkit: Fixed PanelRenderer InvalidOperationException when the root is still parented if PanelSettings destroyed beforehand. (UUM-146244)

  • UI Toolkit: Fixed prefab override markers not showing in the Inspector and a stray horizontal scrollbar appearing after the Inspector scroll-area fix. (UUM-147367)

  • Universal Windows Platform: Fixed scroll actions re-triggering on mouse movement on UWP. (UUM-144660)

  • URP: Rendering Debugger - GPU Resident Drawer was resetting the debug data when entering and exiting playmode. (UUM-143210)

  • URP: When using Tile-Only mode in the renderer, setting Render Scale in the asset's Quality settings would display a warning only for values <0.95 or >1.05, but this has been fixed to display for all non-default values when Render Scale is not compatible with Tile-Only mode. (UUM-146401)

  • Video: Fixed AudioSampleProvider.sampleFramesAvailable callback never firing on macOS when using the VideoPlayer in API Only mode and disabling Unity Audio. (UUM-143660)
