Release Notes Search
Search changes, fixes, and known issues across Unity releases.
Removed macOS x64 Editor and Player support.
EditorBreakingmacOS
Removed support for Mono-based Editor
EditorBreaking
The macOS character palette shortcut now only opens the palette while a text field is being edited.
EditorChangemacOS
Remove the obsolete HierarchyColor field in Subscene
EntitiesChange
Removed the Progressive CPU Lightmapper and the Lightmapper dropdown from the Lighting window; the lightmapper now follows the Default Light Baker setting in the Graphics settings, and scenes that used the Progressive CPU Lightmapper are automatically upgraded to the Progressive GPU Lightmapper.
GIBreaking
Surface Cache Global Illumination debug views are now displayed as a resizable Rendering Debugger overlay and no longer replace the scene's global illumination.
GIChange
Added an error banner in the main window if the project is using Built-in Render Pipeline
GraphicsChange
Changed AsyncGPUReadback to reject a readback whose destination NativeArray is still in use by a running job, and report the error through the callback instead of proceeding.
GraphicsChange
Deprecated the Baked Occlusion Culling authoring workflow in the Editor. New projects no longer expose its authoring UI, while existing projects retain the workflow and baked data and display a deprecation notice. Consider migrating to GPU Occlusion Culling where supported.
GraphicsBreaking
Disabled Built-in Render Pipeline rendering paths, render black instead.
GraphicsChange
Removed a warning displayed at build time in specific XR setup that is breaking build determinism for Content Directory builds.
HDRPChangeXR
Remove public keyword from topMostController variable as it is not part of public API
iOSChange
Removed support for x64 and Universal Simulator architectures.
iOSBreaking
Changed NativeList and UnsafeList to preserve only the first Length elements when capacity grows. Data written beyond Length through the raw pointer is no longer retained across a reallocation.
Removed the license type from the Unity Editor window title on Linux, so that it matches the window title on macOS and Windows.
LinuxWindowsmacOS
Removed UnityWebRequest.enableProfilerBodyCapture. The Web Requests Profiler module now captures request and response bodies whenever the Profiler is recording, so there is no longer a setting to turn on. Remove any assignment to this property; no replacement is needed.
NetworkingUUM-153039
NGO (com.unity.netcode.gameobjects) package was updated in the editor manifest to newest major version (3.0.0).
The content of com.unity.collections has been moved to an engine module, and the package is just a shim with typeforwarders, so it no longer has any dependencies. If you were relying on it having them, you'll need to depend on them yourself explicitly (most notably, com.unity.test-framework).
PerformanceTestRunInfo.json and PerformanceTestRunSettings.json are no longer generated during player builds that do not include test assemblies, as they are only read by performance tests running inside the player. Stale files left behind by an aborted test build are removed before such builds instead of being included in them.
Performance Test FrameworkBreaking
"ManifoldPoint.normalVelocity" is now only guaranteed to be measured when the shape is bouncy or hit events are enabled, and can read zero otherwise.
Remove deprecated BIRP support for PhysicsCore2D renderer.
Physics 2DBreaking
Setting "PhysicsWorld.maximumLinearSpeed" or "PhysicsWorldDefinition.maximumLinearSpeed" below "PhysicsConstants.MinMaximumLinearSpeed" now raises it to that minimum.
Loading a prefab or scene that stores prefab data in the format written by Unity 3.3 and earlier now logs a deprecation warning naming the asset. Save the asset to store it in the current format.
PrefabsChange
Removed the upgrade path for prefab data saved by Unity 3.3 or earlier, so prefab instances and per-object overrides in projects that old no longer survive being opened. Unity 6.7 warns when it loads an asset in that format.
PrefabsBreaking
Changed the Editor so that it emits C# compiler warnings for immutable packages, such as packages installed from a package registry. Warnings from these packages now appear in the Console window and the Editor log.
ScriptingChange
Changed text serialized files so they begin with a %UNITY format version directive, which makes an earlier version of Unity report an explicit error when opening a file saved in this version instead of loading it with missing data.
SerializationChange
Reflected function fallback keys now use the fully qualified signature (this will not impact correct usage of the ProviderKey hint).
ShadergraphChange
Surface shaders are now marked as deprecated.
ShadersBreaking
The URP sample template no longer includes a copy of the TextMesh Pro essential resources and uses the built-in resources from the uGUI package instead.
TextMeshProChange
Changed Constant Physical Size panels to account for the Game view's Low Resolution Aspect Ratios setting when resolving scale.
UI ToolkitChange
Changed theme style sheets to rank above Unity's built-in styles regardless of selector specificity; the previous behavior can be restored with the Legacy Theme Priority setting in Project Settings > UI Toolkit.
UI ToolkitChange
Importing localization shared table data that has two entries using the same key now renames the duplicate and logs a warning.
The Editor theme style sheet is now applied to the root of the Editor window panel instead of EditorWindow.rootVisualElement, so it no longer appears in rootVisualElement.styleSheets.
UI ToolkitChange
Changed how the batching runs for the completion of any remaining DebugDraw jobs still running from the previous frame in, before the streams are cleared for re-use. This may improve performance when using DebugDraw
Moved Light Falloff Mode from the URP Asset to Graphics Settings.
URPChange
Removed a warning displayed at build time in specific Light setup that is breaking build determinism for Content Directory builds.
URPChange
Removed a warning displayed at build time in specific XR setup that is breaking build determinism for Content Directory builds.

Renamed the Light Falloff Mode option from Linear to Quadratic.
