Remove deprecated BIRP support for PhysicsCore2D renderer.
Physics 2DBreaking
Release Notes Search
Search changes, fixes, and known issues across Unity releases.
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
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.
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.
URPChangeXR
Renamed the Light Falloff Mode option from Linear to Quadratic.
