Release Notes Search
Search changes, fixes, and known issues across Unity releases.
Architectural improvements to remove most main thread stalls ("Flush DSP connections" profiler marker) or inversely audio drop-outs, when adding / removing Audio Sources, effects and so on, especially under pressure.

Changed some error messages during Content Directory builds when an included Asset has error messages to make easier to find the culprit asset and understand the underlying error.
Improved Build Pipeline callbacks documentation to mention ContentDirectory and how to use the version number and BuildPipelineContext to enforce dependencies and rebuild of scenes properly.
Build PipelineImprovement
Updated the bundled 7-Zip to version 26.02.
Build SystemImprovement
Player builds no longer launch the Burst AOT compiler when no user assemblies reference Burst, speeding up build time significantly for projects that do not use Burst.
The Burst compiler server now starts asynchronously during editor initialization, reducing editor startup time.

Physics 2DImprovement
If the physics simulation produces a PhysicsBody transform with either NaN or Infinite values due to an unstable simulation then, if the body is writing to transforms, it is immediately disabled and its owner name (GameObject, Component or Transform) reported to the console with no transform writing done. This stops the Transform from containing invalid values and reports the identity of the object in question exactly when it occurs.
Physics 2DImprovement
Improved the Physics Outline Sprite Editor algorithm which now produces sprite contours that are more efficient for physics, avoiding collinearity and now uses vertex-spacing rules alongside minimal decomposition area and has sub-pixel accuracy. The overall improvement is a better default guess at the outlines and holes formed from a sprite.

PhysicsBody.SetBatchTransform() now has an additional "bool writePoses" flag to control if the Unity Transform are written to after the PhysicsBody poses are updated.
Physics 2DImprovement
PhysicsEvents of ContactBeginEvent, ContactEndEvent, TriggerBeginEvent and TriggerEndEvent can now be collated to produce a single Begin and End callback pair rather than multiple per-shape. This is critical to allow for "collider-style" callback behaviour where a logical group of shapes reports as a single compound shape.
Physics 2DImprovement
PhysicsJoint definitions now display as grouped, collapsible sections in the Inspector. Property drawers organize each definition into Anchors, Spring, Motor, Limit, Thresholds, Tuning and Drawing, so a definition reads as a handful of rows instead of a long flat list.
Physics 2DImprovement
PhysicsSpace now has several batch getter/setter methods to reduce round-trips from the engine including "SetBatchProxyAABB()", "GetBatchProxyAABB()", "GetBatchProxyCategories()", "GetBatchProxyUserHandle()" and "GetBatchProxyShapes".

PhysicsSpace now has the ability to specify a bound world with "PhysicsSpace.Create(PhysicsWorld)". With a world bound, PhysicsShape can be synchronized with "PhysicsSpace.SyncShapes()" overloads.
