Retrieved 2026-11-10Unity Transport: Fixed an issue where sending packets on UDP connections that don't have a remote peer anymore could eventually result in exhausting the receive queue, causing the server to not be able to receive anything anymore.
Unity Transport: Fixed an issue with the NetcodeInterop layer which would cause connection failures when using NGO transports that use a single buffer for all receive operations (for example the community Facepunch transport does this).
Unity Transport: Network interfaces are now automatically disposed of before domain reloads. Without this protection, socket handles could be leaked which would cause errors when trying to re-bind to the same port later on. Note that this isn't a replacement for properly disposing of NetworkDriver objects; it's only a protection in cases where that's not done.

Fixed a regression in the handling of partial sends. In rare cases, the same dynamic ghost chunk hits the partial boundary at roughly the same entity index every tick. This indefinitely causes a subset of its ghosts to no longer be added to the snapshot.
Fixed a spurious "JobTempAlloc has allocations that are more than the maximum lifespan of 4 frames old" warning that appeared when baking a ghost prefab set to Owner Predicted mode without a GhostOwner component.

UUM-115186: Colliders with IgnoreCollision take significantly longer to be destroyed
How to reproduce: 1. Open the “IN-111471.zip“ project 2. Open the “SampleScene” 3. Enter Play Mode 4. Select the “PhysicsColliderCleanupTester“ GameObject 5. Enable and disable the “PhysicsColliderTester“ Component a few times to stabilize the performance 6. Observe the times logged in the Console 7. Enable/Disable the “Use Physics Ignore Collision“ checkbox 8. Enable and Disable the “PhysicsC…

UUM-148731: "InvalidOperationException" and "System.Exception" errors are spammed in the Console when changing Entity Simulation Singleton Type to "No Physics" in Inspector during Play Mode
Steps to reproduce: 1. Create new Unity project using Universal 3D Template 2. Open Package Manager 3. Find and install Character Controller package 4. Once installed, enter Play Mode 5. In Hierarchy window expand Default World GameObject 6. Select “Entity(21634:7)” GameObject 7. In Inspector window > Simulation Singleton > change Type from Unity Physics to No Physics 8.

Physics 2DFix
"PhysicsWorld.drawTarget", "PhysicsBody.drawTarget", "PhysicsShape.drawTarget" and "PhysicsJoint.drawTarget" now log a warning and keep their current value when assigned a value that is not a valid "PhysicsWorld.DrawTarget".
Added "PhysicsBody.totalForce" and "PhysicsBody.totalTorque" getters and setters.

UUM-144878: PhysicsBody cannot set/get the total torce or torque.
The Rigidbody2D has totalForce and totalTorque allowing both to be set/get. This needs to be available in PhysicsBody.
Retrieved 2026-11-09Added "PhysicsWorld.bounds" property to get the current bounds of all PhysicsShape in the PhysicsWorld.
Added "PhysicsWorld.drawOrder" and "PhysicsWorldDefinition.drawOrder" used to sort the order in which the physics renderer draws world. This provides direct control so you can better visualize multiple worlds; especially important when rendering non-transparent content. In addition, "PhysicsWorld.drawTarget" and "PhysicsWorldDefinition.drawTarget" was added to control if Game view and/or Scene view are rendered to.
Added a small left and right panel padding to the Project Settings page for PhysicsCore2D module so it doesn't touch the window border.
Physics 2D
Added drawing of collision normal (opposite one-way side) for ChainSegmentGeometry.
Added missing definition get/set property from all joints to match all other physics objects.
Added missing physicscore2d Transform / InverseTransform for geometry spans of Circle, Capsule, Polygon, Segment and ChainSegment.
Added missing public argument validation for various Physics Core 2D methods.

Retrieved 2026-11-10Added PhysicsWorld cloning, snapshot and restore. "PhysicsWorld.Clone()" to clone a world, "PhysicsWorld.CreateSnapshot()" to create a complete snapshot of the content of the world and "PhysicsWorld.ApplySnapshot()" to apply a previous snapshot to the PhysicsWorld. Finally, the ability to create a new world with a previous snapshot with "PhysicsWorld.Create(snapshot)" overload.
Added the ability to disable the auto-clearing of custom drawing lifetimes. When a draw command expires, it is typically removed but setting "PhysicsWorld.autoClearCustom" to false will mean the drawing persists until you explicitly call "PhysicsWorld.ClearDraw()".
Applying a very large wind force via PhysicsBody.ApplyWind, or a very large impulse via PhysicsWorld.Explode, could silently corrupt the entire physics world with NaN or Infinity values.
