[1.1.0] - 2026-09-11

All PhysicsArea now support shape-based "PhysicsCallbacks.IPreContactCallback" and "PhysicsCallbacks.IPreContinuousCallback" which allow contact rejection and manifold changes.
All PhysicsArea now support areas-based "PhysicsAreaCallbacks.IPreContactCallback" and "PhysicsAreaCallbacks.IPreContinuousCallback" which allow contact rejection and manifold changes.

The pre-contact and pre-continuous dispatch counters shown in the "Info" fold-outs no longer undercounting, because those callbacks arrive on worker threads.
Stopped an InvalidCastException being thrown from the Pose and Simulation inspectors when entering Play mode.
PhysicsWorld custom Transform Plane is now fully supported by all PhysicsArea.
Prefab editing now works with isolated worlds and supports multiple world simulations simultaneously in the same prefab. In addition, nested prefabs now work.

Initial release of 2D Physics Core, providing supported components for the PhysicsCore2D features in Unity.
