### 6000.5.9f1 Release Notes

#### API Changes

- Editor: Added: Project Auditor: add migration areas so we can add migration rules.



#### Fixes

- Accessibility: Fixed `AssistiveSupport.screenReaderStatusChanged` not being supported by Narrator \(the Windows built-in screen reader\).
    ([UUM-147175](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-147175))

- AI: As a result of an unsupported configuration, a NavMeshAgent would try to separate from its own NavMeshObstacle component by jumping in arbitrary directions. Now the agent moves in one stable direction.
    (UUM-141803)

- AI: NavMeshAgents created or teleported inside box NavMeshObstacles could not move out of the obstacles.
    ([UUM-146477](https://issuetracker.unity.com/api/v1.0/redirects/guid/UUM-146477))
