com.unity.entities 1.2.1 Package Notes

The entities hierarchy view would sometimes throw exceptions when entities were destroyed.
remove use of UNITY\_64 define, as is can not be reliably used to determine 64 bit nature of platforms. Fixes crashes related to pointer truncation.
The inspector no longer shows stale content when exiting play mode while locked in Authoring mode on a GameObject outside of a subscene.
Systems now correctly track the implicit read dependency on enableable components in their queries' `Any` lists. These components are optional, but evaluating a query with optional enableable components requires reading these components' enabled state, which requires a read dependency even if nothing else in the system directly manipulates these types.
`EntityManager.SetComponentEnabled(EntityQuery,bool)` now sets the change version for the target type `T` on all affected chunks.
`CompanionGameObjectUpdateTransformSystem` expected entities to have the `LocalToWorld` and `CompanionLinkTransform` components, but did not explicitly require them in its query.
