Changes ComponentGroup.Types was made internal, since it will likely be refactored Renamed DynamicBuffer.GetBasePointer() to DynamicBuffer.GetUnsafePtr() for consistency with NativeArray API. Fixes Component types no longer show up multiple times in archetypes and queries in the EntityDebugger Attempting to rename an entity in the EntityDebugger no longer causes an exception (naming is not yet supported) Component filter editor now shows types in consistent alphabetical order when filtering The Show button in the GameObjectEntity inspector works again Fixed [ReadOnly] DynamicBuffer incorrectly throwing exceptions when getting the NativeArray inside of a job. Fixed DynamicBuffer not throwing the right exceptions when writing to buffers while NativeArrays are being used in jobs https://github.com/Unity-Technologies/EntityComponentSystemSamples/blob/master/ReleaseNotes.md A few other things I noticed - ArchetypeChunkArray added DidAddOrChange, GetComponentVersion and Has methods for buffers - EntityManager ComponentDataFromEntity, BufferFromEntity made internal.
