com.unity.entities 1.2.0-pre.12 Package Notes

A file with the code for both snippets in the custom transforms documentation was added to the "DocCodeSamples.Tests" folder.
The Create Menu now offers ScriptTemplates for the IComponentData, ISystem, IJobEntity and Baker types under Assets/Create/Entities

Fixed infinite loop that could occur due to concurrent use of non-concurrent Dictionary in Aspect Generator.
Reduce the set/restore frequency of the fixed rate system group allocator.
Various performance improvements in baking. Baking mesh-heavy scenes now takes 70% of what it did before.
Significant performance improvements when creating archetypes and entity queries in Worlds with a large number of existing archetypes/queries.
Updated Burst dependency to version 1.8.12

EntityQuery singleton methods now correctly handle cases where the query contains enableable components. Note that `GetSingletonEntity()` and `TryGetSingletonEntity()` still can not be used on queries with enableable components, and that the singleton component itself can not be enableable. Both constraints may be lifted in a future release.
A broken link to a code snippet in the documentation for custom transforms was fixed.
Archetype window and Entity Memory Profiler module UI initialization.
Making a player build with define `UNITY_DOTS_DEBUG`, while using an IJobEntity using RefRO/RefRW no longer compile errors!
Clarified documentation for cleanup components
Fixed minor memory leak in content delivery system.
AABB.Contains.
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.
