Logging done in imports run in an import worker is now forwarded to the main editor log.
Asset PipelineImprovement
Logging in import worker will now always log to local import worker log file.
Asset PipelineImprovement
Added an API to gather the lighting and fog modes used by the active scene.
Build PipelineImprovement
Added a new API InternalEditorUtility.LoadSerializedFileAndForgetAsync which loads a serialized file on the preload thread.
EditorImprovement
Added Profiler.EmitSessionMetaData api to pass generic metadata to the Profiler associated with profiling session.
ProfilerImprovement
Added Developer-only toggle to view Preview Scenes on the hierarchy for debugging purposes.
Scene ManagerImprovement
Added flags to support certain GameObject features in Preview Scenes (Events, GI Lights and Cameras).
Scene ManagerImprovement
Added a new AsyncReadManager FileInfo() API to check for a file's existence and (if present) the file size.
ScriptingImprovement
Added atomic safety handle boolean validation functions to AtomicSafetyHandle.bindings.cs
ScriptingImprovement
Fixed incorrect JobsDebugger handling of C# "readonly" keyword.
EditorFix
Fixed: Unity.IO.LowLevel.Unsafe.ReadStatus.Truncated result for completion of a truncated read. A truncated read occurs when an asynchronous file request attempts to read beyond the end of a file.
ScriptingFix
Fixed: Unity.IO.LowLevel.Unsafe.ReadStatusExtension methods - Unity.IO.LowLevel.Unsafe.ReadStatusExtension.Complete() returns true on successful completion regardless of truncated file reads.
ScriptingFix
Updated NativeArray and NativeSlice Enumerator MoveNext functions with a define conditional atomic safety handle boolean check to ensure that existing enumerators return false when MoveNext() is called instead of throwing an exception.
