Burst: In versions of Unity older than 2019.3, changing the following options in the Burst menu now requires the Editor to be restarted: Enable Compilation, Safety Checks, and Native Debug Mode Compilation. In versions of Unity older than 2019.3, previously-compiled methods will not be recompiled after changing those options, which could lead to undefined behavior where methods may or may not be compiled with the correct options. This change removes that possibility.
Burst: Made the compiler better at constant-folding complex static readonly constructors.
Burst: The Burst Inspector no longer uses JIT compilation. The code it shows is now compiled the same way as for editor / player usage.
Burst: The Burst menu-item

Safety Checkshave been reset to

Editor: Scene/Game view Gizmos dropdown window now has a search field. (1274775)
Editor: Two new events added to ObjectSelector: ObjectSelectorSelectionDone: An item in the list is double-clicked; and ObjectSelectorCanceled: The window was closed by explicitly pressing escape on the keyboard.
GI: Hiding Enlighten specific settings when it is not supported by the SRP. Affected areas are Mesh Renderer, Light, Scene view, Lighting Explorer and Lightmap Parameters.
Graphics: Improved compression speed for ASTC textures.
Graphics: Optimized static batching process, e.g. entering play mode with 30k static batched objects in the editor is faster by two seconds.
IL2CPP: An IL2CPP failure will now result in one (instead of two) error messages. The error message text will be displayed with as little extra information as possible, so that the error is (hopefully) more understandable.
IL2CPP: When script debugging is enabled, stack traces will now include C# source code line numbers for all assemblies where debug symbols are available.
Networking: Make UnityWebRequest objects properly show up in profiler. (1017004)

Scripting: GameObject.FindGameObjectWithTag and GameObject.FindGameObjectsWithTag are much faster.
Shaders: #pragma require now works from compute shaders as well.
SpeedTree: A Fix button now will appear in Mesh Renderer and LOD Group component inspector if Unity detects wrong SpeedTree shader is used (for instance Nature/SpeedTree8 shader is used for meshes that come from SpeedTree 7 assets, and vice versa), and will correct them if clicked. (1237736)
Terrain: Now a "Hole Edge Padding" option is added to terrain Detail Prototype that you can control how far details objects will be from the hole edge.
Terrain: Reduced Terrain per-frame CPU update cost.
Version Control: Smart Merge (UnityYamlMerge) now allows ignoring "tiny" float differences in some fields. For a configuration example, see mergerules.txt. (1211899)

[BurstCompile(DisableSafetyChecks = true)]that allows per job or function-pointer disabling of safety checks. This allows users to have blessed code run fast always.
Burst: Add intrinsics support for
Burst: Add support for try/finally and using/foreach for IDisposable patterns.
Burst: Added a compiler warning for any use of throwing an exception from a method not guarded by
[Conditional("ENABLE_UNITY_COLLECTIONS_CHECKS")]. Since exceptions in Burst are only supported in the editor, this provides a useful warning to users who may be relying on try/catch behaviors for control-flow which is not supported in final game builds.
Burst: Added first batch of Arm Neon intrinsics. Currently, only ArmV8 (AArch64) targets are supported. The supported intrinsics include all ArmV7 and ArmV8 ones.
Burst: An error message if attempting to BurstCompiler.CompileFunctionPointer() on a multicast delegate, since this is not supported in Burst.
