• Profiler: Removing the Loading.IDRemapping profiler tag which was causing excessive profiling overhead when loading AssetBundles.

• Profiler: Selections CPU or GPU samples made in the CPU Usage and GPU Usage Profiler Modules now carry over correctly and persistently to all views (Timeline, Hierarchy, Raw Hierarchy) as well as to all frames that contain them. In frames other than the one the selection was originally made in, the selection will point to the first sample that provides the best match to the stack of sample names that lead up to that original sample. So if there are e.g. multiple Components of the same type "MyComponent", and you select the "MyComponent.Update()" sample of one of them, there is no way for the Profiler to identify the "MyComponent.Update()" sample of exactly that sample Component in the next frame. It will therefore just select the very first "MyComponent.Update()" sample it can find. If a part of the Sample Stack is missing in a frame, the selection Tooltip in Timeline or an extra line at the bottom of the Hierarchy views will alert you of the fact, that the selection that was carried over to this frame is just an approximation. An option was added to show the difference in this approximated Sample Stack, and the originally selected Sample Stack. If not even one of the sample names from the original selection fits the samples in a particular frame and thread, no selection will be displayed. If a selection was made on a thread other than the Main Thread, switching to the Hierarchy Views will automatically switch them to the right thread this selection was made in. (1066309)

• Asset Import: Changed Alembic verified package to 2.1.1-pre.1.

• Asset Import: When Meshes have no material defined in the imported file, the ModelImporter will now assign the default material to them rather than creating a 'No name' material sub-asset.

• Burst: Burst enters RC phase.

• Burst: Bursted DOTS Runtime Jobs are now decorated with [NativePInvokeCallback] instead of [MonoPInvokeCallback] which could generate callback wrappers which could cause native code to inadvertently interop with the managed VM.

• Burst: Changed how exceptions throw types and messages are stored in our Burst binaries to reduce binary size.

• Burst: Changed to inliner heuristics to improve build time and reduce executable size.

• Burst: DOTS Runtime shares the logging code path with the general case.

• Burst: Eager-compilation is now cancelled when script compilation starts, to prevent spurious errors related to recompiled assemblies.

• Burst: Exception strings no longer contain the entry-point name of the job/function-pointer that caused the throw. This change was required because the Burst compiler has to produce deterministic results from any given compile, which is fundamentally opposed to per-entry-point function derivations.

• Burst: Improved Burst initialization time.

• Burst: Improved Burst Inspector loading time.

• Burst: Improved eager-compilation performance.

This change removes that possibility.

• Burst: Made the compiler better at constant-folding complex static readonly constructors.

• Burst: Open-generic static methods are not supported by Burst, but they were previously visible in Burst InspectorBurst: they are now hidden.

• 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 Checks has been changed to a modal choice of Off, On, and Force On. Force On will overwrite any user job or function-pointer with DisableSafetyChecks = true. To avoid users falling into the consistent trap of having Safety Checks set to Off, any reload of the Editor will issue a warning telling the user that Safety Checks have been reset to On.

• Burst: The command line option --burst-disable-compilation is now disabling entirely Burst, including the AppDomain.

• Burst: Updated Cross Compilation Tooling To LLVM 10.

• Burst: Upgraded Burst to use LLVM Version 11.0.1 by default, bringing the latest optimization improvements from the LLVM project.

• Burst: Use platform provided memory intrinsics for iOS, tvOS, WASM, and console platforms.

• Graphics: Changed so texture formats DXT1 and DXT5 in the UI labels are now named "DXT1|BC1" and "DXT5|BC3", indicating terminology used by modern graphics APIs.

• Graphics: Changed switch shaders to now use separate samplers instead of combined texture-samplers objects.

• Graphics: ComputeBuffer.IsValid now returns false when compute is not supported and ComputeBuffer.BeginWrite throws InvalidOperationException for invalid ComputeBuffers. (1259525)

• Graphics: Removed postprocessing package from core packages list.

• Scripting: Added support for new managed code stripping annotation attributes.

• Scripting: Added support for Unity Version Defines in Assembly definition import options.
  This feature improvement allows scripts to easily specify different code snippets for different unity version ranges. This is especially useful for introducing calls to newly added public APIs, in which case these API calls needs to be guarded by defines based on a unity version range of a given unity version or later.
  Unity version range expression syntax is the same as package version range expressions. Unity version format differs from package version format, thus Unity version expressions are evaluated based on some rules specific to the Unity version format:
  

  • Comparison of release types follows the following rules: a<b<f=c<p<x. So eg. an alpha version is always smaller (earlier) than a beta version, regardless of the Incremental version.
    
  • The unity versions are allowed to have suffixes (e.g 2020.1.3-bonfire) which are ignored by the unity version comparison code
    
  • Chinese releases are equivalent to public releases (f) so for the sake of comparison in the version range expression 2020.1f3 would be equal to 2020.1c3[
    
  • experimental releases don't include an Incremental Version - e.g. everything after 2020.2.1x would be treated as suffix and ignored by the version comparison.

• Scripting: Changed Roslyn Analyzers to be run part of normal Compilation Step.
  This will also result in Analyzer errors to be treated as an Compile Error.

• Scripting: GameObject.FindGameObjectWithTag and GameObject.FindGameObjectsWithTag are much faster.

• Package Manager: Package Manager: 'Release Candidate (RC)' packages will no longer be tagged as such for users on release builds- it was decided that it's confusing for users to see a tag different from the version tag (-pre), so release builds just tag RC packages as Pre-Release now. Users on Developer builds still see RC packages tagged as RC.

• Package Manager: Removed 'See all versions' option in version list for external users, added Project Setting for internal users to re-enable this option.

• Package Manager: Updated Package Manager UI version tags for new Lifecycle and logic for recommending/showing available versions to users.
