2023.1.11f1 Release Notes


  • Burst: Add support for Math.Clamp (this API is available when Api Compatibility Level is set to .NET Standard 2.1).

  • Burst: Added ability to support hashing against different target frameworks.

  • Burst: Added support for default interface methods.

  • Burst: Added support for string interpolation in exception messages.

  • Editor: Improve performance when fetching artifacts that are missing (e.g link to an artifact deleted from the project). (UUM-22002)

  • Mono: Added logging that will now list the threads that are being waited on during a domain reload.

  • Scripting: Reduces noise in logs by setting logging level to 'Debug' in AssemblyUpdater when collecting ApiUpdater configurations. (UUM-45511)


  • Burst: Direct call is now correctly disabled for methods that are decorated with both [BurstCompile] and [UnmanagedCallersOnly] attributes (such methods shouldn't be called directly from managed code).


  • Android: Fixed custom keystore creation via the keystore manager. (UUM-46300)

  • Burst: Fixed a compile-time performance regression in 1.8.7 that could result in slower Burst compilation and increased memory usage during compilation.

  • Burst: Fixed a possible source of invalid alignment, avx2 storing to stack was given a slot with the wrong alignment.

  • Burst: Fixed burst not being able to find external function leading to crashing the Editor.

  • Burst: Fixed Burst sometimes returning wrong value for static readonly fields or static constructors.

  • Burst: Fixed compiler crash when compiling different assemblies that define methods or types with the exact same name and namespace.

  • Burst: Fixed error when trying to use direct call to a nested protected class.

  • Burst: Fixed that converting a negated unsigned type to a float would produce a mismatching value in Burst versus .Net/Mono.

  • Burst: Fixed that jobs wouldn't be Burst compiled for player builds with high stripping.

  • Burst: Fixed that the Burst Inspector handled negation of unsigned types differently than .Net for static readonly fields or static constructors.

  • Burst: Fixed using Armv9 target in the Burst Inspector not formatting the assembly.

  • Burst: Fixed wrong alignment for v128 when doing an indirect access.

  • Burst: Fixed System.NotImplementedException: Unimplemented Instruction Extension Tail_ error when the code contained tail-calls.

  • Burst: Fixed uint to float conversion edge-case.

  • Burst: Prevented Burst emitting errors even when Burst was disabled via the --burst-disable-compilation command line option.

  • Burst: Under some conditions (if the error in compilation occurred in a location that didn't have valid debug information), building a player might not generate any files, and not display any errors.

  • Documentation: Updated "Applying default presets to Assets by folder" documentation example to prevent an import infinite loop. (UUM-44046)

  • Editor: Editor: Fixed incorrect launch screen scaling on Windows scaled 200%. (UUM-31767)
