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
[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.
System.NotImplementedException: Unimplemented Instruction Extension Tail_error when the code contained tail-calls.
Burst: Prevented Burst emitting errors even when Burst was disabled via the
--burst-disable-compilationcommand 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)
