New 2021.2.0a15 Entries since 2021.2.0a14


  • Burst: Added a new OptimizeFor mode Balanced. This becomes the default optimization mode, and trades off slightly lower maximum performance for much faster compile times.

  • Burst: Added an OptimizeFor option to [BurstCompile], allowing users to say they want fast code, small code, or fastly compiled code.

  • Burst: Added experimental half precision floating point type f16.

  • Burst: Added experimental support for half precision floating point Arm Neon intrinsics.

  • Burst: Added source location metadata into hash cache.

  • Burst: Added support for having [return: MarshalAs(UnmanagedType.U1)] or [return: MarshalAs(UnmanagedType.I1)] on a bool return external function.

  • Burst: Added support for the C# 8.0 construct default(T) is null to Burst by transforming the generated Box + 'is the box non-null?' at compile time.

  • Burst: Added workarounds for known issue with Windows Native Debuggers and Dll numbers.

  • Burst: An additional warning about delegates being used by BurstCompiler.CompileFunctionPointer that are not decorated as expected. In most cases, Burst will automatically add the C-declaration attribute in IL Post Processing, but if the usage of CompileFunctionPointer is abstracted away behind an open generic implementation, then Burst will not be able to automatically correct the delegate declaration, and thus this warning will fire.

  • Burst: Assemblies are now allowed to have an [assembly: BurstCompile()] attribute to let users specify compile options that should apply assembly wide (for instance [assembly: BurstCompile(OptimizeFor = OptimizeFor.FastCompilation)]).

  • Burst: Automatically add [UnmanagedFunctionPointer(CallingConvention.Cdecl)] to any delegates that are used for BurstCompiler.CompileFunctionPointer<>() or error if the delegate has the attribute and it is not Cdecl.

  • Burst: Can now call BurstCompiler.CompileFunctionPointer() in Burst code.

  • Burst: Intrinsics: Neon - Added support for basic vld1 APIs.

  • Burst: New AotNativeLinkEmbeddedLinux for EmbeddedLinux.

  • Burst: New burst_TargetPlatform_EmbeddedLinux.

  • Graphics: Introduced a tool to help set the bounds of a VFX.

  • Package: Polybrush 1.1.2.

  • Particles: Added a mesh weighting field to the list of meshes, to control how many of each mesh to use.

  • UI Toolkit: Added support for up to 7 levels of stencil-based masking.

  • UI Toolkit: Added the contextual action of unpacking a template in a document in the UI Builder (UI Builder).

  • Editor: Optimized drag selection in Editor scenes.

  • Editor: Transform component Scale inspector field got the ability to constrain scale proportions. There's also an editor preference whether newly created objects should have constrain proportions scale on by default.

  • GI: Added asynchronous environment sky updates for realtime GI, avoiding frame hitches whenever the sky changes.

  • Graphics: Improved performance of ASTC decompression by using multi-threading (around 6x using 8 threads).

  • Package: Updated Addressables package to 1.17.17.

  • Package: Visual Scripting - Improved migration tools to allow users to migrate their project to recent Visual Scripting version.

  • Scripting: Multithreaded asset garbage collection and increased speed by up to 2.5x.

  • UI: Reused PropertyFields backing fields when possible.

  • UI Toolkit: Set UIDocument's execution order to -100 to ensure root visual element is created when user's OnEnable runs.

API Changes

  • Android: Added: TargetDevices player setting, so users can select if they want their Android application to run on all devices, just Android phones, tablets, and TV devices, or just Chrome OS devices.

  • Graphics: Added: Rendering.SupportedRenderingFeatures.reflectionProbesBlendDistance to provide SRPs with the ability to enable the blend distance fields in the ReflectionProbe inspector.

  • Graphics: Added: ReflectionProbe.UpdateCachedState() to update the internal data related to reflection probe used by the culling system.

  • Terrain: Changed: IOnInspectorGUI ShowBrushGUI overloads removed and replaced with a single ShowBrushGUI call with default parameters.

  • Terrain: Changed: TerrainAPI namespace is no longer part of an experimental namespace and has been renamed TerrainTools.

  • Terrain: Changed: TerrainPaintTool GetDesc changed to GetDescription.

  • Terrain: Changed: TerrainUtility moved to UnityEngine.TerrainUtils namespace.

  • Terrain: Changed: TerrainUtility.TerrainMap moved to UnityEditor.TerrainUtils.TerrainMap. TerrainMap.TileCoord moved to UnityEditor.TerrainUtils.TerrainTileCoord.

  • Terrain: Changed: UnityEditor.TerrainAPI.TerrainPaintUtilityEditor.BrushPreview changed to UnityEditor.TerrainTools.TerrainBrushPreviewMode.

  • UI Toolkit: Added: Expose ScrollView.mode property.


  • 2D: Tile.StartUp is called after Tilemap is loaded instead of on the first Update after Tilemap is loaded. (1327583)

  • Android: Show Require ES3.1, Require ES3.1+AEP, Require ES 3.2 checkboxes in Android PlayerSettings when "Auto Graphics API" is enabled.

  • Burst: Armv8.2 Neon intrinsics are now fully supported.

  • Burst: Changed Burst minimum editor version to 2019.4.

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

  • Burst: Changed how SLEEF global variables for trig functions are pulled into Burst to reduce duplications.

  • Burst: Changed how we resolve function references in the compiler to improve resolving an existing function reference by 3x.

  • Burst: Changed our link step to not use response files if the command line was smaller enough, saving the cost of the round-trip to the disk.

  • Burst: Constant array data is now named after the static field it belongs to in assembly.

  • Burst: Disabled threading within the lld linker instances we use for in-editor and desktop cross compilation, because we're already threading seperate process instances of lld and it results in lot of OS context switching.

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

  • 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 how we handle generic resolution in Cecil to cache the strictly resolved generic types and save a bunch of time in the compiler.

  • Burst: Improved iteration speed by reducing the time it takes for Burst to check if any Burst-compilable code has changed.

  • Burst: In order to prevent conflicts with the main Unity process, Burst is now inactive in secondary Unity processes, including the asset import worker and out-of-process profiler. This means that in those secondary processes, code that would normally be Burst-compiled will now run under Mono. In a future release of Burst, we hope to lift this restriction and allow Burst-compiled code to run in secondary Unity processes.

  • Burst: Made half <-> float / double conversions use native hardware where possible (Arm or AVX2 targets).

  • Burst: The Unity.Burst.Intrinsics.Common.Pause intrinsic is no longer experimental.

  • Burst: Tweaked how the IL Post Processed 'direct call' Burst function pointers are compiled so that the compilation is deferred until they are needed (previously we'd enqueue them all for compilation on a domain reload).

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

  • Burst: Use rpmalloc as our native allocator on Windows to speed up concurrently executing LLVM work.

  • Burst: When Burst has previously compiled a method, and neither the assembly containing that method nor any of that assembly's dependencies have changed, it was possible after a domain reload for the Mono version of the method to be used for a short time before being replaced by the Burst version. This has now been improved such that the Burst version will be used immediately.

  • Graphics: Do not resize unity_SpecCubeN_BoxMax and unity_SpecCubeN_BoxMin to encompass the bounds of the object itself if an SRP is active.

  • Graphics: Improved quality of RGBM encoded ASTC textures and fallback to ETC2 was removed.

  • Graphics: Unity_SpecCubeN_BoxMax.w now contains the blend distance of the reflection probe.
    unity_SpecCube1_BoxMin.w now contains information on the relative importance between SpecCube 0 and SpecCube1.

  • Graphics: Updated SRP templates to 12.0.0.

  • Services: Removed the "Migrate" button section from In-App Purchasing Settings when com.unity.purchasing version of 2 or less is installed. The migration warning messages are now in the section with the "Latest Version" section.

  • Shaders: Fixed editor crash if shader error db fails to open. (1327429)

  • XR: Fixed XRSettings.occlusionMaskScale not working in SRPs.

  • XR: Fixed XRSettings.showDeviceView not working in SRPs.
