2021.2.19f1 Release Notes

Features

• Version Control: Added checkout option in scene prefab view.

API Changes

• 2D: Added: Added Tilemap.GetTilesBlockNonAlloc API.

Changes

• Version Control: Updated file overlay icon size to adapt to project window zoom level.

• Version Control: Updated the styling of number of items in a category in Gluon incoming changes view.

Fixes

• Android: Fixed an issue where add PlayCore dependency was added to build.gradle file if it was already added to the project as an .aar file. (1374774)

• Build Pipeline: Fixed an issue where BuildPlayerOptions.assetBundleManifestPath to be used when building player was not allowed. (1399616)

• Burst: Fixed a bug when calling profiling CreateMarker on iOS, Burst could fail at runtime saying it was unable to find CreateMarker__Unmanaged.

• Burst: Fixed a issue where burst was enabled in secondary Unity processes, including the asset import worker and out-of-process profiler (see changelog entry for 1.6.0-pre.1 for more context around this).

• Burst: Fixed an access violation error that could occur when reading from a static readonly variable.

• Burst: Fixed an exception that could occur if you had the Burst AOT Settings menu docked in the Editor, and then did a player build. Trying to change any of the Burst AOT Settings would throw an exception (unless you closed and reopened the Burst AOT Settings).

• Burst: Fixed an issue where codegen differences could occur when using a local vector variable that was being captured by reference and passed to a called function, versus when it wasn't.

• Burst: Fixed an issue where if there were two generic structs overlapping at the same FieldOffset in an explicitly laid out struct, a codegen error would occur.

• Burst: Fixed an issue where if you used FloatMode.Fast with math.pow, where the y argument to math.pow was actually sourced from an integer, illegal codegen would be generated (LLVM would try and call out to powf from the cstdlib).

• Burst: Fixed another rare case of the file-is-locked bug where the Burst IL Post Processor could incorrectly hold a file lock on a pdb.

• Burst: Fixed errors when working with paths containing special characters.

• Burst: Fixed the Burst link.xml output to preserve C# methods we rely on, alongside the static constructors that we preserved previously.

• Burst: Improved UWP linker error message to clarify which VS components need to be installed for UWP.

• Burst: Made --burst-force-sync-compilation command-line option actually work.

• Editor: Fixed a NullReference when showing UnityEvent popup and the GameObject contained a component with a missing script. (1388739)

• Graphics: Fixed a hang on repeated calls to GraphicsBuffer.CopyCount,. (1353308)

• Graphics: Fixed an issue where uniforms in ray tracing hit shaders that were not set by the user would cause wrong uniform values in other hit shaders. (1407052)

• Graphics: Improved to CullScene performance; in large scenes (10000+ Renderers) this can halve the time spent in CullScene. (1399880)

• IL2CPP: Fixed an issue in which using PlayerSettings.SetAdditionalIl2CppArgs was set to multiple arguments would not work. (1379270)

• Linux: Fixed "Project Setttings" and other menu items being disabled after a script recompliation. (1380015)

• Mono: Fixed an issue where the mono executable would be run via rosetta instead of natively on apple silicon. (1379951)

• Profiler: Fixed an issue where Custom Profiler categories were not enabled as required by the Profiler window when used in one or more modules.. (1367356)

• Shaders: Fixed an issue where HLSLcc was not using half precision temps when multiple half precision sample instructions targeted the same temp register. (1383901)

• UI Toolkit: Fixed an invisible VisualElement with UsageHints.GroupTransform set would not apply its transform to its visible descendants. (1402057)

• UI Toolkit: Fixed an issue where there was a reduction of GPU performance of the UIToolkit shader. (1361737)

• URP: Fixed an intermediate texture mode SSAO compatibility issue and updated default intermediate texture mode to always.

• Version Control: Fixed a toolbar icon issue that was not displaying incoming change notifications when the Plastic window was closed.

• Version Control: Fixed an error when trying to invite members to proect.

• Version Control: Fixed an issue where there were editor unhandled errors being hijacked by the plugin.
