2021.1.5f1 Release Notes
- Burst: Known issue with Windows Native Debuggers and Dll numbers + workarounds.
License: Disabled package entitlement feature.
Package: Added version increased to 1.16.19.
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.
Android: Fixed freeze when using blend shapes with compute skinning on some devices with Mali G78 GPU. (1298373)
Animation: Fixed StateMachineBehaviour callback been called when playable is paused. (1321298)
Asset Import: Texture Importer no longer secretly defaults values to a negative. (1204566)
Asset Pipeline: The main object name is now updated as appropriate when moving/renaming a file. (1210886)
Asset Pipeline: Unity version no longer written to serialized artifact files generated during asset importing. This was causing inconsistency import result across Unity versions. For existing projects, you must either do a "Reimport All" or delete the library folder for this fix to take effect. (1310981)
Burst: Broken link restored for known issues with debugging and profiling.
Burst: Fixed a bug where the multi-CPU dispatcher (used for player builds targetting multiple CPU architectures) could end up generating invalid instructions.
Burst: Fixed an issue where PDB debug information for instance methods that also used struct return were incorrect.
Burst: When generating Line Table only debug information, an unreachable could occur due to a missing check.
Editor: Fixed files in Packages folder getting moved to Assets when dragging in the Project Browser. (1319052)
Editor: Removed blue line appearing in Editor debug build Inspector windows while hovering between components and without a dragging action. (1323348)
Graphics: Fixed a crash when loading old asset bundles that contain shaders compiled with Vulkan. (1308947)
Graphics: Fixed allocations errors with EncodeNativeArrayToEXR/PNG/JPG. (1315246)
Kernel: Atomic 64-bit Load/Store on Win32/UWP x86 fixed (Reads and writes to 64-bit values are not guaranteed to be atomic on 32-bit Windows).
Kernel: Stop using recently deprecated timer native functions on Mac/iOS/tvOS and replace with current official recommendation.
Linux: Fixed Mouse.position showing coordinates in the window space the mouse was over, instead of the game view. (1318271)
Package Manager: Fixed an issue where Git dependencies using annotated tags for revisions could not be resolved. (1325920)
Particles: Removed 2 decimal point restriction from Duration property. (1319730)
Physics: Ensure that when using 'Physics2D.Distance()' where one of the colliders is an EdgeCollider2D with an adjacent start/end point, that the correct distance points and normal are calculated. (1321270)
Physics: Fixed an issue with setting Surface Penetration to 0 on objects that were authored on one scale but used with another. This would manifest itself as incorrect particle separation behavior. (1319488)
Physics: Fixed Character Controller ignoring other Colliders sometimes. (1279841)
Physics: Stop a crash happening when calling 'Rigidbody2D.ClosestPoint()' on an inactive Rigidbody2D. (1327333)
