2019.4.28f1 Release Notes

Improvements

  • 2D: Tilemap.GetSprite now returns the currently animated Sprite for an animated Tile instead of the initially set Sprite.

  • IL2CPP: Correctly provide the source file hash so that a managed debugger can determine when a source file has changed and provide a proper warning.

  • Package Manager: Corrected provide the source file hash so that a managed debugger can determine when a source file has changed and provide a proper warning.

Changes

  • Android: Updated Android Logcat package to version 1.2.2.

  • Package: Updated Addressables package to version 1.16.19.

  • Package: Updated com.unity.ide.visualstudio package to version 2.0.8.

  • Package: Updated com.unity.purchasing package to version 3.0.1.

  • XR: Updated Oculus XR Plugin package to version 1.9.1.

Fixes

  • 2D: Fixed initial rendering animated tiles when a CompleteObjectUndo is registered for a Tilemap while in Play mode.

  • 2D: Fixed wrong Sprites being shown for Animated Tiles when TilemapRenderer is in Individual mode and user sets new Tiles on the Tilemap. (1329054)

  • Android: Fixed crash on startup on Android 4.4 devices. (1331290)

  • Animation: Fixed an issue where the animator parameter values would truncate float values to 1 decimal. (1308930)

  • Asset Import: Fixed infinite asset import loop during InitializeOnLoad when Editor script uses CreateAsset and importParameters change during import. (1323499)

  • Burst: Fixed a crash that was caused by member function debug information on tvOS.

  • Burst: Fixed an UnauthorizedAccessException that could occur when using Burst in players built for the macOS App Sandbox.

  • Editor: Added System.IO.Compression to reference assemblies when targeting .NET 4.7.1 (editor only contexts). (1275859)

  • Editor: Fixed items in right click menu doing nothing on arrays in scriptable object with custom editors. (1307389)

  • Graphics: Fixed a crash when loading old asset bundles that contain Vulkan shader binaries. (1308947)

They will now only occur when switching back-and-forth between a built-in microphone and a Bluetooth microphone. When using "Prepare iOS for Recording", most projects will also want to set "Force iOS Speakers when Recording". (1281833)

  • Kernel: Fixed an issue with Atomic 64-bit Load/Store on Win32/UWP x86. Reads and writes to 64-bit values are not guaranteed to be atomic on 32-bit Windows.

  • Package Manager: Fixed an issue which could sometimes lead to missing files in successfully resolved packages in projects with a large number of packaged assets.

  • Package Manager: Fixed an issue which prevented starting UnityPackageManager.exe on Windows when its path contained non-ANSI Unicode characters. (1317244)
