2020.3.35f1 Release Notes

Features

  • Asset Pipeline: Added accelerator Corruption Detection.

Improvements

  • Android: Added Initial launch size metadata into AndroidManifest.xml for Chrome OS devices with Android R or higher installed. (1360064)

  • Asset Import: Upgraded boost::asio version to v1.20.0. (1408567)

  • Editor: Improved the drag & drop speed in the Project view on large projects. (1314065)

  • Input System: Touch input can now be handled from USB secondary capacitive touch screens on Android.

  • Mobile: Added a new Player setting "Reset resolution on window resize" to reset resolution when native window is resized. (1393410)

  • Scripting: Added automatical retry for file copy exception when running ILPPs is thrown.

  • Shaders: Added buildTarget property to ShaderCompilerData struct. (1403750)

Fixes

  • 2D: Fixed a case of Null Referrence Exceptions when Packing a Sprite Atlas with size smaller than the smallest Sprite. (1416307)

  • 2D: Fixed an issue when Skinning Editor will lose reference after exiting Play mode. (1405289)

  • Android: Fixed a Unity Audio bug related to Bluetooth audio. This was causing issues with Vivox, and possibly other 3rd part audio libraries, with Bluetooth functionality. On Android, Bluetooth audio state is basically global, so Unity Audio now only makes the bare minimum changes to this state. We may still call startBluetoothSco and stopBluetoothSco when starting or re-initializing the audio output engine and when starting/stopping the Unity microphone. We may also call AudioManager.setMode when starting/stopping a Bluetooth mic through the Unity microphone APIs, but that's it. (1418634)
