2020.3.30f1 Release Notes

Improvements

• Asset Pipeline: Logging done in imports run in an import worker is now forwarded to the main editor log.

• Asset Pipeline: Logging in import worker will now always log to local import worker log file.

• Build Pipeline: Added an API to gather the lighting and fog modes used by the active scene.

• Editor: Added a new API InternalEditorUtility.LoadSerializedFileAndForgetAsync which loads a serialized file on the preload thread.

• Profiler: Added Profiler.EmitSessionMetaData api to pass generic metadata to the Profiler associated with profiling session.

• Scene Manager: Added Developer-only toggle to view Preview Scenes on the hierarchy for debugging purposes.

• Scene Manager: Added flags to support certain GameObject features in Preview Scenes (Events, GI Lights and Cameras).

• Scripting: Added a new AsyncReadManager FileInfo() API to check for a file's existence and (if present) the file size.

• Scripting: Added atomic safety handle boolean validation functions to AtomicSafetyHandle.bindings.cs

Fixes

• Editor: Fixed incorrect JobsDebugger handling of C# "readonly" keyword.

• Scripting: Fixed: Unity.IO.LowLevel.Unsafe.ReadStatus.Truncated result for completion of a truncated read. A truncated read occurs when an asynchronous file request attempts to read beyond the end of a file.

• Scripting: Fixed: Unity.IO.LowLevel.Unsafe.ReadStatusExtension methods - Unity.IO.LowLevel.Unsafe.ReadStatusExtension.Complete() returns true on successful completion regardless of truncated file reads.

• Scripting: Updated NativeArray and NativeSlice Enumerator MoveNext functions with a define conditional atomic safety handle boolean check to ensure that existing enumerators return false when MoveNext() is called instead of throwing an exception.

• Graphics: Fixed a NativeArray de-allocation error when using the results of Texture2D.GetPixelData in multiple jobs per frame. (1359263)

• Graphics: Fixed an issue that Texture Memory in Memory Profiler Module was not updated when profiling a Vulkan build. (1351803)

• Graphics: Fixed an issue where memory would leak from mesh due to mismatching memory labels. (1362505)

• Graphics: Fixed incorrect compression of 8k ETC textures using the Crunch compressor. (1346908)

• Input System: Fixed a performance issue on entering/exiting play-mode where HID device capabilities JSON could be parsed multiple times for a single device. (1362733)

• Input System: Fixed a problem where explicitly switching to the already active control scheme and device set for PlayerInput would cancel event callbacks for no reason when the control scheme switch would have no practical effect. This fix detects and skips device unpairing and re-pairing if the switch is detected to not be a change to scheme or devices. (1342297)

• Input System: Fixed a problem where only using runtimes that are not XR supported causes a compile error. This fix adds back in ENABLE_VR checks to prevent this issue.

• Input System: Fixed an error "Default constructor not found for type UnityEngine.InputSystem.iOS.LowLevel.iOSStepCounter" and any other potential exceptions due to classes, methods, fields and properties being stripped when managed stripping setting is set to medium or high. (1368761)

• Input System: Fixed an incorrect generic gamepad short display button names mapping.

• Input System: Fixed an issue where InvalidOperationException is thrown if an input for an action with multiple interactions is held while disconnecting the device. (1354098)

• Input System: Fixed an issue where resetting an action via InputAction.Reset() while being in disabled state would prevent the action from being enabled again. (1370732)

• Input System: Fixed current being null for sensors (Accelerometer.current, others). (1371204)

• Input System: Fixed handling of exception in InputManager.OnUpdate and now the system will try to handle the exception and recover into a working state.

• Input System: Fixed input action for Android gamepad's right stick will be correctly invoked when only the Y-axis is changing. (1308637)

• Input System: Fixed action.ReadValue and others returning invalid data when used from FixedUpdate or early update when running in play mode in the editor. (1368559)

• Input System: Improved the user experience when creating single vs multi-touch touchscreen bindings in the Input Action Asset editor by making both options visible in the input action dropdown menu. Now it's not neccessary to be aware of the touch\*/press path binding syntax. (1357664)

• iOS: Fixed a crash/hang when going to background from portrait upside down. (1285042)

• Particles: Fixed an issue that texel size and mask interaction shader properties are missing in the particle system renderer. (1296392)

• Profiler: Fixed a rare crash on Editor shutdown. (1372546)

• Profiler: Fixed an ArgumentOutOfRangeException in the Module Editor when enabling deep profiling after deleting a module. (1335309)

• Serialization: Fixed an issue that classes referred by value will also be considered and added to the list of classes not to be stripped when performing a Player Build / Asset Bundle Build / Addressable Build, in addition to SerializeReference. (1296195)

• Serialization: Fixed missed invocations of ISerializationCallbackReceiver.OnAfterDeserialization and asserts arising when that interface is implemented on structs inside a MonoBehaviour or ScriptableObject class, along with the presence of SerializeReference fields. (1372710)

• Shaders: Fixed an issue with Editor using some default data until a shader is imported or compiled. (1369645)

• uGUI: Fixed an issue where the text inside a Canvas would sometimes blink.

• Universal Windows Platform: Fixed a building issue and now generated Visual Studio project builds correctly on Universal Windows Platform with Visual Studio 2022. (1378086)

• Video: Fixed spamming errors in the Console when opening imported video in the Inspector tab and Target Platform is set to UWP. (1357597)

• Windows: Fixed an issue where files get locked unnecessarily by UnityCrashHandler.exe no longer inherits all Windows handles from the editor/player when launched.

• XR: Fixed an issue where duplicated UnitySubsystemsManifest.json files were added while building XR app for Android with Build App Bundle option.

• XR: Fixed an issue with the XR plugin interface depth. (1376203)

System Requirements

For development

OS: Windows 7 SP1+, 10, 64-bit versions only; macOS 10.13+. (Server versions of Windows & OS X are not tested.)

CPU: SSE2 instruction set support.

GPU: Graphics card with DX10 (shader model 4.0) capabilities.

The rest mostly depends on the complexity of your projects.

Additional platform development requirements:

• iOS: Mac computer running minimum macOS 10.13+ and Xcode 9.0 or higher.

• Android: Android SDK and Java Development Kit (JDK); IL2CPP scripting backend requires Android NDK.

• Universal Windows Platform: Windows 10 (64-bit), Visual Studio 2015 with C++ Tools component or later and Windows 10 SDK

For running Unity games

Generally content developed with Unity can run pretty much everywhere. How well it runs is dependent on the complexity of your project. More detailed requirements:

• Desktop:

  • OS: Windows 7 SP1+, macOS 10.13+, Ubuntu 18.04+
  • Graphics card with DX10 (shader model 4.0) capabilities.
  • CPU: SSE2 instruction set support.

• iOS player requires iOS 11.0 or higher.

• Android: OS 4.4 or later; ARMv7 CPU with NEON support; OpenGL ES 2.0 or later.

• WebGL: Any recent desktop version of Firefox, Chrome, Edge or Safari.

• Universal Windows Platform: Windows 10 and a graphics card with DX10 (shader model 4.0) capabilities

• Exported Android Gradle projects require Android Studio 3.4 and later to build
