2020.3.30f1 Release Notes
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
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.
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
