Unity

What's new in this version:

Fixes:
- Asset Bundles: Fixed an edge case with AssetBundle.Contains not returning true for case sensitive paths
- Editor: Context menus that are deeper than root level are not removed.
- Editor: Fixed Screen.resolutions returning 0 length collection in the Linux editor
- Editor: Fixed the issue with Foldout click rect not aligning with the icon.
- GI: Fixed lightmappers carrying over stale state when switching scenes
- Graphics: Fixed missing memory barrier when image is repeatedly bound for writing between dispatch calls
- Graphics: Prevent memory leak of Command Buffers on Metal devices
- iOS: Fixed storyboards sometimes still rotating to forbidden orientations on iOS 13+
- Mobile: Adaptive Performance - Added workaround to send temperature warning when the device starts as warm already as currently no events are sent
- Mobile: Adaptive Performance - Automatic Performance Mode: lower CPU and GPU levels at the same time instead of one at a time to increase efficiency and higher power savings
- Mobile: Adaptive Performance - Fixed Automatic Performance Control flag to respect the function and not be read only anymore
- Mobile: Adaptive Performance - Thermal Mitigation Logic changes in GameSDK 3.2 and it was updated in SetFreqLevels() to react to the correct return values
- Physics: Ensured that multi-threaded 2D physics solver handles contact response the same as the non-multi-threaded one. Fix bug where contact masses were different
- Physics: Fixed an issue where a Cloth components external acceleration would be applied in local space instead of world space
- Physics: Fixed an issue where a Cloth components penetration constraint's would be influenced by the Transforms scale, resulting in incorrect behavior
- Physics: Fixed an issue where adding Colliders via the inspector to a Cloth component would not register when done in Play Mode
- Physics: Fixed an issue where providing a null mesh to a previously authored Cloth component, would not clear the constraints causing the inspector to throw
- Physics: Fixed Cloth components Reset functionality to properly reset all data, including colliders, virtual particle weights and self-inter collision indices
- Prefabs: Fixed crash when opening scene with broken prefabs
- Profiler: Optimized frame stats calculation when selecting a sample in Profiler Window
- UI: Fixed the issue where the vertices were not stripped for rich text in multi line
- Universal Windows Platform: Fixed TouchScreenKeyboard not setting Text on HoloLens2
- Windows: Fixed HID devices for NewInput failing to initialize in x86 builds
- XR: Fixed for crash when passing empty string to TryGetFeatureValue
- XR: Fixed Input System always executing XR buttons in LateUpdate

Changes:
Mobile: Adaptive Performance:
- Automatic Performance Control does not lower CPU lower than 1 on GameSDK 3.2 workaround
- Automatic Performance Mode: gpuFactor increased from 0.72 to 0.92 to increase effeciency
- Automatic Performance Mode: gpuUtilizationThreshold increased from 0.7 to 0.9 to increase effeciency
- Automatic Performance Mode: Increase GPU Active time Ratio
- Changed Documentation to make clear that changing CPU and GPU levels is risky and the Automatic Performance Mode should be used instead
- Exchanged GameSDK wrapper with updated version removing GameSDK 3.1 support
- Upgraded to Subsystem Registry 1.1.0 which bumps min version of Adaptive Performance to 2019.4
- XR: Updated Windows Mixed Reality verified package to version 3.3.1

Improvements:
- iOS: Improved dynamic resolution performance for iOS 13, macOS 15 and tvOS 13

System Requirements:
- For development
- OS: Windows 7 SP1+, 8, 10, 64-bit versions only; macOS 10.12+. (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 10.12.6 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 10.12+, Ubuntu 16.04+
- Graphics card with DX10 (shader model 4.0) capabilities.
- CPU: SSE2 instruction set support

- iOS player requires iOS 10.0 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
