• Android: Users can include custom asset packs into the build, by adding assets to the directory ending with '.androidpack'. This requires custom Gradle version 6.1.1 or higher.

• Android: When building Android App Bundle with Split App Binary enabled, Unity will create asset packs. This requires custom Gradle version 6.1.1 or higher.

• Stadia: Added support for Orbit Profiler

• Version Control: - Plastic: Added support for inviting other members. This option is available from the gear / settings icon.

  • Plastic: Added support for signing in with Cloud Edition. This is available during the onboarding screen if you have never signed in.

  • Plastic: Added support for turning off Plastic in their project. This option removes the Plastic metadata from your directory. This option is available under Assets > Plastic SCM > Turn off Plastic SCM

  • Plastic: Added notification on the Plastic SCM tab title to indicate incoming changes. Users will no longer need to have the Plastic SCM window visible to know there are incoming changes.

  • Plastic: Auto configuration of SSO

  • Plastic: Added date column in incoming changes

Improvements

• Graphics: Improvements to scene culling CPU performance - Shadow casters are rejected earlier if their shadow casting is disabled which should improve performance in scenes with scenes with lots of renderable objects that are set to not cast shadows. (1322874)

• Graphics: Running out of memory with Vulkan backend is now clearly told in Editor.log

• Graphics: Update Postprocessing v2 package to 3.1.1

• Graphics: Upgrade to Intel Open Image Denoise 1.1.0. Significantly improves denoising quality and reduces ringing. (1260772)

• iOS: Ignore plugins with wrong CPU type when creating xcode project, e.g. when building for run on device, libraries having CPU type "x64" (i.e. simulator libraries) will be ignored

• Profiler: Added missing memory labels sizes to the memory snapshot format, in order to give real value to the prexisting label list. Api for access this data will be found inside the memory profiler package

• Profiler: Added profiler memory stats data, data is similar to the Profiler Module data found in the Profiler Window

• Profiler: Added profiler target data to memory snapshot format, data consists of elements such as unity version, product name, total gfx memory, total physical memory etc.

• Profiler: Encoded managed heap section type inside the snapshot format, for retrieval via the memory profiler package

• Profiler: Reworked native connection reporting for the memory profiler in order to properly report connections between assets

• Version Control: - Stability and performance improvements

API Changes

• Android: Added: New APIs to manage fast-follow and on-demand delivered asset packs. The APIs wrap Google's PlayCore functionality.

• iOS: Added: Function PBXProject.GetEntitlementFilePathForTarget().

• Services: Changed: On some platforms we strip out the Analytics modules completely. so any user code that references anything from Analytics will not compile on these platforms. this PR is to update the documentation informing users of the need to #ifdef this code out for this situation (1333730)

Changes

• Android: Allow Android Player to use Vulkan on GPUs that are currently unknown to Unity on Android 11 or newer.

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
