- IL2CPP: Improved the error message that was displayed when building for Windows and the required Visual Studio components were not installed.
- IL2CPP: On Android, the public symbol file (for ex., libil2cpp.sym.so) will no longer contain debugging symbols, it will only contain the symbol table. Debugging symbols are present in libil2cpp.dbg.so. This should significantly lower the file size of libil2cpp.sym.so.

- Scripting: Added support for new managed code stripping annotation attributes.
- Scripting: Added support for Unity Version Defines in Assembly definition import options.
- This feature improvement allows scripts to easily specify different code snippets for different Unity version ranges. This is especially useful for introducing calls to newly added public APIs, in which case these API calls need to be guarded by defines based on a Unity version range of a given Unity version or later.
- The Unity version range expression syntax is the same as the package version range expressions. The Unity version format differs from the package version format, so Unity version expressions are evaluated based on some rules specific to the Unity version format:

Comparison of release types follows the following rules:
- So for example, an alpha version is always smaller (earlier) than a beta version, regardless of the Incremental version.
- The Unity versions are allowed to have suffixes (e.g 2020.1.3-bonfire) which are ignored by the Unity version comparison code
- Chinese releases are equivalent to public releases (f) so for the sake of comparison in the version range expression 2020.1f3 would be equal to 2020.1c3.
- Experimental releases don't include an Incremental Version. For example. everything after 2020.2.1x would be treated as a suffix and ignored by the version comparison.
- Scripting: Changed Roslyn analyzers to be run as part of the normal compilation step.
- This also results in analyzer errors being treated as compiler errors.
- Scripting: Greatly improved the performance of GameObject.FindGameObjectWithTag and GameObject.FindGameObjectsWithTag.

- Scripting: Scripting: Improved documentation for Application.isPlaying.
- Scripting: The errors that trigger a script updater are no longer displayed in the console window.
- Scripting: The MenuItem for manually running script updater is removed. It now always offers to update when it finds a compilation error it can fix.

- Search: Improved the search help text when there is no result for the current search tab.
- Shaders: #pragma require now works from compute shaders as well.
- Shaders: Added shader name to messages in the log about shader state being unsupported,.
- Shaders: Shaders can now use UNITY_PLATFORM_<PLATFORM_NAME> defines to specialize compilation per build target platform (examples: UNITY_PLATFORM_OSX, UNITY_PLATFORM_WINDOWS).

Changed:
- 2D: Updated com.unity.2d.sprite package license.
- 2D: Updated com.unity.2d.tilemap package license.
- Android: Removed use of QualitySettings.vSyncCount for Android.
- Android: Vulkan is no longer preferred over OpenGL ES when using Android 7 and for all Mali Midgard GPUs.
- Asset Import: When Meshes have no material defined in the imported file, the ModelImporter now assigns the default material to them rather than creating a 'No name' material sub-asset.
- Burst: Burst enters RC phase.
- Burst: Burst now uses platform-provided memory intrinsics for iOS, tvOS, WASM, and console platforms.
- Burst: Bursted DOTS Runtime Jobs are now decorated with [NativePInvokeCallback] instead of [MonoPInvokeCallback]. This fixes the problem where [MonoPInvokeCallback] jobs could generate callback wrappers which could cause native code to inadvertently interop with the managed VM.
- Burst: Changed how exceptions throw types and messages are stored in our Burst binaries to reduce binary size.
- Burst: Changed the Burst menu-item Safety Checks to a modal choice of Off, On, or Force On. Force On will overwrite any user job or function-pointer with DisableSafetyChecks = true. To avoid users falling into the consistent trap of having Safety Checks set to Off, any reload of the Editor will issue a warning telling the user that Safety Checks have been reset to On.
- Burst: Changed to inliner heuristics to improve build time and reduce executable size.
- Burst: DOTS Runtime shares the logging code path with the general case.
- Burst: Eager-compilation is now cancelled when script compilation starts, to prevent spurious errors related to recompiled assemblies.
- Burst: Exception strings no longer contain the entry-point name of the job/function-pointer that caused the throw. This change was required because the Burst compiler has to produce deterministic results from any given compile, which is fundamentally opposed to per-entry-point function derivations.
- Burst: Improved Burst initialization time.
- Burst: Improved Burst Inspector loading time.
- Burst: Improved eager-compilation performance.
- Burst: Improved performance of "eager-compilation" (scheduling compilation immediately after assemblies are changed) by cancelling queued eager-compilation when entering play mode with Synchronous Compilation unchecked.
- Burst: Improved performance of eager-compilation by not eager-compiling test assemblies.
- Burst: In versions of Unity older than 2019.3, changing the following options in the Burst menu now requires the Editor to be restarted: Enable Compilation, Safety Checks, and Native Debug Mode Compilation. In versions of Unity older than 2019.3, previously-compiled methods were not recompiled after changing those options, which could lead to undefined behavior where methods might not be compiled with the correct options. This change removes that possibility.
- Burst: Made the compiler better at constant-folding complex static readonly constructors.
- Burst: Open-generic static methods are now hidden in the Burst Inspector. They are not supported by Burst, but they were previously visible.
- Burst: Temporarily removed the Burst compiler warning about exception throws not in [Conditional("ENABLE_UNITY_COLLECTIONS_CHECKS")] methods, to let us address user feedback. The next minor version of Burst will reincorporate this in a more friendly manner.
- Burst: The Burst Inspector no longer uses JIT compilation. The code it shows is now compiled the same way as for editor / player usage.
- Burst: The command line option --burst-disable-compilation now entirely disables Burst, including the AppDomain.
- Burst: Updated Cross Compilation Tooling To LLVM 10.
- Burst: Upgraded Burst to use LLVM Version 11.0.1 by default, bringing the latest optimization improvements from the LLVM project.
- Burst: Warnings are hidden in the inspector view.
- Burst: When using "Executable Only" build type on Universal Windows Platform, Burst will now only generate code for a single CPU architecture that you're building for.
- Editor: Deleting an object reference array entry in the Inspector now removes that array element. Previously first deletion set the element reference to none, and the second deletion deleted the element.
- Editor: Deprecated Device Simulator package, feature moved to Core.
- Editor: Quick Search is now part of the Unity Editor and no package needs to be installed.

Topaz Sharpen AI 1.4.0
New Feature:
- Intel Optimization (OpenVino) in.
- Now a new option “Enable Intel OpenVino” is in preferences. If you choose “Yes”, it will optimize Intel CPUs and Intel iGPUs for Sharpen. Typically, it will make Sharpen run 5 times faster than the previous “CPU” mode. But we cannot guarantee if it can work for CPUs from other vendors (e.g., AMD) or any Intel CPUs before 6th generation. If you still have very high performance dedicated GPUs (e.g., NVIDIA 1080), “Enable discrete GPU” (Yes) option will be the best choice. However, if you have relatively better Intel CPUs or Intel iGPUs than low performance GPU, you will see faster performance on Intel optimization (Yes)
- Automatic detection for the best devices choice.
- Now you do not have to choose between GPU/CPU or enable/disable Intel optimization manually. Sharpen will automatically run a benchmark and choose the best preferences settings for you to achieve the highest speed on your computer. The benchmark will only be triggered once when you process the first image. Thus, the first image will take longer time than usual.3.

Change:
- Model update.
- The updated AI is trained with an improved algorithm. For Focus and Stabilize mode, it produces much sharper images than previous versions.
