2019.4.23f1 Release Notes

Features

• Graphics: Added support for importing 16bit per channel integer formats without quantization. This also exposed new TextureFormats R16G16, R16G16B16 & R16G16B16A16.

Improvements

• Graphics: Improved the application of outstanding pending changes to RendererScene after a camera render.

• 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 needs to be guarded by defines based on a Unity version range of a given Unity version or later.
  Unity version range expression syntax is the same as package version range expressions. Unity version format differs from package version format, thus Unity version expressions are evaluated based on some rules specific to the Unity version format:
  

  • Comparison of release types follows the following rules: a<b<f=c<p<x. So e.g. 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-acme) 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 - e.g. everything after 2020.2.1x would be treated as suffix and ignored by the version comparison.

API Changes

• Graphics: Added: Added new SystemInfo.supportsStoreAndResolveAction API to check for StoreAndResolveAction store action support on a specific platform.

Changes

• Graphics: Updated postprocessing package to 3.0.3.

• Graphics: Updated postprocessing package to 3.1.0.

2019.4.15f1 Release Notes

Fixes

• AI: Correct the stray NavMeshAgent to always move to the closest NavMesh instead of somewhere above or below. (1072945)

With new behavior user will be prompted with a dialog where Unity will ask - if it can run sdkmanager.bat with elevated privileges. (1281951)

• Android: Fixed Switch internal Unity allocator to DynamicHeapAllocator which is compatible with Scudo allocator introduced in Android 11.

• Graphics: Fixed VertexCompression setting being interpreted incorrectly. (1281361)

• Graphics: Updated Post-processing package to version 3.0.1.

• IL2CPP: Corrected the behavior of UnityEngine.Mathf methods when invoked via a delegate for WebGL players. (1252289)

• IL2CPP: Fixed to correctly report the public key for assemblies where is exist. (1271060)

• IL2CPP: Fixed to enforce the --maximum-recursive-generic-depth command line option at run time. (1276405)

• IL2CPP: Fixed to provide a user-readable error during code conversion for value types which have a recursively defined field that is a nullable version of the same type. (1268007)

• IL2CPP: Fixed un-needed box call in generic code when using enums. (1271254)

• Package Manager: The Packager Manager no longer fails to write the project manifest file (Packages/manifest.json) or the lock file (Packages/packages-lock.json) when they are read-only. (1263361)

• Physics: Ensure that changing a Rigidbody2D constraint on a prefab instance results in the change being indicated by a bold label in the inspector. (1265836)

• Physics: Ensure that changing the Rigidbody2D mass distribution correctly adjusts the center of mass velocity. (1272075)

• Physics: Fix an issue when filtering out bad 2D physics collision shapes produced by the internal shape tessellator where occasionally a good shape is filtered out. (1274172)

• Physics: Fix an occasional crash when destroying a PhysicsScene2D while destroying active contacts or collider-ignore-collision settings. (1268659)

• Profiler: Fixed an issue where FrameCount inside the ProfilerUserSettings would clamp to a 0 - 2000 frame range instead of 300 - 2000, thus causing the charts inside the ProfilerWindow to throw out of range exceptions. (1288878)

• Profiler: Fixed issue where entering PlayMode with the editor open would throw "GetInt is not allowed error". (1289794)

• Scripting: Fixed issue where thread statics that reused thread static slots would not adhere to type alignment. This would cause the garbage collector to incorrectly clean up thread static data because it would only scan pointer aligned memory for references. This would lead to memory becoming corrupted and inducing random crashes. (1266322)

• UI: Canvas RectTransform size calculation now done for standalone renders as well. Camera needs to be enabled to pick up the RenderTexture size change. (833456)

• UI Toolkit: Added EditorWindow.CreateGUI entry point to safely add visual elements to the window. (1281376)

• XR: Correct mismatched Vulkan framebuffer and renderpass configurations that caused validation errors, and issues with rendering when using multiple rendering passes.

• XR: Fixed an issue where the XR splash screen is missing when using SRP. (1230976)

• XR: Fixed Hololens 2 apps pausing when carry along apps are open.

• XR: Fixed issue where attempting to use separate cameras while using stereo multipass to render each eye caused the left eye to render the right eye and the right eye to not render at all. (1280266)

• XR: Fixed stereo skybox rendering when a sphere is used instead of a cube. (1223567)

API Changes

• Physics: Added: Added writeable WheelCollider.sprungMass, to enable explicit mass distributions. In addition to that, expose WheelCollider.ResetSprungMasses() to reset the vehicle back to automatically calculated implicit sprung masses. It's the same usage pattern as with Rigidbody.inertiaTensor / Rigidbody.ResetInertiaTensor().

Changes

• Package Manager: 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.

Improvements

• IL2CPP: Improved error message when required Visual Studio components are not installed when building for Windows.
