2020.1.12f1 Release Notes
System Requirements Changes
For running Unity games
- iOS: minimum version incremented to 10.0 (from 9.0).
2D: Fixed dynamic batching for TilemapRenderer in Individual mode with SpriteRenderers when Sprites have secondary textures set. (1277223)
2D: Fixed totalSpriteSurfaceArea to get reserialized when switching build platforms. (1273235)
AI: Fixed an issue where CreateLocation does not return correct projection of an input point on an OffMeshLink. (1246726)
Android: Fixed to enable Unity perform Android SDK update with elevated privileges on Windows. Previously if Android SDK/NDK would be installed in folder like Program Files, Unity wouldn't be able to update Android SDK. With new behavior user will be prompted with a dialog where Unity will ask - if it can run sdkmanager.bat with elevated privileges. (1281951)
Asset Import: Fixed such that substance files do not display an import warning anymore when the substance plugin is correctly set up in a new project. (1221240)
Audio: Fixed to synchronize audio source playing state with timeline clip playing state. (1146694)
Audio: Fixed to unblock streaming mp3 on supported platforms. (1224487)
Editor: Fixed -api-profile flag causing editor to write to ProjectSettings/ProjectSettings.asset using binary serialization mode despite ForceText being configured in ProjectSettings/EditorSettings.asset.
Editor: Fixed a crash that could occur when Burst compilation was scheduled before Burst had been initialized.
Editor: Fixed incorrect error message in audio importer. (1279810)
Editor: Fixed incorrect key values being passed to the new input system on Linux. (1275964)
Editor: Fixed to unblock streaming mp3 when targeting webgl. (1252868)
GI: Fixed an error log message in the light conversion script that could occur when light colors produced denormalized floats. Light without any color channel exceeding 1e-20 will be treated as completely black (0,0,0). (1275179)
GI: Fixed an issue where Enlighten would run on build despite being disabled. (1258154)
Graphics: Fixed an issue where in some cases, Custom Render Textures would not be rendered (generally with asset bundles or in a standalone build). (1281400)
Package Manager: FIxed the Assets > Properties window to display a selected package's display name instead of the id in the title tab. (1217758)
Package Manager: Fixed the crash due to a corrupted ProjectCache.bin that could occur when opening a project last opened in a different Unity Editor version. (1276565)
Package Manager: Fixed VW being unable to see Unity packages since they access them from a server that is not on unity.com domain. (1274555)
Particles: Fixed missing Trail Material slot in the Inspector. (1284719)
Prefabs: Fixed crashes caused by broken scenes, where missing prefabs have been serialized badly into the scene file. (1280054)
Prefabs: Fixed editor crashes caused by prefabs instance with missing assets. (1219109)
Prefabs: Fixed Editor crashes/hangs when using PrefabUtillity.SetPropertyModifications() where some propertymodification.target are invalid (null). (1276769)
Prefabs: Fixed such that managed field types in prefabs containing Arrays are now serialized correctly to allow field to be initialized before Array.size is set. (1255012)
Profiler: Fixed such that the UI System Preview Window in the UI Profiler module now has its title set correctly. (1238881)
Serialization: Fixed to make sure that when objects are created as part of a deserialization process the class default initializers are called. (1253433)
Services: Added a fix for the removal of CEF from the editor causing an exception when a tracker is added to a game object.
The removal of CEF meant that when analytics is not enabled, and you add an analytics tracker to a game object, the library
required to create the "go to service menu and enable analytics" button didn't exist, and thus would throw an exception. The solution was
to have a seperate class initialised on load that would override this functionality for all editors that don't have this library. (1277664)
Universal Windows Platform: Fixed a crash which happens when rapidly switching between input fields with text in them. (1278859)
Universal Windows Platform: Fixed excessive memory usage when application gets suspended. (1279629)
Universal Windows Platform: Fixed Y coordinate on new input system when running on non-100% scaled display. (1278638)
Version Control: Fixed an issue where duplicate keys could cause empty data to be output, and improved transform mapping to work with a wider range of Unity versions. (1258865)
Video: Fixed to use 2d spatial blending when playing audio in direct mode. (1276611)
- Package Manager: Fixed such that the Package Manager no longer discards the existing package state in case of critical errors such as failure to parse the project manifest.
