2020.3.8f1 Release Notes
- Asset Pipeline: Improved performance of flushing the preload operation queue from the main thread. This can occur when accessing an operation's result on the main thread before it is completed. (1322086)
- Editor: Added: EditorUtility SetDefaultParentObject and ClearDefaultParentObject methods were added.
- Graphics: Update SRP packages to 10.5.0. See the package change log for additional information.
2D: Fixed crash when viewing Sprite Atlas. Disabled code that could potentially cause high memory use and unnecessary object loads at certain conditions. (1330345)
Asset Import: Fixed an issue where materials were not allowed to be extracted into packages. (1282867)
