2021.2.13f1 Release Notes


  • Scripting: Improved AssemblyUpdater to not try to connect to VCS unless there assemblies under VCS that needs updating. (1353761)

  • Scripting: Improved invalid ApiUpdater configs detection.

  • UI Toolkit: Refactored UI Builder's asset modification processor's OnWillSaveAssets() callback to save changes automatically on the Save and Save Project global commands.

  • UI Toolkit: Save operation is properly skipped on the Duplicate command which, unfortunately, also uses the (same) asset modification processor callback.
