This minor release includes the following changes:
Git version control authentication issue resolved
In the initial release of Android Studio 3.6, operations requiring authentication in Git version control were broken in the IDE. This bug has been fixed in 3.6.1. See Issue #124680708 for more information.
Multi Preview feature removed
This feature wasn't quite ready for version 3.6 of Android Studio and had been inadvertently left in the final release. We've removed Multi Preview from Android Studio 3.6.1. However, if you would like to use Multi Preview, a more refined version of the feature is available in the 4.0 beta releases.
For information on new features and changes in all releases of Android Studio, see the Android Studio release notes.
