New features, enhancements, and other improvements

  • The Help Desk enrollment email setting is also configurable via the Duo Admin Panel.

Bug fixes

  • Fixed an issue where editing a user with a pending enrollment could result in orphaned enrollment records on the Pending Enrollments page of the Admin Panel. Now, pending enrollments will always show the current username and email address for the associated user.
  • Fixed an issue where email addresses with non-ASCII characters were not being displayed correctly on the Pending Enrollments page of the Admin Panel, in the Admin Actions report, and during administrator login or provisioning.
  • Fixed an issue where browser versions with alphanumeric characters in the version number (example: Firefox 90.0a1) caused an error on the Endpoints page in the Admin Panel.
  • Fixed an issue where the “Allow admins with Help Desk role to send enrollment emails” option on the Settings page in the Admin Panel appeared editable even for accounts without role-based administrators (e.g. Duo Free).
