Sierra was upgraded to the latest release (4.1) on November 7, 2018. This upgrade includes all new features, updates, and fixes included in both Sierra 4.0 and 4.1. I encourage all Sierra users to review the New Features portion of the Release Notes for both 4.0 and 4.1. Links can be found on the Sierra SharePoint
Please note that Sierra 4.1 requires that all Sierra passwords have an 8 character minimum. This is enforced immediately for new accounts and upon password change for previously existing accounts.
We did experience a few post-upgrade issues. At this time all but one have been resolved. You can view the list of post-upgrade issues on the Sierra Share Point.
Please submit a Footprints ticket for all Sierra requests, problem reports, or questions.
