In environments with mixed SAML and non-SAML sites, you could not add a site-SAML user to a SAML site if you had first signed into a non-SAML site and then switched to the SAML site.

It was not possible to synchronize groups from a secondary domain using the Tableau Server web UI. The same operation was successful using tabcmd.
Publishing a Web Data Connector (WDC) data source or a workbook containing a WDC to Tableau Server could cause the Data Sources list to display no content if the WDC URL contained a space.
Dashboards with device layouts set to fit width did not update to fit when devices were rotated.
When viewing workbooks in a thumbnail view on Tableau Server, the star icon to toggle a favorite would not be displayed for workbooks with long names that wrapped to a second line.
