After upgrading to Tableau Server 10.0 or higher, from an older version, workbook load times were consistently slower in some cases.
In published workbooks containing sheets and dashboards shown as tabs, changing parameter selections sometimes did not update the parameter control, to reflect the new selection, when switching between tabs. The actual visualizations, however, were always correctly updated based on the parameter selection.
Specifying a negative value for number of decimals in the ROUND() function would cause Tableau Desktop and Tableau Server VizQL processes to error and crash.
Scheduled extract refreshes for workbooks containing extracts and at least one published, SSO-authenticated or user-delegated, live data source would fail with an error: "Cannot evaluate user filter; no current user or group"
In workbooks connected to an SAP BW data source, dimension member aliases would sometimes become mixed up when the workbook was loaded in Tableau Server.
Scheduled extract refreshes for workbooks containing both extracted SAP HANA connections and live, SSO-authenticated SAP HANA connections would fail.
URL actions in the Traffic to Views and Traffic to Data Sources administrative views did not handle sites correctly, resulting in "That page could not be accessed." errors.
Vizqlserver processes would intermittently crash when loading certain workbooks if the vizqlserver.querylimit setting value was exceeded.
Queries generated by published Exasol data sources could sometimes be significantly less efficient than those generated when using an equivalent live connection in Tableau Desktop.
