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.

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"
When you added a worker with backup Data Engine and Repository processes, scheduled extract refreshes would sometimes fail until the File Store on the worker finished synchronizing.
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.
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.
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.
Running filter actions could sometimes be significantly slower when compared to prior versions.
Importing a Tableau Server 9.3 site into Tableau Server 10.1, using the tabadmin importsite command, would fail with an error.
Type-in parameter font formatting did not match what was specified in Tableau Desktop when viewed in a browser and could sometimes result in white text on a white background.
Using web authoring to edit a workbook containing a global filter would result in an internal error and prevent editing of the workbook.
Copying data from Tableau Desktop or exporting data from Tableau Server could multiply some decimal values by a factor of ten billion in the resulting data.
It was not possible to add a tenth worker node (i.e. 1 primary + 10 workers) when configuring Tableau Server.
