SAML authentication from Tableau Desktop to Tableau Server would fail in some environments.
With recent updates to the Amazon Redshift driver, connections could fail with a no pg_hba.conf entry for host error. A workaround was to republish workbooks or data sources with Require SSL checked in the data connection.
Extracts would unexpectedly refresh when you switched between the Data Source tab and a sheet tab.
When source and target sheets were based on different data sources, filter actions failed to trigger sheet navigation when the action was set up to use selected fields.
An internal error would occur, in some cases, when you attempted to sort a calculated field containing conditional statements.
When you were connected to Snowflake and cast a string dimension to an integer or float, a Numeric value is not recognized error would occur.
Query execution errors would occur when you connected to Cloudera Impala using custom SQL with a date parameter.
In certain cases involving parameter-based calculated fields used as filters, incorrect or inefficient SQL queries would be generated when connected to Google BigQuery, Apache Drill, or Amazon Redshift, resulting in error or poor performance.
In some cases, when you joined multiple tables and performed a pivot, null values would incorrectly appear in Pivot Field Names.
An internal error would occur when you renamed a sheet and then tried to use the controls on the Pages shelf in the sheet.
Printing to PDF was noticeably slower in Tableau Desktop 10.0 and higher compared to prior versions.

In some cases, aggregated calculated fields would return no data after an extract was created.
