Several changes were applied to improve security. See ADV-2017-17, ADV-2017-19, ADV-2017-20 and ADV-2017-21 in Security Bulletins for more details.
Publishing a workbook with a custom SQL data source containing certain special characters would fail with an error.
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.
Desktop license reporting would sometimes show duplicate entries with missing product keys.
Subscription emails were not sent if you had the backgrounder.subscription_image_caching setting set to false.
If you added an image to a product description, the formatted URL would be displayed in the description instead of the image.
An invalid JSON error would occur when loading certain dashboards that contained 1 pixel wide objects.
In some cases, complex queries sent from Data Server processes would cause Data Engine processes to consume excessive memory and eventually crash.
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.
In web authoring, clicking to show all values in a date range filter, and then adjusting the slider, would sometimes fail to correctly update the view.
An internal error would sometimes occur when loading views after upgrading to Tableau Server 10.2.3 or 10.3.1 and higher.
Session Ended by Server errors would frequently occur when lazy connections were disabled.
Existing workbooks containing Hive or Impala connections with embedded passwords failed to load after upgrading to Tableau Server 10.2 or higher from a previous version.
When you published a statistical file to Tableau Server as a data source, Name unavailable would be displayed in the Connects To column in the Data Sources view on Tableau Server. Republishing the data source is required to correct the problem.
Workbooks loaded using URL parameters would error or fail to respect the URL parameters if the workbook was set to prompt for data source credentials.
Tabcmd response times would slowly degrade when the tabcmd export command was repeatedly executed.
Workbooks connected to spatial files would fail to load with an unknown server error.
