Question
Beginning with 2021.4, Tableau is moving from a 30-month support policy to a 24-month support policy for all products. All new versions will have 24-months of support provided by our Support organization including the availability of maintenance releases. For currently supported software versions 2020.4.x - 2021.3.x, our Support organization will continue to provide the original 30 months of support assistance to customers*, with maintenance releases available for 24 months from the original release date for each version.*As of February, 2023 the Support Services page has been updated to reflect our new Technical Support policy. All versions of Tableau Desktop and Tableau Server, including 2020.4.x-2021.3.x, will receive 24 months of maintenance and full support, followed by a 12-month window of limited support including only documentation clarification and limited assistance in troubleshooting issues encountered when upgrading to the latest version of the product. The 6 months of additional support originally provided to those earlier releases will no longer be available. This change ensures that our Support windows match appropriately with the development cycles available to support them.
