 ### Unable to run dashboard extension using self-signed certificates
 
-Tableau uses Qt WebEngine to embed browser pages within a dashboard. Tableau now uses Qt WebEngine 5.15, which is based on Chromium version 87.0.4280, with additional security fixes from newer versions of Chromium. Because Tableau is now using Qt WebEngine (5.15), dashboard extensions running with self-signed certificates (SSL) might not work in Tableau 2021.1, or in the most recent Tableau maintenance releases: 2020.2.7+, 2020.3.6+, and 2020.4.2+.
