Because of the change, users and developers of some WDCs might encounter issues. For more information, see Troubleshoot WDC WebEngine Issues in Tableau 2019.4 and later.
In addition, the debugging process for WDCs has changed. Developers will now be able to use the Chrome DevTools for debugging. For more information, see the Debugging a WDC in Tableau Desktop 2019.4 (and later).
If you are curious to see what new features are available with the new Chromium-based browser in Tableau 2019.4, you can open the Web Data Connector dialog box in Tableau, and point to the HTML5 test site (
https://html5test.com). Note that this test site is not a WDC. The HTML5Test is a web site that reports the browser’s compatibility with the HTML5 standards.
