 While you are debugging your extension, there are times you might want to reload or refresh your web page to execute and debug different parts of your code. However, when you click **Reload** from the shortcut menu to reload your extension, the remote debugger loses the connection with the extension. The reason for this is that **Reload** option tears down and re-creates the browser control, which means you'll need to establish a new debugging session.

+### Tableau Extensions API version 1.15.0
+
+*September 2025*
+
+* Tableau Dashboard Extensions API library: `tableau.extensions.1.15.0.js` <br />(download or clone the Extensions API repository on [GitHub](https://github.com/tableau/extensions-api)). <br />
+
+* Certain features in this release are only available in Tableau Cloud and Tableau Desktop 2025.3 or later. Download [Tableau Desktop](https://www.tableau.com/support/releases).
+
+What's new in this release:
+
+* Added `Cloud`, `PublicWeb`, and `PublicDesktop` as `Environment.context` values (`ExtensionContext`). The value indicates in which context the extension is currently running.
+
+* Added `sendDialogMessageAsync` method and `DialogMessageReceived` event to the UI namespace.
+
+* The `closeDialog` method can now be called from the extension frame to forcefully close the dialog.
+
+* If you use Tableau Desktop for debugging your extension, there is a new command line argument you need to include when you launch Tableau in debug mode. You need to add `--webEngineArgs` in front of the remote debugging port option. For example, on Windows the command would look something like the following:
+
+```cli
+"C:\Program Files\Tableau\Tableau <version>\bin\tableau.exe" --webEngineArgs --remote-debugging-port=8696
+```
