+Feature: #83476 - Load merged JS files asynchronous
+===================================================
+
+See :issue:`83476`

+The async attribute is now assigned to the script tag of the concatenated JS files if all files have the async attribute enabled in TypoScript.
+
+Example:
+--------
+
+.. code-block:: typoscript
+
+   config.concatenateJs = 1
+
+   page = PAGE
+   page.includeJSFooter {
+       test = fileadmin/user_upload/test.js
+       test.async = 1
+
+       test2 = fileadmin/user_upload/test2.js
+       test2.async = 1
+   }
