+Deprecation: #104154 - Deprecate Utility.updateQueryStringParameter()
+=====================================================================
+
+See :issue:`104154`
+
+Description
+===========
+
+The :js:`Utility.updateQueryStringParameter()` method in the
+:js:`@typo3/backend/utility.js` module was introduced in TYPO3 v8 as a bugfix
+for highlighting in the old ExtJS-based page tree. Since removal of ExtJS in
+TYPO3 v9 the method has been unused.
+
+Because safe removal of the method cannot be guaranteed as this point, it is
+therefore deprecated.
+
+
+Impact
+======
+
+Calling :js:`Utility.updateQueryStringParameter()` will result in a JavaScript
+warning.
+
+
+Affected installations
+======================
+
+All 3rd party extensions using the deprecated method.
+
+
+Migration
+=========
+
+Now, JavaScript supports the :js:`URL` and its related :js:`URLSearchParams`
+object that can be used to achieve the same result:
+
+..  code-block:: javascript
+
+    const url = new URL('http://localhost?baz=baz');
+    url.searchParams.set('baz', 'bencer');
+    const urlString = url.toString(); // http://localhost?baz=bencer
