 - New back/forward indicator in the statusbar
 - New `bindings.key_mappings` setting to map keys to other keys
-- New `qt_args` setting to pass additional arguments to Qt/Chromium
+- New `qt.args` setting to pass additional arguments to Qt/Chromium
 - New `backend` setting to select the backend to use (auto/webengine/webkit).
   Together with the previous setting, this should make wrapper scripts
   unnecessary.
