 * New configuration variable, ``mock_use_standalone_module`` (defaults to ``False``). This forces

-  and use a newer version than the one available in the Python distribution.
+  a newer version than the one available in the Python distribution.
 
 * Previously the plugin would first try to import ``mock`` and fallback to ``unittest.mock``
   in case of an ``ImportError``, but this behavior has been removed because it could hide
