   This also applies to headers returned by callbacks.
 * Fixed ``urlencoded_params_matcher`` rejecting matching form data supplied
   as bytes or a binary file-like object.
+* Fixed ``urlencoded_params_matcher`` keeping only the last value of a key
+  that is sent more than once. Repeated keys are now matched against a list,
+  e.g. ``{"id": ["1", "2"]}``.
 * Added ``responses.CallbackRequest`` so callback and matcher annotations can
   include the ``params`` and ``req_kwargs`` attributes added by ``responses``.
