 Pickle file I/O protocol parameter
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-:func:`to_pickle` now allows to specify the protocol used by the Pickler.
-The 'protocol' parameter defaults to HIGHEST_PROTOCOL. For Python 2.x, HIGHEST_PROTOCOL is 2.
-Since Python 3.0 (respectively 3.4), HIGHEST_PROTOCOL is 3 (respectively 4).
-A negative value for the protocol parameter is equivalent to setting its value to HIGHEST_PROTOCOL.
