This new release introduces backward incompatible changes:
native_data type is now private, you have to use the new data_* and to_ocaml_* functions to convert the data between OCaml world and MySQL world.get_result_set function has a new signature: val get_result_set : result -> Mp_result_set_packet.result_selectinsert_id is now a tuple of type (Int64.t * Big_int.big_int). The Int64 value must be used when the auto_increment field is not a BIGINT UNSIGNED, otherwise the Big_int value must be used.
