NNTP Objects
------------
-:class:`NNTP` instances have the following methods. The *response* that is
-returned as the first item in the return tuple of almost all methods is the
-server's response: a string beginning with a three-digit code. If the server's
-response indicates an error, the method raises one of the above exceptions.
+When connected, :class:`NNTP` objects support the following methods and
+attributes.
-.. note::
- Many of the following methods take an optional keyword-only argument *file*.
- When the *file* argument is supplied, it must be either a :term:`file object`
- opened for binary writing, or the name of an on-disk file to be written to.
- The method will then write any data returned by the server (except for the
- response line and the terminating dot) to the file; any list of lines,
- tuples or objects that the method normally returns will be empty.
+Attributes
+^^^^^^^^^^
+.. attribute:: NNTP.nntp_version
+
+ An integer representing the version of the NNTP protocol supported by the
+ server. In practice, this should be ``2`` for servers advertising
+ :rfc:`3977` compliance and ``1`` for others.
+
+ .. versionadded:: 3.2
+
+.. attribute:: NNTP.nntp_implementation
+
+ A string describing the software name and version of the NNTP server,
+ or :const:`None` if not advertised by the server.
