+* Added :func:`~logging.getLevelNamesMapping`
+  to return a mapping from logging level names (e.g. ``'CRITICAL'``)
+  to the values of their corresponding :ref:`levels` (e.g. ``50``, by default).

+* Added a :meth:`~logging.handlers.SysLogHandler.createSocket` method
+  to :class:`~logging.handlers.SysLogHandler`, to match
+  :meth:`SocketHandler.createSocket()
+  <logging.handlers.SocketHandler.createSocket>`.
+  It is called automatically during handler initialization
+  and when emitting an event, if there is no active socket.
