 - Removed ``setuptools`` from the ``requires`` list in ``setup.py`` because
   it caused installation issues on some systems.
 
+- The ``main()`` function of the ``supervisord`` module now allows an
+  ``options`` instance to be passed in.  This is consistent with the
+  ``main()`` function of ``supervisorctl``, which already allowed this.
