+Version 0.2:
 
 * ``MANDRILL_API_URL`` is no longer required in settings.py
 * Earlier versions of Djrill required use of a ``DjrillMessage`` class to
   specify Mandrill-specific options. This is no longer needed -- Mandrill
   options can now be set directly on a Django ``EmailMessage`` object or any
   subclass. (Existing code can continue to use ``DjrillMessage``.)
