 Release Notes
 -------------
 
+Version 0.3.0:
+
+* Attachments are now supported
+* Mandrill templates are now supported
+* A bcc address is now passed to Mandrill as bcc, rather than being lumped in
+  with the "to" recipients. Multiple bcc recipients will now raise an exception,
+  as Mandrill only allows one.
+* Python 3 support (with Django 1.5)
+* Exceptions should be more useful: ``djrill.NotSupportedByMandrillError``
+  replaces generic ValueError; ``djrill.MandrillAPIError`` replaces
+  DjrillBackendHTTPError, and is now derived from requests.HTTPError. (New
+  exceptions are backwards compatible with old ones for existing code.)
+
 Version 0.2.0:
 
 * ``MANDRILL_API_URL`` is no longer required in settings.py
