Hi everyone.

This is just a quick heads up, especially for the folks working on the Django
web ui or other REST API clients for Mailman 3, that I've made a change to the
API.

The IMailingList attribute ``host_name`` has been changed to ``mail_host`` for
consistency.  (LP: #787599)  This change is pushed to the bzr trunk and will
be released with 3.0a8.

Cheers,
-Barry
