-------------------
* Dropped support for Django 1.7 (support expired on December 1 2015,
see https://www.djangoproject.com/download/supported-versions).
* Require `setuptools>=18.5` at install time due to use of
`python_platform_implementation` environment marker.
* Moved repository to https://github.com/django-ddp/django-ddp (new
Github organisation).
* Started work on documentation refresh.
* Fail on start if any child threads can't start (eg: port in use).
* Rudimentary support for dynamic publications which may now refer to `this.user`.
* Correctly close DB connections during shutdown, useful for test suite.
* Add missing versions and dates to the change log, and note on Semantic
Versioning.
* Emit `django.core.signals.request_finished` to close DB connection and
yield to other greenlets between processing messages from WebSocket.
* Back to universal wheels, thanks to PEP-0496 environment markers.
* Expand test suite coverage to start a DDP server instance and perform
a HTTP GET request, no WebSocket/DDP tests yet. Fails in Pyton 3
because of a bug in `gevent-websocket`
(https://bitbucket.org/noppo/gevent-websocket/issues/54/python-3-support).
* Fix for 23 (Python 3 compatibility).
* Set `application_name` on PostgreSQL async connection.
* Send `django.core.signals.request_finished` when closing WebSocket.
* Don't require `DJANGO_SETTINGS_MODULE` to import API.
* Tox test suite updated to runs against Python 2.7/3.3/3.4/3.5 and
Django 1.8/1.9.
* Build wheels from tox environment to ensure consistency.
* Remove `debug` argment from `PostgresGreenlet` class (unused).
