******************
* Fix 8: we now have date, datetime and duration preferences
* Fix 108: Dropped tests and guaranteed compatibility with django 1.8 and 1.9, though
* Fix 103: bugged filtering of user preferences via REST API
* Fix 78: removed ``create_default_per_instance_preferences``.
This is *not* considered a backward-incompatible change as this method did nothing at all
and was not documented
