--------
This release primarily adds compatibility with django-filter 1.0 (more details
in 144), and is an intermediate step to overhauling the behavior of filters
that span relationships.
As `RelatedFilter` is a subclass of `ModelChoiceFilter`, you may take advantage
of the `callable` behavior for the `queryset` argument. The `queryset` is now a
required argument, which is a forwards-incompatible change. You can provide the
model's default queryset to maintain the current behavior, or a callable, which
will allow you to filter the queryset by the request's properties.
