+*********
+
+*Release date: Mar 05, 2018*

+
+*********
+**1.4.4**
+*********
+
+*Release date: Feb 26, 2018*

+- **IMPROVED:** ``type`` for ``ChoiceField`` generated by a ``ModelSerializer`` from a model field with ``choices=...``

+
+- **FIXED:** the ``coerce_to_string`` is now respected when setting the type, default value and min/max values of

    This means that you should generally avoid view or method-specific ``FieldInspector``\ s if you are dealing with
    references (a.k.a named models), because you can never know which view will be the first to generate the schema
    for a given serializer.
+
+   **IMPORTANT:** nested fields on ``ModelSerializer``\ s that are generated from model ``ForeignKeys`` will always be
+   output by value. If you want the by-reference behaviour you have to explictly set the serializer class of nested
+   fields instead of letting ``ModelSerializer`` generate one automatically; for example:
+
+   .. code-block:: python
+
+      class OneSerializer(serializers.ModelSerializer):
+         class Meta:
+            model = SomeModel

+
+         class Meta:
+            model = SomeParentModel
+            fields = ('id', 'child')
+
+   Another caveat that stems from this is that any serializer named "``NestedSerializer``" will be forced inline
+   unless it has a ``ref_name`` set explicitly.
