# Django REST framework 3.13
|
|
|
|
## Django 4.0 support
|
|
|
|
The latest release now fully supports Django 4.0.
|
|
|
|
Our requirements are now:
|
|
|
|
* Python 3.6+
|
|
* Django 4.0, 3.2, 3.1, 2.2 (LTS)
|
|
|
|
## Fields arguments are now keyword-only
|
|
|
|
When instantiating fields on serializers, you should always use keyword arguments,
|
|
such as `serializers.CharField(max_length=200)`. This has always been the case,
|
|
and all the examples that we have in the documentation use keyword arguments,
|
|
rather than positional arguments.
|
|
|
|
From REST framework 3.13 onwards, this is now *explicitly enforced*.
|
|
|
|
The most feasible cases where users might be accidentally omitting the keyword arguments
|
|
are likely in the composite fields, `ListField` and `DictField`. For instance...
|
|
|
|
```python
|
|
aliases = serializers.ListField(serializers.CharField())
|
|
```
|
|
|
|
They must now use the more explicit keyword argument style...
|
|
|
|
```python
|
|
aliases = serializers.ListField(child=serializers.CharField())
|
|
```
|
|
|
|
This change has been made because using positional arguments here *does not* result in the expected behaviour.
