* There's a new *path operation decorator* parameter `response_model_skip_defaults`.
        * The name of the parameter will most probably change in a future version to `response_skip_defaults`, `model_skip_defaults` or something similar.
    * New [documentation section about using `response_model_skip_defaults`](https://fastapi.tiangolo.com/tutorial/response-model/#response-model-encoding-parameters).
