## 0.31.0

* Upgrade Pydantic supported version to `0.29.0`.
    * New supported version range is `"pydantic >=0.28,<=0.29.0"`.
    * This adds support for Pydantic [Generic Models](https://docs.pydantic.dev/latest/#generic-models), kudos to [@dmontagu](https://github.com/dmontagu).
    * PR [#344](https://github.com/tiangolo/fastapi/pull/344).

También hay docenas de alternativas, todas basadas en OpenAPI. Podrías añadir fácilmente cualquiera de esas alternativas a tu aplicación construida con **FastAPI**.

También podrías usarlo para generar código automáticamente, para los clientes que se comunican con tu API. Por ejemplo, frontend, móvil o aplicaciones de IoT.
