* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth.
* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic).
* **GraphQL** integration with <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> and other libraries.

Usaba tipos personalizados en sus declaraciones en lugar de tipos estándar de Python, pero aún así fue un gran avance.

También fue uno de los primeros frameworks en generar un esquema personalizado declarando toda la API en JSON.

```Dockerfile
# ⛔️ No hagas esto
CMD fastapi run app/main.py --port 80
```

Asegúrate de siempre usar la **forma exec** para garantizar que FastAPI pueda cerrarse de manera adecuada y que [los eventos de lifespan](../advanced/events.md){.internal-link target=_blank} sean disparados.

 *  Fix: Don't crash when an interceptor retries when there are no more routes. This was an
    edge-case regression introduced with the events cleanup in 3.14.0.

 *  Fix: Provide actionable advice when the exchange is non-null. Prior to 3.14, OkHttp would
    silently leak connections when an interceptor retries without closing the response body. With
    3.14 we detect this problem but the exception was not helpful.
