* this structure is never mutated, it provides a thread-safe view of the backing map.

!!! tip "Tipp"
    Der „PATCH“ ist die letzte Zahl, zum Beispiel ist in `0.2.3` die PATCH-Version `3`.

Sie sollten also in der Lage sein, eine Version wie folgt anzupinnen:

```txt
fastapi>=0.45.0,<0.46.0
```

Nicht abwärtskompatible Änderungen und neue Funktionen werden in „MINOR“-Versionen hinzugefügt.

Pero aún así, la experiencia final no es la mejor 😞.

Esta sería la historia paralela equivalente de las hamburguesas 🍔.

Para un ejemplo más "real" de ésto, imagina un banco.

Hasta hace poco, la mayoría de los bancos tenían varios cajeros 👨‍💼👨‍💼👨‍💼👨‍💼 y una gran línea 🕙🕙🕙🕙🕙🕙🕙🕙.

Todos los cajeros haciendo todo el trabajo con un cliente tras otro 👨‍💼⏯.

!!! note "Nota"
    El comando `uvicorn main:app` se refiere a:

    * `main`: el archivo `main.py` (el "módulo" de Python).
    * `app`: el objeto creado dentro de `main.py` con la línea `app = FastAPI()`.
    * `--reload`: hace que el servidor se reinicie cada vez que cambia el código. Úsalo únicamente para desarrollo.

En el output, hay una línea que dice más o menos:

  `I want a clean cup,' interrupted the Hatter:  `let's all move
one place on.'

  He moved on as he spoke, and the Dormouse followed him:  the
March Hare moved into the Dormouse's place, and Alice rather
unwillingly took the place of the March Hare.  The Hatter was the
only one who got any advantage from the change:  and Alice was a

The OkHttp `3.12.x` branch supports Android 2.3+ (API level 9+) and Java 7+. These platforms lack
support for TLS 1.2 and should not be used.
