Antes do FastAPI 0.108.0, Starlette 0.29.0, `name` era o primeiro parâmetro.

Além disso, em versões anteriores, o objeto `request` era passado como parte dos pares chave-valor no "context" dict para o Jinja2.

/// info | Información

Ten en cuenta que la parte más importante para hacer un parámetro opcional es la parte:

```Python
= None
```

o la parte:

```Python
= Query(default=None)
```

ya que usará ese `None` como el valor por defecto, y de esa manera hará el parámetro **no requerido**.
