## Atributos como listas de submodelos

Você também pode usar modelos Pydantic como subtipos de `list`, `set`, etc:

{* ../../docs_src/body_nested_models/tutorial006.py hl[20] *}

Isso vai esperar(converter, validar, documentar, etc) um corpo JSON tal qual:

```JSON hl_lines="11"
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": [
        "rock",

* `frozenset`:
    * Em requisições e respostas, será tratado da mesma forma que um `set`:
        * Nas requisições, uma lista será lida, eliminando duplicadas e convertendo-a em um `set`.
        * Nas respostas, o `set` será convertido para uma `list`.
        * O esquema gerado vai especificar que os valores do `set` são unicos (usando o `uniqueItems` do JSON Schema).
* `bytes`:
    * O `bytes` padrão do Python.

### Structured logging graduate to Beta

Structured logging reached its Beta milestone. Most log messages from kubelet and kube-scheduler have been converted. Users are encouraged to try out JSON output or parsing of the structured text format and provide feedback on possible solutions for the open issues, such as handling of multi-line strings in log values.

* Volume expansion is now considered Beta. ([#64288](https://github.com/kubernetes/kubernetes/pull/64288),...
