Das liegt daran, dass FastAPI standardmäßig jedes enthaltene Element überprüft und sicherstellt, dass es als JSON serialisierbar ist, und zwar unter Verwendung desselben [JSON-kompatiblen Encoders](../tutorial/encoder.md){.internal-link target=_blank}, der im Tutorial erläutert wurde. Dadurch können Sie **beliebige Objekte** zurückgeben, zum Beispiel Datenbankmodelle.

Isso ocorre por que, por padrão, o FastAPI irá verificar cada item dentro do dicionário e garantir que ele seja serializável para JSON, utilizando o mesmo[Codificador Compatível com JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado no tutorial. Isso permite que você retorne **objetos abstratos**, como modelos do banco de dados, por exemplo.

    had an off-by-one bug in our HPACK encoder. This bug could have caused the
    wrong headers to be emitted after a sequence of HTTP/2 requests! Everyone
    who is using OkHttp 3.4.0 or 3.4.0-RC1 should upgrade for this bug fix.


## Version 3.4.0

_2016-07-08_

 *  New: Support dynamic table size changes to HPACK Encoder.
