## Pydantic v1 no v2 { #pydantic-v1-in-v2 }

O Pydantic v2 inclui tudo do Pydantic v1 como um submódulo `pydantic.v1`.

Isso significa que você pode instalar a versão mais recente do Pydantic v2 e importar e usar os componentes antigos do Pydantic v1 a partir desse submódulo, como se tivesse o Pydantic v1 antigo instalado.
