O Pydantic tem um <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">Guia de Migração</a> oficial do v1 para o v2.

Ele também inclui o que mudou, como as validações agora são mais corretas e rigorosas, possíveis ressalvas, etc.

Если у вас старое приложение FastAPI с Pydantic v1, здесь я покажу, как мигрировать на Pydantic v2, и **новые возможности в FastAPI 0.119.0**, которые помогут выполнить постепенную миграцию.

## Официальное руководство { #official-guide }

У Pydantic есть официальное <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">руководство по миграции</a> с v1 на v2.

In the case of Spanish, the 2-letter code is `es`. So, the directory for Spanish translations is located at `docs/es/`.

/// tip

The main ("official") language is English, located at `docs/en/`.

Now run the live server for the docs in Spanish:
