docs/ru/docs/how-to/migrate-from-pydantic-v1-to-pydantic-v2.md

Если у вас старое приложение FastAPI, возможно, вы используете Pydantic версии 1.

FastAPI поддерживает и Pydantic v1, и v2 начиная с версии 0.100.0.

Если у вас был установлен Pydantic v2, использовался он. Если вместо этого был установлен Pydantic v1 — использовался он.
