Якщо у вас стара програма FastAPI з Pydantic v1, нижче я покажу, як мігрувати на Pydantic v2, а також можливості FastAPI 0.119.0, які допоможуть з поступовою міграцією.

## Офіційний посібник { #official-guide }

У Pydantic є офіційний [Посібник з міграції](https://docs.pydantic.dev/latest/migration/) з v1 на v2.

Там описано, що змінилося, як перевірки тепер стали коректнішими та суворішими, можливі застереження тощо.

/**
 * Generates the docbook source for the DSL reference guide.
 *
 * Uses the following as input:
 * <ul>
 * <li>Meta-data extracted from the source by {@link gradlebuild.docs.dsl.source.ExtractDslMetaDataTask}.</li>
 * <li>Meta-data about the plugins, in the form of an XML file.</li>

 * corresponding methods that treat the values as unsigned are found in {@link UnsignedBytes}, and
 * the methods for which signedness is not an issue are in {@link Bytes}.

 * "The .NET Developer's Guide to Windows Security" (which is also
 * available online).

 * Direct ACEs are evaluated first in order. The SID of the user performing
 * the operation and the desired access bits are compared to the SID

Там также описано, что изменилось, как валидации стали более корректными и строгими, возможные нюансы и т.д.

 * <p>In some cases, when speed is more important than code readability, it may be faster simply to
 * treat primitive {@code int} values as unsigned, using the methods from {@link UnsignedInts}.
