## Offizieller Leitfaden { #official-guide }

Pydantic hat einen offiziellen [Migrationsleitfaden](https://docs.pydantic.dev/latest/migration/) von v1 zu v2.

Er enthält auch, was sich geändert hat, wie Validierungen nun korrekter und strikter sind, mögliche Stolpersteine, usw.

Sie können ihn lesen, um besser zu verstehen, was sich geändert hat.

func (r *Reader) SetExpectedMax(expectedMax int64) {
	r.expectedMax = expectedMax
}

// AddChecksum will add checksum checks as specified in
// https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html
// Returns ErrInvalidChecksum if a problem with the checksum is found.
func (r *Reader) AddChecksum(req *http.Request, ignoreValue bool) error {
	cs, err := GetContentChecksum(req.Header)

You can achieve that using [Pydantic's `AfterValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator) inside of `Annotated`.
