Changelog

[0.19.0]

:rotating_light: Breaking changes

• GeneralizedTime has been renamed to X509GeneralizedTime. The type does not allow fractional seconds, however this restriction is not actually a DER rule, it is specific to X.509. (#494)

• GeneralizedTime is a new type that accepts fractional seconds replacing the old GeneralizedTime. (#492)

• #[derive(asn1::Asn1Read)] and #[derive(asn1::Asn1Write)] now implement "perfect derives". (#496)
