- Fixed accidental enablement of the new alpha `optionalOldSelf` API field in `CustomResourceDefinition` validation rules, which should only have been allowed to be set when the `CRDValidationRatcheting` feature gate is enabled.

- Allowed setting the `hostnameOverride` field in `PodSpec` to specify any RFC 1123 DNS subdomain as the pod's hostname. The `HostnameOverride` feature gate was introduced to control enablement of this functionality.
