- Added `optionalOldSelf` to `x-kubernetes-validations` to support ratcheting CRD schema constraints. ([#121034](https://github.com/kubernetes/kubernetes/pull/121034), [@alexzielenski](https://github.com/alexzielenski))
- Added a new `ServiceCIDR` type that allows to dynamically configure the cluster range used to allocate `Service ClusterIPs` addresses. ([#116516](https://github.com/kubernetes/kubernetes/pull/116516), [@aojea](https://github.com/aojea))
