- Changed how KMS v2 encryption at rest can generate data encryption keys.

   * **NOTE:** Self-hosting will be the default way to host the control plane in the next release, v1.9

* [alpha] A new `phase` subcommand supports performing only subtasks of the full `kubeadm init` flow. Combined with fine-grained configuration, kubeadm is now more easily consumable by higher-level provisioning tools like kops or GKE.

- CEL regex patterns in x-kubernetes-valiation rules are compiled when CRDs are created/updated if the pattern is provided as a string constant in the expression. Any regex compile errors are reported as a CRD create/update validation error. ([#108617](https://github.com/kubernetes/kubernetes/pull/108617), [@jpbetz](https://github.com/jpbetz))

We expect this implementation to progress from alpha to beta and GA in coming releases, so we’re eager to have you comment about your dual-stack experiences in [#k8s-dual-stack](https://kubernetes.slack.com/messages/k8s-dual-stack) or in [enhancements #563](https://features.k8s.io/563).
