- The legacy scheduler policy config is removed in v1.23, the associated flags `policy-config-file`, `policy-configmap`, `policy-configmap-namespace` and `use-legacy-policy-config` are also removed. Migrate to Component Config instead, see https://kubernetes.io/docs/reference/scheduling/config/ for details. ([#105424](https://github.com/kubernete...

  * PodSecurityPolicy admission sets `podsecuritypolicy.admission.k8s.io/admit-policy` and `podsecuritypolicy.admission.k8s.io/validate-policy` annotations containing the name of the policy that allowed a pod to be admitted. (PodSecurityPolicy also gained the ability to [limit hostPath volume mounts to be read-only](https://kubernetes.io/docs/concepts/policy/pod-security-policy/#volumes-and-file-systems).)

// registrations (clause 11 "allocated subdomains" in the 2006 TLD
// policy), but the relevant industry partners have not opened them up
// for registration. Current status can be determined from the TLD's
// policy document: 2LDs that are open for registration must list
// their policy in the TLD's policy. Any 2LD without such a policy is
// not open for registrations.

from 1.4 to 1.5, you must delete all `PodDisruptionBudget` objects (`policy/v1alpha1/PodDisruptionBudget`) that you have created. It is not possible to delete these objects after you upgrade, and their presence will prevent you from using the beta PodDisruptionBudget feature in 1.5 (which uses `policy/v1beta1/PodDisruptionBudget`). If you have already upgraded, you will need to downgrade the master to 1.4 to delete the `policy/v1alpha1/PodDisruptionBudget` objects.

- Reverted the `DisableNodeKubeProxyVersion` feature gate to default-off to give a full year from deprecation announcement in 1.29 to clearing the field by default, per the [Kubernetes deprecation policy](https://kubernetes.io/docs/reference/using-api/deprecation-policy/).
