- **Cluster Lifecycle**
  - [alpha] Improved UX and usability for the kubeadm binary that makes it easy to get a new cluster running. ([docs](http://kubernetes.io/docs/getting-started-guides/kubeadm/)) ([changelog](https://github.com/kubernetes/kubeadm/blob/master/CHANGELOG.md)) ([kubernetes/features#11](https://github.com/kubernetes/enhancements/issues/11))

- Structured Authentication Configuration now supports `DiscoveryURL`. If specified, `discoveryURL` overrides the URL used to fetch discovery information. This is for scenarios where the well-known and jwks endpoints are hosted at a different location than the issuer (such as locally in the cluster).

- Fixed bug with leads to Node goes `Not-ready` state when credentials for vCenter stored in a secret and Zones feature is in use. Zone labels setup moved to KCM component, kubelet skips this step during startup in such case. If credentials stored in cloud-provider config file as plaintext current behaviour does not change and no action required. For proper functioning `kube-system:vsphere-legacy-cloud-provider`...

  before updating a cluster where resourceclaims, resourceclaimtemplates, deviceclasses, or resourceslices might have been stored using Kubernetes < 1.32, delete all of those resources before updating and recreate them as needed while running Kubernetes >= 1.32.

- API
  - Ingress resources will no longer be served from `extensions/v1beta1` in v1.19. Migrate use to the `networking.k8s.io/v1beta1` API, available since v1.14. Existing persisted data can be retrieved via the `networking.k8s.io/v1beta1` API.

PodDisruptionBudget handling of "strategic merge patch"-type API requests for the `selector` field. Prior to 1.21, these requests would merge `matchLabels` content and replace `matchExpressions` content. In 1.21, patch requests touching the `selector` field started replacing the entire selector. This is consistent with server-side apply and the v1 PodDisruptionBudget behavior, but should not have been changed for v1beta1.
