The network requests also contain more data, such as the `Accept-Encoding: gzip` header added by OkHttp to advertise support for response compression. The network interceptor's `Chain` has a non-null `Connection` that can be used to interrogate the IP address and TLS configuration that were used to connect to the webserver.

- kubeadm: Added a `v1beta1` API. ([#69289](https://github.com/kubernetes/kubernetes/pull/69289), [@fabriziopandini](https://github.com/fabriziopandini))
- kubeadm: Use `advertise-client-urls` instead of `listen-client-urls` as and `etcd-servers` options for apiserver. ([#69827](https://github.com/kubernetes/kubernetes/pull/69827), [@tomkukral](https://github.com/tomkukral))

- kubeadm: make the command "kubeadm alpha kubeconfig user" accept a "--config" flag and remove the following flags:
  - apiserver-advertise-address / apiserver-bind-port: use either localAPIEndpoint from InitConfiguration or controlPlaneEndpoint from ClusterConfiguration.
  - cluster-name: use clusterName from ClusterConfiguration

- Resolves a transient 404 response to custom resource requests during server startup ([#81244](https://github.com/kubernetes/kubernetes/pull/81244), [@liggitt](https://github.com/liggitt))
- OpenAPI now advertises correctly supported patch types for custom resources ([#81515](https://github.com/kubernetes/kubernetes/pull/81515), [@liggitt](https://github.com/liggitt))

- kubeadm: consider --bind-address or --advertise-address and --secure-port for control plane components when the feature gate WaitForAllControlPlaneComponents is enabled. Use /livez for kube-apiserver and kube-scheduler, but continue using /healthz for kube-controller-manager until it supports...
