#### Removed Deprecations

- The kube-apiserver ability to serve on an insecure port, deprecated since v1.10, has been removed. The insecure address flags `--address` and `--insecure-bind-address` have no effect in kube-apiserver and will be removed in v1.24. The insecure port flags `--port` and `--insecure-port` may only be set to 0 and will be removed in v1.24. ([#95856](https://github.com/kubernetes/kubernetes/pull/95856), [@knight42](https://github.com/knight42), [SIG API Machinery,...

  * Remove PodSandboxStatus.Linux.Namespaces.Network from CRI since it is not used/needed. ([#45166](https://github.com/kubernetes/kubernetes/pull/45166), [@feiskyer](https://github.com/feiskyer))

- kube-controller-manager
  - The deprecated `--insecure-experimental-approve-all-kubelet-csrs-for-group` flag has been removed.
- kubelet

* The following deprecated flags were removed from `kubelet`:

  * `api-servers` - add apiserver addresses to the kubeconfig file instead.

  Don't use these flags. Using deprecated flags causes the kubelet to print a warning. Using a removed flag causes the kubelet to abort the startup.
