- Kubeadm: apply `second stage` of the plan to migrate kubeadm away from the usage of the word `master` in labels and taints. For new clusters, the label `node-role.kubernetes.io/master` will no longer be added to control plane nodes, only the label `node-role.kubernetes.io/control-plane`...

- Kubeadm: the `kubelet-finalize` phase of `kubeadm init` no longer requires the kubelet kubeconfig to have a specific authinfo. ([#123171](https://github.com/kubernetes/kubernetes/pull/123171), [@vrutkovs](https://github.com/vrutkovs))

  installing `kubeadm` will no longer automatically ensure installation of `crictl`. ([#124685](https://github.com/kubernetes/kubernetes/pull/124685), [@saschagrunert](https://github.com/saschagrunert))

   *
   * <p>The resulting stream will only be as long as the shorter of the two input streams; if one
   * stream is longer, its extra elements will be ignored.
   *
   * <p>Note that if you are calling {@link Stream#forEach} on the resulting stream, you might want
   * to consider using {@link #forEachPair} instead of this method.

  - `pathType` no longer has a default value in v1; "Exact", "Prefix", or "ImplementationSpecific" must be specified

  Other Ingress API updates:
  - backends can now be resource or service backends

    // Starting with an 8k buffer, double the size of each successive buffer. Smaller buffers
    // quadruple in size until they reach 8k, to minimize the number of small reads for longer
    // streams. Buffers are retained in a deque so that there's no copying between buffers while
    // reading and so all of the bytes in each new allocated buffer are available for reading from
    // the stream.
