- `kubeadm`: Started using a named port `probe-port` for all probes in the static pod manifests generated by `kubeadm` for the `kube-apiserver`, `kube-controller-manager`, `kube-scheduler`, and related components. If probe port values were previously patched using `kubeadm` patches, the corresponding named port under the container’s `ports`...

* hyperkube

  * The hyperkube image has been slimmed down and no longer includes addon manifests and other various scripts. These were introduced for the now removed docker-multinode setup system. ([#44555](https://github.com/kubernetes/kubernetes/pull/44555), [@luxas](https://github.com/luxas))

* Check for known manifests during preflight instead of only checking for non-empty manifests directory. ([#57287](https://github.com/kubernetes/kubernetes/pull/57287), [@mattkelly](https://github.com/mattkelly))

- Kubeadm: removed the usage of the `--container-runtime=remote` flag for the kubelet during kubeadm init/join/upgrade. The flag value...

- `kubeadm`: speedup init by 0s or 20s. kubelet-start phase is now after etcd
  and control-plane phases, removing a race condition between kubelet looking for
  static pod manifests and kubeadm writing them. ([#117984](https://github.com/kubernetes/kubernetes/pull/117984), [@champtar](https://github.com/champtar))

  - Apply toleration for a new, future taint "node-role.kubernetes.io/control-plane:NoSchedule" to the kubeadm CoreDNS / kube-dns managed manifests. Note that this taint is not yet applied to kubeadm control-plane nodes.
  - Please adapt your workloads to tolerate the same future taint preemptively.
    
- Kubeadm: improve the validation of serviceSubnet and podSubnet.
