- Remove the deprecated flag `--experimental-check-node-capabilities-before-mount`. With CSI now GA, there is a better alternative. Remove any use of  `--experimental-check-node-capabilities-before-mount` from your kubelet scripts or manifests. ([#104732](https://github.com/kubernetes/kubernetes/pull/104732), [@mengjiao-liu](https://github.com/mengjiao-liu))

- Kubernetes is now built with Go `v1.21.3`. ([#121149](https://github.com/kubernetes/kubernetes/pull/121149), [@cpanato](https://github.com/cpanato))
- List of metric labels can now be configured by supplying a manifest using the `--allow-metric-labels-manifest` flag. ([#118299](https://github.com/kubernetes/kubernetes/pull/118299), [@rexagod](https://github.com/rexagod))

- kubeadm: removed the deprecated and NO-OP flags `--feature-gates` for `kubeadm upgrade apply` and `--api-server-manifest`, `--controller-manager-manifest`, and `--scheduler-manifest` for `kubeadm upgrade diff`. ([#127123](https://github.com/kubernetes/kubernetes/pull/127123), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

- Kubeadm: fixed a bug where the path of the manifest can not be specified when `kubeadm upgrade diff` specified a config file, and the `--api-server-manifest`, `--controller-manager-manifest` and `--scheduler-manifest` flags of `kubeadm upgrade diff` are marked as deprecated and will be removed in a future release. ([#125779](https://github.com/kubernetes/kubernetes/pull/125779),...

- `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))

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

  - 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.

* Fixes `kubectl create secret docker-registry` compatibility ([#72344](https://github.com/kubernetes/kubernetes/pull/72344), [@liggitt](https://github.com/liggitt))
* Add-on manifests now use the apps/v1 API for DaemonSets, Deployments, and ReplicaSets ([#72203](https://github.com/kubernetes/kubernetes/pull/72203), [@liggitt](https://github.com/liggitt))

- Kubeadm: add the flag "--experimental-initial-corrupt-check" to etcd static Pod manifests to ensure etcd member data consistency ([#109076](https://github.com/kubernetes/kubernetes/pull/109076), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
