* Bug fixes:

  * Fix corner-case with OnlyLocal Service healthchecks. ([#44313](https://github.com/kubernetes/kubernetes/pull/44313), [@thockin](https://github.com/thockin))

- Kubeadm: enable the usage of the secure kube-scheduler and kube-controller-manager ports for health checks. For kube-scheduler was 10251, becomes 10259. For kube-controller-manager was 10252, becomes 10257. ([#85043](https://github.com/kubernetes/kubernetes/pull/85043), [@neolit123](https://github.com/neolit123))

- If `ComponentSLIs` feature gate is enabled, then `/metrics/slis` becomes available on kubelet, allowing you to scrape health check metrics. ([#113030](https://github.com/kubernetes/kubernetes/pull/113030), [@Richabanker](https://github.com/Richabanker)) [SIG Node]

### API Change

- A new alpha feature gate, `MutableCSINodeAllocatableCount`, has been introduced.
  

kube-apiserver. The "kubeadm join" workflow now includes a new experimental phase called "wait-control-plane". This phase will be marked as non-experimental when WaitForAllControlPlaneComponents becomes GA. Accordingly a "kubeadm init" phase "wait-control-plane" will also be available once WaitForAllControlPlaneComponents becomes GA. These phases can be skipped if the user prefers to not wait for the control plane components. ([#123341](https://github.com/kubernetes/kubernetes/pull/123341), [@neolit123](http...

([#64706](https://github.com/kubernetes/kubernetes/pull/64706), [@liztio](https://github.com/liztio))

  - kube_apiserver_pod_logs_pods_logs_backend_tls_failure_total becomes kube_apiserver_pod_logs_backend_tls_failure_total
  - kube_apiserver_pod_logs_pods_logs_insecure_backend_total becomes kube_apiserver_pod_logs_insecure_backend_total ([#114497](https://github.com/kubernetes/kubernetes/pull/114497), [@dgrisonnet](https://github.com/dgrisonnet))

- `kubeadm`: improved the logic that checks whether a `systemd` service exists. ([#120514](https://github.com/kubernetes/kubernetes/pull/120514), [@fengxsong](https://github.com/fengxsong))
- `kubeadm`: will now use universal deserializer to decode static pod. ([#120549](https://github.com/kubernetes/kubernetes/pull/120549), [@pacoxu](https://github.com/pacoxu))
- `kubectl prune v2`: Switched annotation from `contains-group-resources` to `contains-group-kinds`,

* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))
* kube-apiserver would return 400 Bad Request when it couldn't decode a json patch. ([#68346](https://github.com/kubernetes/kubernetes/pull/68346), [@CaoShuFeng](https://github.com/CaoShuFeng))
    * kube-apiserver would return 422 Unprocessable Entity when a json patch couldn't be applied to one object.

    * `externalTrafficPolicy` field, the values chnag as follows:
          * "OnlyLocal" becomes "Local"
          * "Global" becomes "Cluster".
* Fix kubelet reset liveness probe failure count across pod restart boundaries ([#46371](https://github.com/kubernetes/kubernetes/pull/46371), [@sjenning](https://github.com/sjenning))
