- Kubeadm: fix the bug that configurable KubernetesVersion not respected during kubeadm join ([#111024](https://github.com/kubernetes/kubernetes/pull/111024), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
- Reduced time taken to sync proxy rules on Windows kube-proxy with kernelspace mode ([#110701](https://github.com/kubernetes/kubernetes/pull/110701), [@daschott](https://github.com/daschott)) [SIG Network and Windows]

- Pods will now post their readiness during termination. ([#110191](https://github.com/kubernetes/kubernetes/pull/110191), [@rphillips](https://github.com/rphillips)) [SIG Network, Node and Testing]
- Reduced time taken to sync proxy rules on Windows kube-proxy with kernelspace mode ([#109124](https://github.com/kubernetes/kubernetes/pull/109124), [@daschott](https://github.com/daschott)) [SIG Network, Release and Windows]

    * => IPv6 BackendPool name == <clusterName>-IPv6
    * This result into:
    * - clusters moving from IPv4 to duakstack will require no changes
    * - clusters moving from IPv6 (while not seen in the wild, we can not rule out their existence) to dualstack will require deleting backend pools (the reconciler will take care of creating correct backendpools)

- Fixes a `cannot convert int64 to float64` error seen using server-side apply with certain CRDs in 1.19.10+ ([#103105](https://github.com/kubernetes/kubernetes/pull/103105), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]
