* Remove duplicate command example from `kubectl port-forward --help` ([#50229](https://github.com/kubernetes/kubernetes/pull/50229), [@tcharding](https://github.com/tcharding))
* Adds a new `kubeadm config` command that lets users tell `kubeadm upgrade` what kubeadm configuration to use and lets users view the current state. ([#50980](https://github.com/kubernetes/kubernetes/pull/50980), [@luxas](https://github.com/luxas))

- Kubeadm: if the user has customized their image repository via the kubeadm configuration, pass the custom pause image repository and tag to the kubelet via --pod-infra-container-image not only for Docker but for all container runtimes. This flag tells the kubelet that it should not garbage collect the image.

#### **IPVS**

*   You can now use the --cleanup-ipvs flag to tell kube-proxy whether to flush all existing ipvs rules in on startup ([#56036](https://github.com/kubernetes/kubernetes/pull/56036),[ @m1093782566](https://github.com/m1093782566))

* You must now specify `Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey` when using dynamic Kubelet config to tell the Kubelet which key of the `ConfigMap` identifies its config file. ([#59847](https://github.com/kubernetes/kubernetes/pull/59847), [@mtaufen](https://github.com/mtaufen))

- Added a `kubernetes_feature_enabled` metric which will tell you if a feature is enabled. ([#112652](https://github.com/kubernetes/kubernetes/pull/112652), [@logicalhan](https://github.com/logicalhan))
