- Kubelet metrics have been changed to buckets. For example the `exec/{podNamespace}/{podID}/{containerName}` is now just exec. ([#87913](https://github.com/kubernetes/kubernetes/pull/87913), [@cheftako](https://github.com/cheftako)) [SIG Node]

- Removes cAdvisor JSON metrics (/stats/container, /stats/<podname>/<containername>, /stats/<namespace>/<podname>/<poduid>/<containername>) from the kubelet. ([#99236](https://github.com/kubernetes/kubernetes/pull/99236), [@pacoxu](https://github.com/pacoxu))

* Added port-forward examples for service

- Added a new feature gate `CheckpointRestore` to enable support to checkpoint containers. If enabled it is possible to checkpoint a container using the newly kubelet API (/checkpoint/{podNamespace}/{podName}/{containerName}).

    * Action required: any Prometheus queries that match `pod_name` and `container_name` labels (e.g. cadvisor or kubelet probe metrics) should be updated to use `pod` and `container` instead. `pod_name` and `container_name` labels will be present alongside `pod` and `container`...
