* If a pod has a running instance, the stats of its previously terminated instances will not show up in the kubelet summary stats any more for CRI runtimes like containerd and cri-o. ([#77426](https://github.com/kubernetes/kubernetes/pull/77426), [@Random-Liu](https://github.com/Random-Liu))

- Bumped `KubeletCgroupDriverFromCRI` to GA and add metric to track out-of-support CRI implementations. ([#133157](https://github.com/kubernetes/kubernetes/pull/133157), [@haircommander](https://github.com/haircommander)) [SIG Node and Testing]

- Extended ContainerStatus CRI API to allow runtime response with container resource requests and limits that are in effect.
  - UpdateContainerResources CRI API now supports both Linux and Windows. ([#111645](https://github.com/kubernetes/kubernetes/pull/111645), [@vinaykul](https://github.com/vinaykul))

- Docker support in the kubelet is now deprecated and will be removed in a future release. The kubelet uses a module called "dockershim" which implements CRI support for Docker and it has seen maintenance issues in the Kubernetes community. We encourage you to evaluate moving to a container runtime that is a full-fledged implementation of CRI (v1alpha1 or v1 compliant) as they become available.
