* removed unsafe double RLock in cpumanager ([#62464](https://github.com/kubernetes/kubernetes/pull/62464), [@choury](https://github.com/choury))
* Fix container StartTime in the kubelet's stats/summary endpoint ([#64229](https://github.com/kubernetes/kubernetes/pull/64229), [@dashpole](https://github.com/dashpole))

### Node

* Summary of Container Runtime changes:
  * [beta] [cri-tools](https://github.com/kubernetes-incubator/cri-tools): CLI and validation tools for CRI is now v1.0.0-beta.0. This release mainly focused on UX improvements. [@feiskyer]

### Bug or Regression

- AcceleratorStats will be available in the Summary API of kubelet when cri_stats_provider is used. ([#96873](https://github.com/kubernetes/kubernetes/pull/96873), [@ruiwen-zhao](https://github.com/ruiwen-zhao)) [SIG Node]

- Following metrics have been turned off:
  `apiserver_request_count`
  `apiserver_request_latencies`
  `apiserver_request_latencies_summary`
  `apiserver_dropped_requests`
  `etcd_request_latencies_summary`
  `apiserver_storage_transformation_latencies_microseconds`
  `apiserver_storage_data_key_generation_latencies_microseconds`
  `apiserver_storage_transformation_failures_total`

      - `apiserver_request_latencies` -> `apiserver_request_duration_seconds`
      - `apiserver_dropped_requests` -> `apiserver_dropped_requests_total`
      - `etcd_request_latencies_summary` -> `etcd_request_duration_seconds`
      - `apiserver_storage_transformation_latencies_microseconds ` -> `apiserver_storage_transformation_duration_seconds`

    * This keeps the behavior consistent with Docker integration, and fixes an issue that some container Prometheus metrics don't work when there are summary stats for multiple instances of the same pod.

- Added support for pod `hostNetwork` field selector ([#110477](https://github.com/kubernetes/kubernetes/pull/110477), [@halfcrazy](https://github.com/halfcrazy)) [SIG Apps and Node]
- Added swap to stats to Summary API and Prometheus endpoints (stats/summary and /metrics/resource). ([#118865](https://github.com/kubernetes/kubernetes/pull/118865), [@iholder101](https://github.com/iholder101))

* kubelet: add RSS memory to the summary API ([#24015](https://github.com/kubernetes/kubernetes/pull/24015), [@yujuhong](https://github.com/yujuhong))
* e2e: adapt kubelet_perf.go to use the new summary metrics API ([#24003](https://github.com/kubernetes/kubernetes/pull/24003), [@yujuhong](https://github.com/yujuhong))

* GCE: Fixes ILB sync on legacy networks and auto networks with unique subnet names ([#53410](https://github.com/kubernetes/kubernetes/pull/53410), [@nicksardo](https://github.com/nicksardo))
* Fix the bug that query Kubelet's stats summary with CRI stats enabled results in error. ([#53107](https://github.com/kubernetes/kubernetes/pull/53107), [@Random-Liu](https://github.com/Random-Liu))
