New features include improved integration between the Keystone service and Kubernetes RBAC, and a number of stability and compatibility improvements across the entire provider code-base.

### SIG Scheduling

- Added kubelet support for systemd watchdog integration. With this enabled, systemd can automatically recover a hung kubelet. ([#127566](https://github.com/kubernetes/kubernetes/pull/127566), [@zhifei92](https://github.com/zhifei92)) [SIG Cloud Provider, Node and Testing]

- Replaced deprecated package `k8s.io/utils/pointer` with `k8s.io/utils/ptr` for ./test/integration. ([#132762](https://github.com/kubernetes/kubernetes/pull/132762), [@PatrickLaabs](https://github.com/PatrickLaabs))

* [alpha] Adds support of container metrics in CRI ([docs PR](https://github.com/kubernetes/community/pull/742)) ([kubernetes/features#290](https://github.com/kubernetes/enhancements/issues/290))

- 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 such as containerd and cri-o. 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.

- Removed legacy cloud provider integration code (undoing a previous reverted commit). ([#124886](https://github.com/kubernetes/kubernetes/pull/124886), [@carlory](https://github.com/carlory)) [SIG Cloud Provider and Release]

### API Change

- Enhanced cloud provider integrations to support optional, per-Node custom labels that can be supplied and applied to Nodes by the node controller. These extra labels will only be applied where the cloud provider integration supports this feature.

- Fixed an issue which prevented `gcloud` from working on GCE when metadata concealment was enabled. ([#66630](https://github.com/kubernetes/kubernetes/pull/66630), [@dekkagaijin](https://github.com/dekkagaijin))
- Fix Stackdriver integration based on node annotation container.googleapis.com/instance_id. ([#66676](https://github.com/kubernetes/kubernetes/pull/66676), [@kawych](https://github.com/kawych))
