* Remove deprecated vagrant kube-up.sh. ([#58118](https://github.com/kubernetes/kubernetes/pull/58118),[@roberthbailey](https://github.com/roberthbailey))

### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.
2) Alpha for CSI specification 0.3 integration to AWS EBS (Elastic Block Store)

resources such as secrets, a mechanism to store resource encryption keys in external Key Management Systems (KMS) was introduced. This complements the original file-based storage and allows integration with multiple KMS. A Google Cloud KMS plugin was added and will be usable once the Google side of the integration is complete.

* Websocket requests may now authenticate to the API server by passing a bearer token in a websocket subprotocol of the form `base64url.bearer.authorization.k8s....

- 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]

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

- 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. ([#77426](https://github.com/kubernetes/kubernetes/pull/77426), [@Random-Liu](https://github.com/Random-Liu))...

- 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.
   ([#123223](https://github.com/kubernetes/kubernetes/pull/123223), [@mmerkes](https://github.com/mmerkes))

- 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]
