- Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))

### **Cluster Lifecycle**

*   kube-apiserver: `--ssh-user` and `--ssh-keyfile` are now deprecated and will be removed in a future release. Users of SSH tunnel functionality in Google Container Engine for the Master -> Cluster communication should plan alternate methods for bridging master and node networks. ([#54433](https://github.com/kubernetes/kubernetes/pull/54433),[ @dims](https://github.com/dims))

- When initializing nodes using external cloud-providers, the process now waits for the providerID value to be available before declaring the node ready. This ensures that nodes are not marked as Ready prematurely due to communication errors with the cloud-provider. The providerID and zone labels are necessary for integrations such as load balancers to function correctly. Users can choose to opt out of this behavior by setting the feature flag OptionalProviderID in the clou...

* Ignore pods marked for deletion that exceed their grace period in ResourceQuota ([#46542](https://github.com/kubernetes/kubernetes/pull/46542), [@derekwaynecarr](https://github.com/derekwaynecarr))
* kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs ([#52176](https://github.com/kubernetes/kubernetes/pull/52176), [@liggitt](https://github.com/liggitt))

* Update to go 1.12.10 ([#83139](https://github.com/kubernetes/kubernetes/pull/83139), [@cblecker](https://github.com/cblecker))

* Ensure euqiv hash calculation is per schedule ([#59245](https://github.com/kubernetes/kubernetes/pull/59245), [@resouer](https://github.com/resouer))

* Upped the timeout for apiserver communication in the juju kubernetes-worker charm. ([#59219](https://github.com/kubernetes/kubernetes/pull/59219), [@hyperbolic2346](https://github.com/hyperbolic2346))

`docker` service from kubeadm preflight. Docker is no longer special cased during host validation and ideally this task should be done in the now external cri-dockerd project where the importance of the compatibility matters. Use `crictl` for all communication with CRI sockets for actions like pulling images and obtaining a list of running containers instead of using the docker CLI in the case of Docker.

* Introduce policy to allow the HPA to consume the metrics.k8s.io and custom.metrics.k8s.io API groups. ([#52572](https://github.com/kubernetes/kubernetes/pull/52572), [@DirectXMan12](https://github.com/DirectXMan12))
