Kubernetes images. The old registry (`k8s.gcr.io`) will continue to be supported for the foreseeable future, but the new name should perform better because it frontends equivalent mirrors in other clouds.  Please point your clusters to the new registry going forward. \n\nAdmission/Policy integrations that have an allowlist of registries need to include `registry.k8s.io` alongside `k8s.gcr.io`.\nAir-gapped environments and image garbage-collection configurations will need to update to pre-pull and preserve...

* Add PriorityClass API object under new "scheduling" API group ([#48377](https://github.com/kubernetes/kubernetes/pull/48377), [@bsalamat](https://github.com/bsalamat))
* Added golint check for pkg/kubelet. ([#47316](https://github.com/kubernetes/kubernetes/pull/47316), [@k82cn](https://github.com/k82cn))

      exists in k/k repo since we removed federation/, and I don't see it
      in https://github.com/kubernetes-sigs/kubefed/ either. I'm assuming
      that it's gone for good now.

- Kubeadm: The ClusterStatus struct present in the kubeadm-config ConfigMap is deprecated and will be removed on a future version. It is going to be maintained by kubeadm until it gets removed. The same information can be found on `etcd` and `kube-apiserver` pod annotations, `kubeadm.kubernetes.io/etcd.advertise-client-urls` and `kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint`...

In some cases, for pure data validation and processing, you can get performance improvements of **20x** or more. This means 2,000% or more. 🤯

When you use **FastAPI**, there's a lot more going on, processing the request and response, handling dependencies, executing **your own code**, and particularly, **waiting for the network**. But you will probably still get some nice performance improvements just from the upgrade.

- [API Server Network Proxy](https://github.com/kubernetes/enhancements/blob/master/keps/sig-api-machinery/1281-network-proxy/README.md) going alpha in 1.16.

We should be able to simplify the rules for comparable or delegate some of them
elsewhere since we have a section that clearly defines how interfaces implement
other interfaces based on their type sets. But this should get us going for now.
