- CRD supports multi-version Schema, Subresources and AdditionalPrintColumns (NOTE that CRDs created prior to 1.13 populated the top-level additionalPrinterColumns field by default. To apply an updated that changes to per-version additionalPrinterColumns, the top-level additionalPrinterColumns field must be explicitly set to null).

correctly reports impersonated user info. ([#48184](https://github.com/kubernetes/kubernetes/pull/48184), [@CaoShuFeng](https://github.com/CaoShuFeng))

* Advanced audit policy now supports matching subresources and resource names, but the top level resource no longer matches the subresouce. For example "pods" no longer matches requests to the logs subresource of pods. Use "pods/logs" to match subresources.

need for a debug utility for quite some time already. With the development of [ephemeral containers](https://kubernetes.io/docs/concepts/workloads/pods/ephemeral-containers/), it became more obvious how we can support developers with tooling built on top of `kubectl exec`. The addition of the `kubectl debug` [command](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/1441-kubectl-debug/README.md) (it is alpha but your feedback is more than welcome), allows developers to easily debug...

*   `kubectl get` now uses OpenAPI schema extensions by default to select columns for custom types. ([#53483](https://github.com/kubernetes/kubernetes/pull/53483),[ @apelisse](https://github.com/apelisse))
*   kubectl `top node` now sorts by name and `top pod` sorts by namespace. Fixed a bug where results were inconsistently sorted. ([#53560](https://github.com/kubernetes/kubernetes/pull/53560),[ @dixudx](https://github.com/dixudx))

- Added a `--show-swap` option to `kubectl top` subcommands ([#129458](https://github.com/kubernetes/kubernetes/pull/129458), [@iholder101](https://github.com/iholder101)) [SIG CLI]

of Heapster. Instead, you may use the [metrics server](https://github.com/kubernetes-incubator/metrics-server). It's a simplified heapster that is able to gather and serve current metrics values. It provides the Metrics API that is used by `kubectl top`, and horizontal pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs in kube-dashboard and dedicated push sinks, which proved hard to maintain and scale. Clusters using Heapster for transferring...

* Fix fluentd-gcp configuration to facilitate JSON parsing ([#48139](https://github.com/kubernetes/kubernetes/pull/48139), [@crassirostris](https://github.com/crassirostris))
* Bump runc to v1.0.0-rc2-49-gd223e2a - fixes `failed to initialise top level QOS containers` kubelet error. ([#48117](https://github.com/kubernetes/kubernetes/pull/48117), [@sjenning](https://github.com/sjenning))

* kubeadm: Make kube-proxy tolerate the external cloud provider taint so that an external cloud provider can be easily used on top of kubeadm ([#49017](https://github.com/kubernetes/kubernetes/pull/49017), [@luxas](https://github.com/luxas))
