- Kubectl [get and describe](https://github.com/kubernetes/enhancements/issues/515) now works with extensions
- Nodes now support [third party monitoring plugins](https://github.com/kubernetes/enhancements/issues/606).

* `kubectl auth reconcile` only works with rbac.v1; all the core helpers have been switched over to use the external types. ([#63967](https://github.com/kubernetes/kubernetes/pull/63967), [@deads2k](https://github.com/deads2k))

* **[alpha]** New Bootstrap Token authentication and management method. Works well with kubeadm. kubeadm now supports managing tokens, including time based expiration, after the cluster is launched.  See [kubeadm reference docs](https://kubernetes.io/docs/admin/kubeadm/#manage-tokens) for details.

* fix the error prone account creation method of blob disk ([#59739](https://github.com/kubernetes/kubernetes/pull/59739), [@andyzhangx](https://github.com/andyzhangx))
* The webhook admission controller in a custom apiserver now works off-the-shelf. ([#60995](https://github.com/kubernetes/kubernetes/pull/60995), [@caesarxuchao](https://github.com/caesarxuchao))

   * Glob patterns must be unique, if there's a clash assign to the most
     popular format
   * The main mime type should be the canonical one, use aliases for any
     other widely used forms
   * Where there's a hierarchy in the types, list it via a parent
   * Highly specific magic matches get a high priority
   * General magic matches which could trigger a false-positive need
     a low one

### Cluster Lifecycle

- The `auto-detect` behavior of the kubelet's `--cloud-provider` flag is deprecated.

  - In version 1.8, the default value for the kubelet's `--cloud-provider` flag is `auto-detect`. Be aware that it works only on GCE, AWS and Azure.

  - In version 1.9, the default will be `""`, which means no built-in cloud provider extension will be enabled by default.

- `kubectl create secret tls` can now read certificate and key files from process substitution arguments ([#67713](https://github.com/kubernetes/kubernetes/pull/67713), [@liggitt](https://github.com/liggitt))
- `kubectl rollout status` now works for unlimited timeouts. ([#67817](https://github.com/kubernetes/kubernetes/pull/67817), [@tnozicka](https://github.com/tnozicka))

### SIG Cloud Provider

- Kubectl: --resource-version now works properly in label/annotate/set selector commands when racing with other clients to update the target object ([#85285](https://github.com/kubernetes/kubernetes/pull/85285), [@liggitt](https://github.com/liggitt))

- Enabled kube-controller-manager '--concurrent-job-syncs' flag works on orphan Pod processors ([#126567](https://github.com/kubernetes/kubernetes/pull/126567), [@fusida](https://github.com/fusida)) [SIG Apps]
