cloud-controller-manager has been deprecated, and will be removed in a future release. Use `--secure-port` and `--bind-address` instead. ([#59582](https://github.com/kubernetes/kubernetes/pull/59582), [@sttts](https://github.com/sttts))

* The ability to use the insecure flags `--insecure-bind-address`, `--insecure-port` in the apiserver has been deprecated and will be removed in a future release. Use `--secure-port` and `--bind-address` instead. ([#59018](https://github.com/kubernetes/kubernetes/pull/59018),...

### Feature

- Kubernetes is now built with Golang 1.16.9 (#105672, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]

### Failing Test

- Backport: e2e.test now uses the secure port to retrieve metrics data to ensure compatibility with 1.21 and 1.22 (for upgrade tests) (#104328, @pohly) [SIG API Machinery, Instrumentation, Storage and Testing]

### Bug or Regression

* Adds --append-hash flag to kubectl create configmap/secret, which will append a short hash of the configmap/secret contents to the name during creation. ([#49961](https://github.com/kubernetes/kubernetes/pull/49961), [@mtaufen](https://github.com/mtaufen))

- The Scheduler did not run the plugin Score method when its PreScore method returned a Skip status. In other words, the PreScore/Score plugin could return a Skip status in PreScore if the plugin did nothing in Score for that Pod. ([#115652](https://github.com/kubernetes/kubernetes/pull/115652), [@AxeZhan](https://github.com/AxeZhan))

- Secure serving on port 10258 to cloud-controller-manager (configurable via `--secure-port`) is now enabled. Delegated authentication and authorization are to be configured using the same flags as for aggregated API servers. Without configuration, the secure port will only allow access to `/healthz`.

#### kubectl:

* Adds --append-hash flag to kubectl create configmap/secret, which will append a short hash of the configmap/secret contents to the name during creation. ([#49961](https://github.com/kubernetes/kubernetes/pull/49961), [@mtaufen](https://github.com/mtaufen))

  
  Changed `kubectl create secret --help` description. There will be a short introduction to the three secret types and clearer guidance on how to use the command. ([#117930](https://github.com/kubernetes/kubernetes/pull/117930), [@LronDC](https://github.com/LronDC))
- The scheduler skips the `InterPodAffinity` Score plugin when nothing to do with the Pod.

- Kubeadm: reset raises warnings if it cannot delete folders ([#85265](https://github.com/kubernetes/kubernetes/pull/85265), [@SataQiu](https://github.com/SataQiu))

* kubeadm: kubelets in kubeadm clusters now disable the readonly port (10255). If you're relying on unauthenticated access to the readonly port, please switch to using the secure port (10250). Instead, you can now use ServiceAccount tokens when talking to the secure port, which will make it easier to get access to, for example, the `/metrics` endpoint of the kubelet, securely.
