- kubeadm: Always pass spec.nodeName as `--hostname-override` for kube-proxy ([#71283](https://github.com/kubernetes/kubernetes/pull/71283), [@Klaven](https://github.com/Klaven))
- `kubeadm join` correctly uses `--node-name` and `--cri-socket` when `--config` option is also used ([#71270](https://github.com/kubernetes/kubernetes/pull/71270), [@bart0sh](https://github.com/bart0sh))

    /** The key of the configuration. e.g. true */
    String RESPONSE_HIGHLIGHT_content_title_ENABLED = "response.highlight.content_title.enabled";

    /** The key of the configuration. e.g. application/pdf,text/plain */
    String RESPONSE_INLINE_MIMETYPES = "response.inline.mimetypes";

    /** The key of the configuration. e.g. fess.search */
    String INDEX_DOCUMENT_SEARCH_INDEX = "index.document.search.index";

  - `kubeadm config upload` has been deprecated, as its replacement is now graduated. Please use `kubeadm init phase upload-config` instead. ([#77946](https://github.com/kubernetes/kubernetes/pull/77946), [@Klaven](https://github.com/Klaven))

- The following features are now GA, and the associated feature gates are deprecated and will be removed in v1.17:
  - `GCERegionalPersistentDisk`

## Metrics Changes

### Added metrics

- kubeadm reset: unmount directories under `/var/lib/kubelet` for Linux only ([#81494](https://github.com/kubernetes/kubernetes/pull/81494), [@Klaven](https://github.com/Klaven))
- kubeadm: fix the bug that `--cri-socket` flag does not work for `kubeadm reset` ([#79498](https://github.com/kubernetes/kubernetes/pull/79498), [@SataQiu](https://github.com/SataQiu))

## Deprecations and Removals
- `kubeadm.k8s.io/v1beta1` has been deprecated, you should update your config to use newer non-deprecated API versions. ([#83276](https://github.com/kubernetes/kubernetes/pull/83276), [@Klaven](https://github.com/Klaven))

So, a request with a content type of `text/plain` containing JSON data would be accepted and the JSON data would be extracted.

- Hashing of KeyID in Logs
  

- Modified command line errors (for example, `kubectl list` -> `unknown command`) that were printed as log message with escaped line breaks instead of a multi-line plain text, making the error hard to read. ([#107044](https://github.com/kubernetes/kubernetes/pull/107044), [@pohly](https://github.com/pohly))

### SIG vSphere

* Added a mechanism in vSphere Cloud Provider to get credentials from Kubernetes secrets, rather than the plain text `vsphere.conf` file.([#63902](https://github.com/kubernetes/kubernetes/pull/63902), [@abrarshivani](https://github.com/abrarshivani))

as a numeric constant: <code>\x</code> followed by exactly two hexadecimal
digits; <code>\u</code> followed by exactly four hexadecimal digits;
<code>\U</code> followed by exactly eight hexadecimal digits, and a
plain backslash <code>\</code> followed by exactly three octal digits.
In each case the value of the literal is the value represented by
the digits in the corresponding base.
