* Node-Problem-Detector configuration is now decoupled from the Kubernetes release on GKE/GCE. ([#73288](https://github.com/kubernetes/kubernetes/pull/73288), [@wangzhen127](https://github.com/wangzhen127))
* Restores --username and --password flags to kubectl ([#75451](https://github.com/kubernetes/kubernetes/pull/75451), [@liggitt](https://github.com/liggitt))

    client.networkInterceptors().add(loggingInterceptor);
    ```

    **Warning:** Avoid `Level.HEADERS` and `Level.BODY` in production because
    they could leak passwords and other authentication credentials to insecure
    logs.

 *  **WebSocket API now uses `RequestBody` and `ResponseBody` for messages.**
    This is a backwards-incompatible API change.

    This increases the likelihood that HTTP/2 connections will be shared.
 *  New: Authentication challenges and credentials now use a charset. Use this in
    your authenticator to support user names and passwords with non-ASCII
    characters.
 *  New: Accept a charset in `FormBody.Builder`. Previously form bodies were
    always UTF-8.
 *  New: Support the `immutable` cache-control directive.

- The certificate signer no longer accepts ca.key passwords via the `CFSSL_CA_PK_PASSWORD` environment variable. This capability was not prompted by user request, never advertised, and recommended against in the security audit. ([#84677](https://github.com/kubernetes/kubernetes/pull/84677), [@mikedanese]...

* Support graceful termination in kube-dns ([#31894](https://github.com/kubernetes/kubernetes/pull/31894), [@MrHohn](https://github.com/MrHohn))
* When prompting for passwords, don't echo to the terminal ([#31586](https://github.com/kubernetes/kubernetes/pull/31586), [@brendandburns](https://github.com/brendandburns))
