## Changelog since v1.8.1

### Other notable changes

* Allow for configuring etcd hostname in the manifest ([#54403](https://github.com/kubernetes/kubernetes/pull/54403), [@wojtek-t](https://github.com/wojtek-t))
* Allow standard flags in client-gen. ([#53999](https://github.com/kubernetes/kubernetes/pull/53999), [@sttts](https://github.com/sttts))

 *  Fix: Don't crash with a `NullPointerException` if a server sends a close while we're sending a
