* clusters. When that var is set to true, the command line flag enabling kubelet
    * client certificate rotation will be added to the kubelet command line.
* Make sure that resources being updated are handled correctly by Quota system ([#52452](https://github.com/kubernetes/kubernetes/pull/52452), [@gnufied](https://github.com/gnufied))

- Added a new command line argument `--interactive` to kubectl. The new command line argument lets a user confirm deletion requests per resource interactively. ([#114530](https://github.com/kubernetes/kubernetes/pull/114530), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI and Testing]

- Metrics Server image bumped to v0.5.2 ([#106492](https://github.com/kubernetes/kubernetes/pull/106492), [@serathius](https://github.com/serathius))
- 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))

### Other (Cleanup or Flake)

- Introduced a feature gate mechanism to `client-go`. Depending on the actual implementation, users can control features via environmental variables or command line options. ([#122555](https://github.com/kubernetes/kubernetes/pull/122555), [@p0lyn0mial](https://github.com/p0lyn0mial))

- For `kubectl`, `--server-side` now migrates ownership of all fields used by client-side-apply to the specified `--fieldmanager`. This prevents fields previously specified using kubectl from being able to live outside of server-side-apply's management and become undeleteable.
