- Made `kubectl-convert` binary linking static (also affects the deb and rpm packages). ([#114228](https://github.com/kubernetes/kubernetes/pull/114228), [@saschagrunert](https://github.com/saschagrunert))
- Migrated controller helper functions to use contextual logging. ([#115049](https://github.com/kubernetes/kubernetes/pull/115049), [@fatsheep9146](https://github.com/fatsheep9146))

- When using `kubectl replace` (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for `.spec.clusterIP` and `.spec.ports[].nodePort`.  Instead the API server will automatically carry these forward from the original object when the new object does not...

* Fix charms leaving services running after remove-unit ([#48446](https://github.com/kubernetes/kubernetes/pull/48446), [@Cynerva](https://github.com/Cynerva))
* Added helper funcs to schedulercache.Resource. ([#46926](https://github.com/kubernetes/kubernetes/pull/46926), [@k82cn](https://github.com/k82cn))

- Fix an issue with toleration merging & whitelist checking in the PodTolerationRestriction admission controller. ([#81732](https://github.com/kubernetes/kubernetes/pull/81732), [@tallclair](https://github.com/tallclair))
- Add a helper function to decode scheduler plugin args. ([#80696](https://github.com/kubernetes/kubernetes/pull/80696), [@hex108](https://github.com/hex108))

up flag handling in component-base/logs: that package no longer adds flags to the global flag sets. Commands which want the klog and `--log-flush-frequency` flags must explicitly call `logs.AddFlags`; the new `cli.Run` does that for commands. That helper function also covers flag normalization and printing of usage and errors in a consistent way (print usage text first if parsing failed, then the error).

### Contextual Logging in Alpha

Kubernetes 1.24 has introduced [contextual logging](https://github.com/kubernetes/enhancements/issues/3077)
that enables the caller of a function to control all aspects of logging (output formatting, verbosity, additional values and names).
