- Added `kubectl node drain` helper callbacks `OnPodDeletionOrEvictionStarted`
  and `OnPodDeletionOrEvictionFailed`; people extending `kubectl` can use these
  new callbacks for more granularity. Deprecated the `OnPodDeletedOrEvicted`

- 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))

For arrays or strings, the indices are <i>in range</i> if
<code>0</code> &lt;= <code>low</code> &lt;= <code>high</code> &lt;= <code>len(a)</code>,
otherwise they are <i>out of range</i>.
For slices, the upper index bound is the slice capacity <code>cap(a)</code> rather than the length.
A <a href="#Constants">constant</a> index must be non-negative and
<a href="#Representability">representable</a> by a value of type

    - `apiserver_flowcontrol_lower_limit_seats`: Configured lower bound on number of execution seats available to each priority level
    - `apiserver_flowcontrol_upper_limit_seats`: Configured upper bound on number of execution seats available to each priority level

- Added new k8s.io/component-helpers repository providing shared helper code for (core) components. ([#92507](https://github.com/kubernetes/kubernetes/pull/92507), [@ingvagabund](https://github.com/ingvagabund)) [SIG Apps, Node, Release and Scheduling]

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).

- 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))

- client-go: The `rest.AnonymousClientConfig(*rest.Config) *rest.Config` helper method no longer copies custom `Transport` and `WrapTransport` fields, because those can be used to inject user credentials.
