- `kubectl auth reconcile` now outputs details about what changes are being made ([#71564](https://github.com/kubernetes/kubernetes/pull/71564), [@liggitt](https://github.com/liggitt))

* Fix dry-run output in kubectl apply --prune ([#69344](https://github.com/kubernetes/kubernetes/pull/69344), [@zegl](https://github.com/zegl))
* kubectl run now generates apps/v1 deployments by default ([#71006](https://github.com/kubernetes/kubernetes/pull/71006), [@liggitt](https://github.com/liggitt))

*   Added --dry-run option to kubectl drain. ([#52440](https://github.com/kubernetes/kubernetes/pull/52440),[ @juanvallejo](https://github.com/juanvallejo))
*   Kubectl now outputs <none> for columns specified by -o custom-columns but not found in object, rather than "xxx is not found" ([#51750](https://github.com/kubernetes/kubernetes/pull/51750),[ @jianhuiz](https://github.com/jianhuiz))

    to be resolved considering this now builds.
  
  - make kube::util::find-binary not dependent on bazel-out/ structure
  
    Implement an aspect that outputs go_build_mode metadata for go binaries,

- In the `kubectl describe` output, the fields with names containing special characters are now displayed as-is without any pretty formatting, avoiding awkward outputs.  ([#75483](https://github.com/kubernetes/kubernetes/pull/75483), [@gsadhani](https://github.com/gsadhani))

- Kubeadm: add a new `output/v1alpha2` API that is identical to the `output/v1alpha1`, but attempts to resolve some internal dependencies with the `kubeadm/v1beta2` API. The `output/v1alpha1` API is now deprecated and will be removed in a future release. ([#105295](https://github.com/kubernetes/kubernetes/pull/105295), [@neolit123](https://github.com/neolit123))...

- Kube-log-runner: Added the `-log-file-size` parameter to rotate log output into a new file once it reached a certain size. Introduced `-log-file-age` to enable automatic removal of old output files, and `-flush-interval` to support periodic flushing.

### Other (Cleanup or Flake)

- Added a short output format argument for `kubectl explain`. You could now use `-o` as an abbreviation for `--output` in commands such as `kubectl explain <resource> --output plaintext-openapiv2`. ([#127869](https://github.com/kubernetes/kubernetes/pull/127869), [@ak20102763](https://github.com/ak20102763))

- kubeadm: Added support for machine-readable output with `-o yaml` and `-o json` to the command `kubeadm certs check-expiration`. This change is introduced in a new API: ``` kind: CertificateExpirationInfo apiVersion: output.kubeadm.k8s.io/v1alpha3 ``` The existing non-structured formatting is preserved. The output API version v1alpha2 is now deprecated and will be removed in a future release. Please migrate to using v1alpha3.

- Kubeadm: Some text in the `kubeadm upgrade plan` output has changed. If you have scripts or other automation that parses this output, please review these changes and update your scripts to account for the new output.
