- Kubeadm: instead of passing the etcd flag --experimental-initial-corrupt-check, set the InitialCorruptCheck=true etcd feature gate, and instead of passing the --experimental-watch-progress-notify-interval flag, pass its graduated variant --watch-progress-notify-interval. ([#132838](https://github.com/kubernetes/kubernetes/pull/132838), [@AwesomePatrol](https://github.com/AwesomePatrol)) [SIG Cluster Lifecycle]

- `ElasticIndexedJob` is graduated to GA. ([#125751](https://github.com/kubernetes/kubernetes/pull/125751), [@ahg-g](https://github.com/ahg-g)) [SIG Apps and Testing]
- `pause`: Added a `-v` flag to the Windows variant of the pause binary, which
  prints the version of pause and exits. The Linux pause binary already has this flag. ([#125067](https://github.com/kubernetes/kubernetes/pull/125067), [@neolit123](https://github.com/neolit123))

Pruning is activated by setting `spec.preserveUnknownFields: false` in the CustomResourceDefinition. A future apiextensions.k8s.io/v1 variant of CRDs will enforce pruning.

Pruning requires that CRD developer provides complete, structural validation schemas, either at the top-level or for all versions of the CRD.
