- The "kubectl cp" command now supports path shortcuts (../) in remote paths. ([#65189](https://github.com/kubernetes/kubernetes/pull/65189), [@juanvallejo](https://github.com/juanvallejo))
- Fixed dry-run output in kubectl apply --prune ([#69344](https://github.com/kubernetes/kubernetes/pull/69344), [@zegl](https://github.com/zegl))

  - [stable] `kubectl apply` is now able to delete resources you no longer need with `--prune` ([kubernetes/features#128](https://github.com/kubernetes/enhancements/issues/128))

- `kubeadm`: will now use universal deserializer to decode static pod. ([#120549](https://github.com/kubernetes/kubernetes/pull/120549), [@pacoxu](https://github.com/pacoxu))
