`unschedulableAndUnresolvable` status in `PostFilter`. ([#114699](https://github.com/kubernetes/kubernetes/pull/114699), [@kerthcet](https://github.com/kerthcet))

- Added the --dns-loop-detect option to dnsmasq, which is run by kube-dns. ([#67302](https://github.com/kubernetes/kubernetes/pull/67302), [@dixudx](https://github.com/dixudx))
- Kubernetes now supports extra `--prune-whitelist` resources in kube-addon-manager. ([#67743](https://github.com/kubernetes/kubernetes/pull/67743), [@Random-Liu](https://github.com/Random-Liu))

- Restore the ability to `kubectl apply --prune` without --namespace flag.  Since 1.17, `kubectl apply --prune` only prunes resources in the default namespace (or from kubeconfig) or explicitly specified in command line flag.  But this is s breaking change from kubectl 1.16, which can prune resources in all namespace in config file.  This patch restores the kubectl 1.16 behaviour. ([#89551](https://github.com/kube...

- Added more message for no PodSandbox container. ([#107116](https://github.com/kubernetes/kubernetes/pull/107116), [@yxxhero](https://github.com/yxxhero))
- Added prune flag into `diff` command to simulate `apply --prune`. ([#105164](https://github.com/kubernetes/kubernetes/pull/105164), [@ardaguclu](https://github.com/ardaguclu))

- 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))

* `kubectl apply --prune` now uses the apps/v1 API to prune workload resources ([#72352](https://github.com/kubernetes/kubernetes/pull/72352), [@liggitt](https://github.com/liggitt))

- `kubeadm`: will now use universal deserializer to decode static pod. ([#120549](https://github.com/kubernetes/kubernetes/pull/120549), [@pacoxu](https://github.com/pacoxu))
- `kubectl prune v2`: Switched annotation from `contains-group-resources` to `contains-group-kinds`,
  because this is what we defined in the KEP and is clearer to end-users. Although the functionality is

  - [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))
