- `kubeadm.k8s.io/v1beta2` has been deprecated and will be removed in a future release, possibly in 3 releases (one year). You should start using `kubeadm.k8s.io/v1beta3` for new clusters. To migrate your old configuration files on disk you can use the `kubeadm config migrate` command. ([#107013](https://github.com/kubernetes/kubernetes/pull/107013), [@pacoxu](https://github.com/pacoxu))

- Added `--output plaintext-openapiv2` argument to kubectl explain to use old openapiv2 `explain` implementation. ([#115480](https://github.com/kubernetes/kubernetes/pull/115480), [@alexzielenski](https://github.com/alexzielenski))

- Windows Kubeproxy will use the update load balancer API for load balancer updates, instead of the previous delete and create APIs.

- Fix the bug PIP's DNS is deleted if no DNS label service annotation isn't set. ([#87311](https://github.com/kubernetes/kubernetes/pull/87311), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Fix: set nil cache entry based on old cache ([#87592](https://github.com/kubernetes/kubernetes/pull/87592), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

### Bug or Regression

- Ensure daemonset controller to count old unhealthy pods towards max unavailable budget ([#127774](https://github.com/kubernetes/kubernetes/pull/127774), [@ncdc](https://github.com/ncdc)) [SIG Apps]

- The `PreferSameZone` and `PreferSameNode` values for Service's
  `trafficDistribution` field are now GA. The old value `PreferClose` is now

            async with nested_context(app) as maybe_nested_state:
                if maybe_nested_state is None and maybe_original_state is None:
                    yield None  # old ASGI compatibility
                else:
                    yield {**(maybe_nested_state or {}), **(maybe_original_state or {})}

    return merged_lifespan  # type: ignore[return-value]

For stable features, the `kubectl` tool follows the Kubernetes [version skew policy](https://kubernetes.io/releases/version-skew-policy/);
however, kubectl v1.21 and older do not support the new API for ephemeral containers.

## Changelog since v1.12.4
