on, set `--fail-swap-on=false`. The experimental flag `--experimental-fail-swap-on` is deprecated in this release, and will be removed in a future release.

* The `autoscaling/v2alpha1` API is now at `autoscaling/v2beta1`. However, the form of the API remains unchanged. Migrate the `HorizontalPodAutoscaler` resources to `autoscaling/v2beta1` to persist the `HorizontalPodAutoscaler` changes introduced in `autoscaling/v2alpha1`. The Horizontal Pod Autoscaler changes include support for...

### Feature

- Various controllers that write out IP address or CIDR values to API objects now
  ensure that they always write out the values in canonical form. ([#130101](https://github.com/kubernetes/kubernetes/pull/130101), [@danwinship](https://github.com/danwinship)) [SIG Apps, Network and Node]

- Changed `kubectl exec` syntax to require `--` before the command. The form `kubectl exec [POD] [COMMAND]` is no longer supported; use `kubectl exec [POD] -- [COMMAND]` instead. ([#133841](https://github.com/kubernetes/kubernetes/pull/133841), [@yangjunmyfm192085](https://github.com/yangjunmyfm192085))

- For `kubeadm`: support for custom imagetags for etcd images which contain build metadata, when imagetags are in the form of version_metadata. For instance, if the etcd version is v3.4.13+patch.0, the supported imagetag would be v3.4.13_patch.0 ([#100350](https://github.com/kubernetes/kubernetes/pull/100350), [@jr0d](https://github.com/jr0d))

* [GCP] Remove confusing error log entry form fluentd scalers. ([#72243](https://github.com/kubernetes/kubernetes/pull/72243), [@cezarygerard](https://github.com/cezarygerard))

* The `NodeRestriction` admission plugin limits the `Node` and `Pod` objects a kubelet can modify. In order to be limited by this admission plugin, kubelets must use credentials in the `system:nodes` group, with a username in the form `system:node:<nodeName>`. Such kubelets will only be allowed to modify their own `Node` API object, and only modify `Pod` API objects that are bound to their node. ([#45929](https://github.com/kubernetes/kubernetes/pull/45929), [@liggitt](https://...

    *   The view role includes read permissions on poddisruptionbudget.policy resources.
*   RBAC rules can now match the same subresource on any resource using the form `*/(subresource)`. For example, `*/scale` matches requests to `replicationcontroller/scale`. ([#53722](https://github.com/kubernetes/kubernetes/pull/53722),[ @deads2k](https://github.com/deads2k))

    * A distributed claim allows the OIDC provider to delegate a claim to a
    * separate URL.  Distributed claims are of the form as seen below, and are
    * defined in the OIDC Connect Core 1.0, section 5.6.2.
