//
  // For example:
  // 'pods' means pods.
  // 'pods/log' means the log subresource of pods.
  // '*' means all resources, but not subresources.
  // 'pods/*' means all subresources of pods.
  // '*/scale' means all scale subresources.
  // '*/*' means all resources and their subresources.
  //
  // If wildcard is present, the validation rule will ensure resources do not
  // overlap with each other.

#### Endpoints

Endpoints have an optimized code path, as they are by far the most frequently updated resource - in a steady cluster, this will often be the *only* change, caused by scale up/down.

As a result, they do not go through `PushContext`, and changes do not trigger a `PushContext` recomputation. Instead, the current state is incrementally computed based on events from `ServiceDiscovery`.

#### Conclusion

* The ability to use kubectl scale jobs is deprecated. All other scale operations remain in place, but the ability to scale jobs will be removed in a future release.  ([#60139](https://github.com/kubernetes/kubernetes/pull/60139), [@soltysh](https://github.com/soltysh))

    *   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))

### Autoscaling

- Horizontal Pod Autoscaling can now scale targets up even when one or more metrics are invalid/unavailable, as long as one metric indicates a scale up should occur. ([#78503](https://github.com/kubernetes/kubernetes/pull/78503), [@gjtempleton](https://github.com/gjtempleton))

  without risking breaking old clients, such as controllers.

- `kubectl delete` no longer scales down workload API objects before deletion.
  Users who depend on ordered termination for the Pods of their StatefulSets
  must use `kubectl scale` to scale down the StatefulSet before deletion.

- `kubectl run --env` no longer supports CSV parsing. To provide multiple environment

      * If you passed a value to the `loss_scale` argument (the second argument) of `Policy`:

* [GCE] Enable by default audit logging truncating backend. ([#68342](https://github.com/kubernetes/kubernetes/pull/68342), [@loburm](https://github.com/loburm))
* [fluentd-gcp-scaler addon] Bump fluentd-gcp-scaler to 0.4 to pick up security fixes. ([#67691](https://github.com/kubernetes/kubernetes/pull/67691), [@loburm](https://github.com/loburm))

- If we set SelectPolicy MinPolicySelect on scaleUp behavior or scaleDown behavior,Horizontal Pod Autoscaler doesn't automatically scale the number of pods correctly ([#95647](https://github.com/kubernetes/kubernetes/pull/95647), [@JoshuaAndrew](https://github.com/JoshuaAndrew)) [SIG Apps and Autoscaling]
