API group): The Horizontal Pod Autoscaling feature now supports custom metrics
(Alpha), allowing you to specify application-level metrics and thresholds to
trigger scaling up and down the number of pods in your application.

functionality found in the CLI as a more approachable and discoverable way of

  // Example: when this is set to 30%, the old RC can be scaled down to 70% of desired pods
  // immediately when the rolling update starts. Once new pods are ready, old RC
  // can be scaled down further, followed by scaling up the new RC, ensuring
  // that the total number of pods available at all times during the update is at
  // least 70% of desired pods.

* StatefulSets now include an alpha scaling feature accessible by setting the `spec.podManagementPolicy` field to `Parallel`.  The controller will not wait for pods to be ready before adding the other pods, and will replace deleted pods as needed.  Since parallel scaling creates pods out of order, you cannot depend on predictable membership changes within your set. ([#44899](https://github.com/kuberne...
