* **[alpha]** The Horizontal Pod Autoscaler now supports drawing metrics through the API server aggregator.
* **[alpha]** The Horizontal Pod Autoscaler now supports scaling on multiple, custom metrics.
* Cluster Autoscaler publishes its status to kube-system/cluster-autoscaler-status ConfigMap.
* Cluster Autoscaler can continue operations while some nodes are broken or unready.
* Cluster Autoscaler respects Pod Disruption Budgets when removing a node.

- OpenAPI V2 will no longer publish aggregated API server OpenAPI for group versions that do not match the APIService specified group version. ([#123570](https://github.com/kubernetes/kubernetes/pull/123570), [@Jefftree](https://github.com/Jefftree))

- The pod phase lifecycle guarantees that terminal Pods, those whose states are Unready or Succeeded, can not regress and will have all container stopped. Hence, terminal Pods will never be reachable and should not publish their IP addresses on the Endpoints or EndpointSlices, independently of the Service TolerateUnready option.

- The beta `RootCAConfigMap` feature gate is enabled by default and causes kube-controller-manager to publish a "kube-root-ca.crt" ConfigMap to every namespace. This ConfigMap contains a CA bundle used for verifying connections to the kube-apiserver. ([#96197](https://github.com/kubernetes/kubernetes/pull/96197), [@zshihang](https://github.com/zshihang))...

* The v1.Service.PublishNotReadyAddresses field is added to notify DNS addons to publish the notReadyAddresses of Enpdoints. The "service.alpha.kubernetes.io/tolerate-unready-endpoints" annotation has been deprecated and will be removed when clients have sufficient time to consume the field.
