* A cluster-autoscaler ClusterRole is added to cover only the functionality required by Cluster Autoscaler and avoid abusing system:cluster-admin role. ([#64503](https://github.com/kubernetes/kubernetes/pull/64503), [@kgolab](https://github.com/kgolab))

setting the `UnauthenticatedHTTP2DOSMitigation` feature gate to `true` (it is disabled by default). An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose not to enable the kube-apiserver mitigation to avoid disrupting load balancer → kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may choose not to enable the kube-apiserver mitigation to prevent performance regressions...

- When feature gate `JobTrackingWithFinalizers` is enabled:
  - Limit the number of Pods tracked in a single Job sync to avoid starvation of small Jobs.
