- Graduated support for `minDomains` in pod topology spread constraints, to general availability.
  The `MinDomainsInPodTopologySpread` feature gate no longer has any effect, and the field is

- New parameter `defaultingType` for `PodTopologySpread` plugin allows to use k8s defined or user provided default constraints ([#95048](https://github.com/kubernetes/kubernetes/pull/95048), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- Revised the logic for DaemonSet rolling update to exclude nodes if scheduling constraints are not met.

  matching the spreading selector on those excluded nodes (not matching the node affinity/selector),
  especially when the `topologyKey` is not node-level. Revisit the node affinity and/or pod selector in the
  topology spread constraints to avoid this scenario. ([#107009](https://github.com/kubernetes/kubernetes/pull/107009), [@kerthcet](https://github.com/kerthcet))

multiple clusters ensures that cluster-level autoscalers are
consistently deployed across those clusters, and dynamically managed
to ensure that autoscaling can occur optimially in all clusters,
within a set of global constraints on the total number of replicas
permitted across all clusters.  If replicas are not
required in some clusters due to low system load or insufficient quota
or capacity in those clusters, additional replicas are made available
