- The Kubernetes API server merged selectors built from `matchLabelKeys` into the `labelSelector` of `topologySpreadConstraints`, aligning Pod Topology Spread behavior with Inter-Pod Affinity. To prevent breaking existing Pods using `matchLabelKeys`, this scheduler behavior was preserved until v1.34. Upgrades from v1.32 to v1.34 should be done incrementally (v1.32 → v1.33 → v1.34), ensuring Pods created...

- Pod spread constraints have been added in alpha. You can use these constraints to control how Pods are spread across the cluster among failure-domains. ([#77327](https://github.com/kubernetes/kubernetes/pull/77327), [#77760](https://github.com/kubernetes/kubernetes/pull/77760), [#77828](https://github.com/...

- The calculations for Pod topology spread skew now exclude nodes that
  don't match the node affinity/selector. This may lead to unschedulable pods if you previously had pods
  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

* Default behavior in Cinder storageclass is changed. If availability is not specified, the zone is chosen by algorithm. It makes possible to spread stateful pods across many zones. ([#44798](https://github.com/kubernetes/kubernetes/pull/44798), [@zetaab](https://github.com/zetaab))

- The `minDomains` field in Pod Topology Spread is graduated to beta ([#110388](https://github.com/kubernetes/kubernetes/pull/110388), [@sanposhiho](https://github.com/sanposhiho)) [SIG API Machinery and Apps]

- Added a one-time random duration of up to 50% of kubelet's `nodeStatusReportFrequency` to help spread the node status update load evenly over time. ([#128640](https://github.com/kubernetes/kubernetes/pull/128640), [@mengqiy](https://github.com/mengqiy))

- 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

- User can choose a different static policy option `SpreadPhysicalCPUsPreferredOption` to spread cpus across physical cpus for some specific applications ([#123733](https://github.com/kubernetes/kubernetes/pull/123733), [@Jeffwan](https://github.com/Jeffwan)) [SIG Node]

- Fix system default topology spreading when nodes don't have zone labels. Pods correctly spread by default now. ([#105046](https://github.com/kubernetes/kubernetes/pull/105046), [@alculquicondor](https://github.com/alculquicondor))

- The scheduler skips the `PodTopologySpread` Filter plugin if no spread constraints.
  It will affect some metrics values related to the `PodTopologySpread` Filter plugin. ([#117683](https://github.com/kubernetes/kubernetes/pull/117683), [@utam0k](https://github.com/utam0k))
