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 at v1.32 with `matchLabelKeys` are scheduled before reaching v1.34. Controllers relying on `matchLabelKeys` no longer need to handle them directly and can use `labelSelector` instead. The new feature gate `MatchLabelKeysInPodTopo...
