- Added warning for dup ports update/patching in pod's container ports and service ports. ([#113245](https://github.com/kubernetes/kubernetes/pull/113245), [@pacoxu](https://github.com/pacoxu))

- 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
