- 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

* Cloud Controller Manager now sets Node.Spec.ProviderID ([#50730](https://github.com/kubernetes/kubernetes/pull/50730), [@andrewsykim](https://github.com/andrewsykim))

  the correct number of rules, rather than being off by one.
  
  Fixed multiple iptables proxy regressions introduced in 1.22:
  
    - When using Services with SessionAffinity, client affinity for an
      endpoint now gets broken when that endpoint becomes non-ready
      (rather than continuing until the endpoint is fully deleted).
  
    - Traffic to a service IP now starts getting rejected (as opposed to

- Pod Affinity/AntiAffinity label selectors are now validated in the pod affinity score plugin ([#93758](https://github.com/kubernetes/kubernetes/pull/93758), [@damemi](https://github.com/damemi)) [SIG Scheduling]

- Added feature support to Windows for configuring session affinity of Kubernetes services.
