### API Change

- Fixes a regression in openapi descriptions of PodIP.IP  and HostIP.IP fields to mark the fields used as keys in those lists as required. ([#126666](https://github.com/kubernetes/kubernetes/pull/126666), [@thockin](https://github.com/thockin)) [SIG API Machinery]

### Feature

- Kubernetes is now built with go 1.22.6 ([#126970](https://github.com/kubernetes/kubernetes/pull/126970), [@cpanato](https://github.com/cpanato)) [SIG Release and Testing]

* The annotation `service.alpha.kubernetes.io/tolerate-unready-endpoints` is deprecated.  Users should use Service.spec.publishNotReadyAddresses instead. ([#63742](https://github.com/kubernetes/kubernetes/pull/63742), [@thockin](https://github.com/thockin))

   * uncommon to specify {@code concurrencyLevel(1)} in order to achieve more deterministic eviction
   * behavior.
   *
   * <p>Note that future implementations may abandon segment locking in favor of more advanced
   * concurrency controls.
   *
   * @return this {@code CacheBuilder} instance (for chaining)
   * @throws IllegalArgumentException if {@code concurrencyLevel} is nonpositive

* Services of type=LoadBalancer which have no endpoints will now immediately ICMP reject connections, rather than time out. ([#74394](https://github.com/kubernetes/kubernetes/pull/74394), [@thockin](https://github.com/thockin))
* Ensure Azure load balancer cleaned up on 404 or 403 when deleting LoadBalancer services. ([#75256](https://github.com/kubernetes/kubernetes/pull/75256), [@feiskyer](https://github.com/feiskyer))
