* Beta annotations `service.beta.kubernetes.io/external-traffic` and `service.beta.kubernetes.io/healthcheck-nodeport` have been removed. Please use fields `service.spec.externalTrafficPolicy` and `service.spec.healthCheckNodePort` instead. ([#50224](https://github.com/kubernetes/kubernetes/pull/50224), [@xiangpengzhao](https://github.com/xiangpengzhao))

- When using `kubectl replace` (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for `.spec.clusterIP` and `.spec.ports[].nodePort`.  Instead the API server will automatically carry these forward from the original object when the new object does not specify them. ([#104672](https://github.com/kubernetes/kubernetes/pull/104672), [@thockin](https://github.com/thockin)) [SIG Network]...

* Allow services which use same port, different protocol to use the same nodePort for both ([#30253](https://github.com/kubernetes/kubernetes/pull/30253), [@AdoHe](https://github.com/AdoHe))

* You can now have services that listen on the same host ports on different interfaces by specifying `--nodeport-addresses`. ([#62003](https://github.com/kubernetes/kubernetes/pull/62003), [@m1093782566](https://github.com/m1093782566))
* Added port-forward examples for service
