- The `kube-apiserver` will now expose four new metrics to inform about errors on the clusterIP and nodePort allocation logic. ([#120843](https://github.com/kubernetes/kubernetes/pull/120843), [@aojea](https://github.com/aojea))
- The `volume_zone` plugin will consider `beta` labels as `GA` labels during the scheduling

- Added new feature gate `ServiceNodePortStaticSubrange`, to enable the new strategy in the `NodePort` Service port allocators, so the node port range is subdivided and dynamic allocated `NodePort` port for Services are allocated preferentially from the upper range.

## Before Upgrading

* Exclude nodes labeled as master from LoadBalancer / NodePort; restores documented behaviour. ([#44745](https://github.com/kubernetes/kubernetes/pull/44745), [@justinsb](https://github.com/justinsb))

* Remove requirement that Endpoints IPs be IPv4 ([#23317](https://github.com/kubernetes/kubernetes/pull/23317), [@aanm](https://github.com/aanm))
* Fix unintended change of Service.spec.ports[].nodePort during kubectl apply ([#24180](https://github.com/kubernetes/kubernetes/pull/24180), [@AdoHe](https://github.com/AdoHe))

- Fixed azure disk translation issue due to lower case `managed` kind. ([#103439](https://github.com/kubernetes/kubernetes/pull/103439), [@andyzhangx](https://github.com/andyzhangx))
- Fixed client IP preservation for NodePort service with protocol SCTP in ipvs. ([#104756](https://github.com/kubernetes/kubernetes/pull/104756), [@tnqn](https://github.com/tnqn))

- Reduce kube-proxy CPU usage in IPVS mode when a large number of nodePort services exist. ([#79444](https://github.com/kubernetes/kubernetes/pull/79444), [@cezarsa](https://github.com/cezarsa))

- 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]...

* 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))

- Fix counting error in service/nodeport/loadbalancer quota check ([#97828](https://github.com/kubernetes/kubernetes/pull/97828), [@pacoxu](https://github.com/pacoxu)) [SIG API Machinery and Network]
