- Fixes a bug where Services using finalizers may hold onto ClusterIP and/or NodePort allocated resources for longer than expected if the finalizer is removed using the status subresource ([#120655](https://github.com/kubernetes/kubernetes/pull/120655), [@aojea](https://github.com/aojea)) [SIG Network and Testing]...

- 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

- KEP-1880: Users of the new feature to add multiple service CIDR will use by default a dual-write strategy on the new ClusterIP allocators to avoid the problem of possible duplicate IPs allocated to Services when running skewed kube-apiservers using different allocators. They can opt-out of this behavior by enabled the feature gate DisableAllocatorDualWrite. ([#122047](h...

A Service `ClusterIP` can be assigned:

* dynamically, which means the cluster will automatically pick a free IP within the configured Service IP range.
* statically, which means the user will set one IP within the configured Service IP range.

Service `ClusterIP` are unique, hence, trying to create a Service with a `ClusterIP` that has already been allocated will return an error.

- 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.

- kube-proxy uses field-selector clusterIP!=None on Services to avoid watching for Headless Services, reducing unnecessary network bandwidth ([#126769](https://github.com/kubernetes/kubernetes/pull/126769), [@Sakuralbj](https://github.com/Sakuralbj)) [SIG Network]
