* [GCP kube-up.sh] Variables that were part of kube-env that were only used for kubelet flags are no longer being set, and are being replaced by the more portable mechanism of the kubelet configuration file. The individual variables in the kube-env metadata entry were never meant to be a stable interface and this release note only applies if you are depending on them. ([#60020](https://github.com/kubernet...

- Added namespace autocompletion for `kubectl config set-context` command. ([#124994](https://github.com/kubernetes/kubernetes/pull/124994), [@TessaIO](https://github.com/TessaIO)) [SIG CLI]

### Promoted endPort in Network Policy to Stable

Promoted `endPort` in [Network Policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/#targeting-a-range-of-ports) to GA. Network Policy providers that support `endPort` field now can use it to specify a range of ports to apply a Network Policy. Previously, each Network Policy could only target a single port.

* Fix AWS NLB security group updates where valid security group ports were incorrectly removed ([#68422](https://github.com/kubernetes/kubernetes/pull/68422), [@kellycampbell](https://github.com/kellycampbell))
    * when updating a service or when node changes occur.

- 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.
