- Service controller: only sync LB node pools when relevant fields in Node changes ([#90769](https://github.com/kubernetes/kubernetes/pull/90769), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
- Set CSIMigrationvSphere feature gates to beta.

- Fixed 1.31 regression that can crash kube-controller-manager's service-lb-controller loop. ([#128182](https://github.com/kubernetes/kubernetes/pull/128182), [@carlory](https://github.com/carlory)) [SIG API Machinery, Cloud Provider and Network]

- Azure: fix concurreny issue in lb creation ([#89604](https://github.com/kubernetes/kubernetes/pull/89604), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

- Fixes #115825. Kube-proxy will now include the `healthz` state in its response to the LB HC as to avoid indicating to the LB that it should use the node in question when Kube-proxy is not healthy.

  For example the exec/{podNamespace}/{podID}/{containerName} is now just exec. ([#87913](https://github.com/kubernetes/kubernetes/pull/87913), [@cheftako](https://github.com/cheftako)) [SIG Node]

    * If excludeMasterFromStandardLB is not set, it will be default to true, which means master nodes are excluded to the backend of standard LB.
    * Also note standard load balancer doesn't work with annotation `service.beta.kubernetes.io/azure-load-balancer-mode`. This is because all nodes (except master) are added as the LB backends.
