- Fixed a race condition between `Run()` and `SetTransform()` and `SetWatchErrorHandler()` in shared informers. ([#117870](https://github.com/kubernetes/kubernetes/pull/117870), [@howardjohn](https://github.com/howardjohn)) [SIG API Machinery]

* When creating a service with annotation: service.beta.kubernetes.io/load-balancer-source-ranges containing multiple source ranges and service.beta.kubernetes.io/azure-shared-securityrule: "false",  the NSG rules will be collapsed.
