- Azure VMSS LoadBalancerBackendAddressPools updating has been improved with sequential-sync + concurrent-async requests. ([#88699](https://github.com/kubernetes/kubernetes/pull/88699), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

* Bump Heapster to v1.5.2 ([#61396](https://github.com/kubernetes/kubernetes/pull/61396), [@kawych](https://github.com/kawych))
* Fixed a race condition in k8s.io/client-go/tools/cache.SharedInformer that could violate the sequential delivery guarantee and cause panics on shutdown. ([#59828](https://github.com/kubernetes/kubernetes/pull/59828), [@krousey](https://github.com/krousey))
