- Fix kube-apiserver not to create default/kubernetes service endpoints before it reports readiness via the /healthz and therefore is ready to serve requests. Also early during startup old endpoints are remove which might be left over from a previously crashed kube-apiserver. ([#74668](https://github.com/kubernetes/kubernetes/pull/74668),...

Kubernetes environment, there is a compatibility issue with certain virtualization products. Specifically the Windows version of the kubelet.exe calls `GetPhysicallyInstalledSystemMemory` to get the physical memory installed on Windows machines and reports it as part of node metrics to heapster. This API call fails for VMware and VirtualBox virtualization environments. This issue is not present in bare metal Windows deployments, in Hyper-V, or on some of the popular public cloud providers.

- The `kubelet` now reports distinguishes log messages about certificate rotation for its client cert and server cert separately to make debugging problems with one or the other easier.

## New Features

- kubelet: When node lease feature is enabled, kubelet reports node status to api server only if there is some change or it didn't report over last report interval. ([#69753](https://github.com/kubernetes/kubernetes/pull/69753), [@wangzhen127](https://github.com/wangzhen127))

* The maximum number of images the Kubelet will report in the Node status can now be controlled via the Kubelet's `--node-status-max-images` flag. The default (50) remains the same. ([#64170](https://github.com/kubernetes/kubernetes/pull/64170), [@mtaufen](https://github.com/mtaufen))

- `kube-proxy` now reports its health more accurately in dual-stack clusters when there are problems with only one IP family. ([#118146](https://github.com/kubernetes/kubernetes/pull/118146), [@aroradaman](https://github.com/aroradaman))
