### Introducing Windows CSI support alpha for Kubernetes

With the release of Kubernetes 1.18, an alpha version of CSI Proxy for Windows is getting released. CSI proxy enables non-privileged (pre-approved) containers to perform privileged storage operations on Windows. CSI drivers can now be supported in Windows by leveraging CSI proxy.

- **Cluster Lifecycle**
  - [alpha] Improved UX and usability for the kubeadm binary that makes it easy to get a new cluster running. ([docs](http://kubernetes.io/docs/getting-started-guides/kubeadm/)) ([changelog](https://github.com/kubernetes/kubeadm/blob/master/CHANGELOG.md)) ([kubernetes/features#11](https://github.com/kubernetes/enhancements/issues/11))
- **Cluster Ops**
