#### Continuous Improvement
- Project sustainability is not just about features. Many SIGs have been working on  improving test coverage, ensuring the basics stay reliable, and stability of the core feature set and working on maturing existing features and cleaning up the backlog.

#### Extensibility

  * Advanced scheduling can be performed with [taints and tolerations](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#taints-and-tolerations-beta-feature)

* Various storage features have graduated to GA:
  * StorageClass pre-installed and set as default on Azure, AWS, GCE, OpenStack, and vSphere
