- Improve CPU sample sanitization in HPA by taking metric's freshness into account. ([#68068](https://github.com/kubernetes/kubernetes/pull/68068), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))

  * Flex volume driver deployment is simplified in the following ways:

    * New driver files can now be automatically discovered and initialized without requiring a kubelet or controller-manager restart.

    * A sample DaemonSet to deploy Flexvolume drivers is now available.

* [prototype] Volume snapshots

  * You can now create a volume snapshot by calling the Kubernetes API.

- The sample-apiserver aggregated conformance test has updated to use the Kubernetes v1.17.0 sample apiserver ([#84735](https://github.com/kubernetes/kubernetes/pull/84735), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Architecture, CLI and Testing]

- Projects which use k8s.io/code-generator and invoke `generate-groups` or `generate-internal-groups.sh` have a new, simpler script (`kube_codegen.sh`) they can use.  The old scripts are deprecated but remain intact. ([#117262](https://github.com/kubernetes/kubernetes/pull/117262), [@thockin](https://github.com/thockin)) [SIG API Machinery and Instrumentation]

- Bump addon-resizer to 1.8.7 to fix issues with using deprecated extensions APIs ([#85864](https://github.com/kubernetes/kubernetes/pull/85864), [@liggitt](https://github.com/liggitt))
