- Kube-controller-manager: Fixes bug setting headless service labels on endpoints ([#85361](https://github.com/kubernetes/kubernetes/pull/85361), [@liggitt](https://github.com/liggitt))

* **[stable]** Volume plugin for ScaleIO enabling pods to seamlessly access and use data stored on Dell EMC ScaleIO volumes.

      * if all zones in the cluster are in "fullDisruption" state we stop all evictions.
* Add a flag for `kubectl expose`to set ClusterIP and allow headless services ([#28239](https://github.com/kubernetes/kubernetes/pull/28239), [@ApsOps](https://github.com/ApsOps))

# v1.16.3

[Documentation](https://docs.k8s.io)

- kube-proxy uses field-selector clusterIP!=None on Services to avoid watching for Headless Services, reducing unnecessary network bandwidth ([#126769](https://github.com/kubernetes/kubernetes/pull/126769), [@Sakuralbj](https://github.com/Sakuralbj)) [SIG Network]

- Added warnings when creating headless service with set `loadBalancerIP`,`externalIPs` and/or `SessionAffinity`. ([#132214](https://github.com/kubernetes/kubernetes/pull/132214), [@Peac36](https://github.com/Peac36))

- Adds `create ingress` command to `kubectl` ([#78153](https://github.com/kubernetes/kubernetes/pull/78153), [@amimof](https://github.com/amimof)) [SIG CLI and Network]
- Adds a headless service on node-local-cache addon. ([#88412](https://github.com/kubernetes/kubernetes/pull/88412), [@stafot](https://github.com/stafot)) [SIG Cloud Provider and Network]

- On single-stack configured (IPv4 or IPv6, but not both) clusters, Services which are both headless (no clusterIP) and selectorless (empty or undefined selector) will report `ipFamilyPolicy RequireDualStack` and will have entries in `ipFamilies[]` for both IPv4 and IPv6.  This is a change from alpha, but does not have any impact on the manually-specified...

- fixes a validation error that could prevent updates to StatefulSet objects containing non-normalized resource requests ([#66165](https://github.com/kubernetes/kubernetes/pull/66165), [@liggitt](https://github.com/liggitt))
- Headless Services with no ports defined will now create Endpoints correctly, and appear in DNS. ([#67622](https://github.com/kubernetes/kubernetes/pull/67622), [@thockin](https://github.com/thockin))
