## Changelog since v1.11.8

### Other notable changes

* Prevent AWS Network Load Balancer security groups ingress rules to be deleted by ensuring target groups are tagged. ([#73594](https://github.com/kubernetes/kubernetes/pull/73594), [@masterzen](https://github.com/masterzen))

     * works for ASCII. So for now, assume any non-ASCII characters are valid. The only place this
     * seems to be documented is here:
     * https://groups.google.com/d/topic/google-web-toolkit-contributors/1UEzsryq1XI
     *
     * <p>ASCII characters in the part are expected to be valid per RFC 1035, with underscore also
     * being allowed due to widespread practice.
     */

- Fix handling of aws-load-balancer-security-groups annotation. Security-Groups assigned with this annotation are no longer modified by kubernetes which is the expected behaviour of most users. Also no unnecessary Security-Groups are created anymore if this annotation is used. ([#88689](https://github.com/kubernetes/kubernetes/pull/88689), [@Elias481](https://github.com/Elias481)) [SIG...

* The kube-apiserver discovery APIs (for example, `/apis`) return information about the API groups being served, and can change dynamically.
During server startup, prior to the server reporting healthy (via `/healthz`), not all API groups may be reported.
Wait for the server to report healthy (via `/healthz`) before depending on the information provided by the discovery APIs.

## Highlights

* Authorization:
  * **Alpha** RBAC authorization API group
* Federation
  * federation api group is now **beta**
  * Services from all federated clusters are now registered in Cloud DNS (AWS and GCP).
* Stateful Apps:
  * **alpha** PetSets manage stateful apps

* kube-apiserver: `--runtime-config` can once again be used to enable/disable serving specific resources in the `extensions/v1beta1` API group. Note that specific resource enablement/disablement is only allowed for the `extensions/v1beta1` API group for legacy reasons. Attempts to enable/disable individual resources in other API groups will print a warning, and will return an error in future releases.
