- Ingress:
  - `spec.ingressClassName` replaces the deprecated `kubernetes.io/ingress.class` annotation, and allows associating an Ingress object with a particular controller.

## Known Issues for v1.6.5

* If you use the [GLBC Ingress Controller](https://github.com/kubernetes/ingress-nginx/tree/0.9.0-beta.1/controllers/gce),
  upgrading an existing pre-v1.6.4 cluster to Kubernetes v1.6.5 will cause an unintentional
  [overwrite of manual edits to GCP Health Checks](https://github.com/kubernetes/ingress/issues/842)
  managed by the GLBC Ingress Controller. This can cause the health checks to start failing,

- Resolves flakes in the Ingress conformance tests due to conflicts with controllers updating the Ingress object ([#98430](https://github.com/kubernetes/kubernetes/pull/98430), [@liggitt](https://github.com/liggitt)) [SIG Network and Testing]

## Dependencies

### Added

* Due to an issue in ingress-gce controller in 1.10.0, creating multi-cluster ingresses with [kubemci CLI](https://github.com/GoogleCloudPlatform/k8s-multicluster-ingress) fails. This will be fixed in 1.10.1 release. ([GoogleCloudPlatform/k8s-multicluster-ingress#175](https://github.com/GoogleCloudPlatform/k8s-multicluster-ingress/issues/175))

- Kubectl-convert: Fix `no kind "Ingress" is registered for version` error ([#97754](https://github.com/kubernetes/kubernetes/pull/97754), [@wzshiming](https://github.com/wzshiming))

### 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))

* kubernetes-worker juju charm: Added support for setting the --enable-ssl-chain-completion option on the ingress proxy.  "action required": if your installation relies on supplying incomplete certificate chains and using OCSP to fill them in, you must set "ingress-ssl-chain-completion" to "true" in your juju configuration.
