UPGRADE:

• For NGINX, use the 1.6.0 image from our DockerHub: nginx/nginx-ingress:1.6.0 or nginx/nginx-ingress:1.6.0-alpine
• For NGINX Plus, please build your own image using the 1.6.0 source code.
• For Helm, use version 0.4.0 of the chart.

HELM UPGRADE:

If leader election (the controller.reportIngressStatus.enableLeaderElection parameter) is enabled, when upgrading to the new version of the Helm chart:

1. Make sure to specify a new ConfigMap lock name (controller.reportIngressStatus.leaderElectionLockName) different from the one that was created by the current version. To find out the current name, check ConfigMap resources in the namespace where the Ingress Controller is running.
2. After the upgrade, delete the old ConfigMap.

Otherwise, the helm upgrade will not succeed.
