+# Changelog
+
+### 0.4.0
+
+* [54](https://github.com/nginxinc/kubernetes-ingress/pull/54): Previously, when specifying the port of a service in an Ingress rule, you had to use the value of the target port of that port of the service, which was incorrect. Now you must use the port value or the name of the port of the service instead of the target port value. **Note**: Please make necessary changes to your Ingress resources, if ports of your services have different values of the port and the target port fields.
+* [55](https://github.com/nginxinc/kubernetes-ingress/pull/55): Add support for the `kubernetes.io/ingress.class` annotation in Ingress resources.
+* [58](https://github.com/nginxinc/kubernetes-ingress/pull/58): Add the version information to the controller. For each version of the NGINX controller, you can find a corresponding image on [DockerHub](https://hub.docker.com/r/nginxdemos/nginx-ingress/tags/) with a tag equal to the version. The latest version is available through the `latest` tag.
+
+The previous version was 0.3
+
+
+### Notes
+
+* Except when mentioned otherwise, the controller refers both to the NGINX and the NGINX Plus Ingress controllers.
