+### {{% icon download %}} Upgrade
+
+- For NGINX, use the 5.3.1 images from our [DockerHub](https://hub.docker.com/r/nginx/nginx-ingress/tags?page=1&ordering=last_updated&name=5.3.1), [GitHub Container](https://github.com/nginx/kubernetes-ingress/pkgs/container/kubernetes-ingress), [Amazon ECR Public Gallery](https://gallery.ecr.aws/nginx/nginx-ingress) or [Quay.io](https://quay.io/repository/nginx/nginx-ingress).
+- For NGINX Plus, use the 5.3.1 images from the F5 Container registry or build your own image using the 5.3.1 source code.
+- For Helm, use version 2.4.1 of the chart.
+- For users making use of a custom `oidc.conf` by following this [guide]({{< ref "/nic/tutorials/oidc-custom-configuration.md" >}}), in this release this behaviour has changed from a static file (`oidc.conf`) to a dynamic template (`oidc.tmpl`).  The [guide]({{< ref "/nic/tutorials/oidc-custom-configuration.md" >}}) has been updated to reflect the recent changes.  If you still require a custom OIDC configuration, you should copy all the modifications you have made prior to 5.3.0 to the `oidc.tmpl` in the `ConfigMap`.
