# IBM Cloud HPCS Router add-on change log
{: #hpcs-router-changelog}

View information for version updates to the IBM Cloud HPCS Router add-on.
{: shortdesc}

* **Patch updates**: IBM Cloud keeps all your add-on components up-to-date by automatically rolling out patch updates to the most recent version of the HPCS Router that is offered by Red Hat OpenShift on IBM Cloud.
* **Minor version updates**: The minor version of the HPCS Router add-on matches the minor version of your Red Hat OpenShift cluster. In the CLI, you can run `ibmcloud oc cluster addon ls -c <cluster_name_or_ID>` to check the current version of your add-on, and `ibmcloud oc cluster get -c <cluster_name_or_ID>` to check the current version of your cluster.

To view a list of add-ons and the supported Red Hat OpenShift versions, see the [supported add-on versions table](https://cloud.ibm.com/docs/openshift?topic=openshift-supported-cluster-addon-versions&format=markdown) or run the following command.
