 Azure Red Hat OpenShift receives improvements on an ongoing basis. To stay up to date with the most recent developments, this article provides you with information about the latest releases.
 
+## Update - September 2023

+To create a private cluster without a public IP address, you can now add the parameter `--outbound-type UserDefinedRouting` to the `aro create` command. See [Create a private cluster without a public IP address](howto-create-private-cluster-4x.md#create-a-private-cluster-without-a-public-ip-address) for details.
+
+A cluster that is deployed with this feature and is running version 4.11 or higher can be scaled to 120 nodes and 30,000 pods.

+          Azure Red Hat OpenShift 4.x has a 250 pod-per-node limit and a 60 compute node limit. These limits cap the maximum number of pods supported in a cluster to 250×60 = 15,000. If the cluster is created using User Defined Routing (UDR) and runs version 4.11 or higher, the limits are 120 compute nodes and 30,000 pods.
           
       - question: Can a cluster have compute nodes across multiple Azure regions?
         answer: No. All nodes in an Azure Red Hat OpenShift cluster must originate in the same Azure region.
