+* **Create additional security groups in {hcp-title} clusters.** Starting with ROSA CLI version 1.2.47, you can now create additional security groups using the ROSA CLI when creating {hcp-title} clusters. Note that additional security group IDs attached to the machine pool cannot be modified. To remove or add more security group IDs, replace the entire machine pool with a new one.
+
+* **ROSA CLI update.** The ROSA CLI (`rosa`) was updated to a new version. For information about what has changed in this release, see the link:https://github.com/openshift/rosa/releases/[ROSA CLI release notes]. For more information about the ROSA CLI (`rosa`), see xref:../cli_reference/rosa_cli/rosa-get-started-cli.adoc#rosa-about_rosa-getting-started-cli[About the ROSA CLI].

 * **`VolumeDetachTimeout` configuration applied to machine pools for {hcp-title}.** ROSA is applying a `VolumeDetachTimeout` configuration of 5 minutes to all machine pools. This prevents issues with node deletion when volumes fail to detach. This only applies to {hcp-title}.
 
 * **Configure machine pool disk volume for {hcp-title} clusters.** You can now configure the disk volume size for machine pools in {hcp-title} clusters. The default disk size is 300 GiB, and you can configure it from a minimum of 75 GiB to a maximum of 16,384 GiB. For more information, see xref:../rosa_cluster_admin/rosa_nodes/rosa-managing-worker-nodes.adoc#configuring-machine-pool-disk-volume_rosa-managing-worker-nodes[Configuring machine pool disk volume].
