 * **Cluster install update.** {product-title} clusters can now be installed on {GCP} shared VPCs. For more information, see xref:../osd_install_access_delete_cluster/creating-a-gcp-cluster.adoc#osd-create-gcp-cluster-ccs_osd-creating-a-cluster-on-gcp[Creating a cluster on GCP with CCS].
 
 * **{product-title} on Google Cloud Marketplace availability.** When creating an {product-title} (OSD) cluster on Google Cloud through the Hybrid Cloud Console, customers can now select Google Cloud Marketplace as their preferred billing model. This billing model allows Red Hat customers to take advantage of their link:https://cloud.google.com/docs/cuds[Google Committed Use Discounts (CUD)] towards {product-title} purchased through the Google Cloud Marketplace.

+* {OCP} 4.14 introduced an updated HAProxy image from 2.2 to 2.6. This update created a change in behavior enforcing strict RFC 7230 compliance, rejecting requests with multiple `Transfer-Encoding` headers. This may cause exposed pods in {product-title} 4.14 clusters sending multiple `Transfer-Encoding` headers to respond with a `502 Bad Gateway` or `400 Bad Request error`. To avoid this issue, ensure that your applications are not sending multiple `Transfer-Encoding` headers.

 * If you configure your cluster using external OIDC configuration and set the `--user-auth` flag to `disabled`, the console pods might enter a crash loop. (link:https://issues.redhat.com/browse/OCPBUGS-29510[*OCPBUGS-29510*])
 * The OpenShift Cluster Manager roles (`ocm-role`) and user roles (`user-role`) that are key to the ROSA provisioning wizard might get enabled accidentally in your Red{nbsp}Hat organization by another user. However, this behavior does not affect the usability.
 * The `htpasswd` identity provider does not function as expected in all scenarios against the `rosa create admin` function.
