-Only RHEL 7.9 is supported in {product-title} {product-version}. You must not upgrade your compute machines to RHEL 8.
+Adding {op-system-base} 7 compute machines to an {product-title} cluster is deprecated. Deprecated functionality is still included in {product-title} and continues to be supported; however, it will be removed in a future release of this product and is not recommended for new deployments.
+
+In addition, you must not upgrade your compute machines to {op-system-base} 8 because support is not available in this release.
+
+For the most recent list of major functionality that has been deprecated or removed within {product-title}, refer to the _Deprecated and removed features_ section of the {product-title} release notes.
