 ### Improvements {#improvements-2-7-1}
 * Improves the default host support bundle generated by `./APP_SLUG support-bundle` with better diagnostics for different installation scenarios (such as air gap or proxy installations) and additional network diagnostics collecion. For more information, see [About the Default Embedded Cluster Support Bundle Spec](/vendor/embedded-troubleshooting#about-the-default-embedded-cluster-support-bundle-spec).
+* Updates the Embedded Cluster CLI help menu to use the applciation name instead of the binary name (for example, "Manage the Wordpress Enterprise Admin Console" instead of "Manage the wordpress-enterprise Admin Console").
+* Adds a preflight check to block XFS filesystems with `ftype=0` (`d_type` disabled), which are incompatible with the container runtime.
