 #### Accessing via GUI
 
 If you launch the virtualbox GUI you should find the vagrant vms named
-`CFEngine Enterprise {{site.cfengine.branch}}.{{site.cfengine.latest_patch_release}}-{{site.cfengine.latest_package_build}} hub`, and `CFEngine Enterprise {{site.cfengine.branch}}.{{site.cfengine.latest_patch_release}}-{{site.cfengine.latest_package_build}} agent host001`. Additionally, you can uncomment the `v.gui=true`
+`CFEngine Enterprise {{site.cfengine.branch}}.7-{{site.cfengine.latest_package_build}} hub`, and `CFEngine Enterprise {{site.cfengine.branch}}.7-{{site.cfengine.latest_package_build}} agent host001`. Additionally, you can uncomment the `v.gui=true`
 option in the `Vagrantfile` to have the console gui start with the vms.
 **Note:** There are two `v.gui` settings to uncomment; one for the hub, and one
 for the clients.
