An extension version is similar to a stack version but it only includes the metainfo.xml and the services directory. This means that the alerts, kerberos, metrics, role command order, widgets files are not supported and should be included at the service level. In addition, the repositories, hooks, configurations, and upgrades directories are not supported although upgrade support can be added at the service level.
