--- upgrade: - | The new StackUpdateType parameter is now set to UPGRADE when a major version upgrade is in progress. This enables application configuration via puppet to distinuish a major version upgrade from a normal stack update (e.g for minor updates or reconfiguration) by inspecting the stack_update_type hiera value. In future other values may be added to flag e.g minor updates vs reconfiguration, but for now only UPGRADE is considered.
