charm-verion

status.FullStatus returns a field called "charm-verion"
type ApplicationStatus struct {
 Err *Error `json:"err,omitempty"`
 Charm string `json:"charm"`
 Series string `json:"series"`
 Exposed bool `json:"exposed"`
 Life life.Value `json:"life"`
 Relations map[string][]string `json:"relations"`
 CanUpgradeTo string `json:"can-upgrade-to"`
 SubordinateTo []string `json:"subordinate-to"`
 Units map[string]UnitStatus `json:"units"`
 MeterStatuses map[string]MeterStatus `json:"meter-statuses"`
 Status DetailedStatus `json:"status"`
 WorkloadVersion string `json:"workload-version"`
 CharmVersion string `json:"charm-verion"`

I'm guessing that should be "charm-version".

I don't see anything that references it
