When you add this validator to a transition with the required options and trigger the transition, the add-on checks the history of the Status field. If the issue has previously been in the selected status, then the issue will progress to the destination status of the transition. If not a validation failure message will be displayed.
Customize this validator using the additional option provided as a part of the validator. The options is :
- Most recent status only
Checks only for the most recent status of the issue, excluding the current status. The issue will progress to the destination status of the transition only when the issue's selected status is the most recent status, excluding the current status.
