The Status Updater for Atlassian Jira add-on uses JQL-based update triggers to transition issues. Issue status updates are bound to the workflow that is valid to the state of the issue.
The update triggers are executed every 60 minutes. The updater will try to transition the issue through the workflow to reach the specified status. If the status transition is not valid, the issue will not be updated. Issue transition is done using the account privileges of the trigger creator.
A comment can be added to the issue to explain the transition and e-mail notifications can be sent automatically.
