We queue up items for release and we move them into "Ready for Release". This is our "Done" state on a sprint by sprint basis. After Release, we take all tickets in the "Ready for Release" state and move them to Done.
The Sprint Burndown does not recognize the Ready for Release as points completed in the sprint.
Also, we have created statuses for Cancelled, Duplicate, which we want to treat as resolved. Is this just a resolution script setting via Admin?
