Hello,
I have an existing project in Jira that's been in use for a couple of years now. I created a scrum board for it. The default filter query brings up all issues, including those that were completed. I changed the query to pick up only open issues, but that makes all the closed issues in the current sprint disappear from the board. I can think only of an option to create a scrum specifically to hold the completed issues from previous releases and go back to the default filter query for the backlog. Are there other options?
