As a PM I do not want to see releases on my board that I am not working on or have already been shipped SO THAT my feature board is clean and only shows relevant information.
It is useful to filter based on feature attributes but it will be more helpful to filter releases based on release attributes. Also you should look into the possibility of archiving releases.
|Release time frame|
We have shipped updates on the Release roadmap screen which allows for better filters on releases. At the top of the list shows active release for each product. Shipped releases are shown as a 2nd section much lower on the dropdown.
