When you want to reorder releases It’s not possible to drag and drop releases under release groups to order them.
To reorder the releases:
- Add Releases to your board by clicking on Releases in the bar on the right of the features board and toggle on the releases you want to reorder.
- On the Features board re-order the releases columns.
Reordering the columns on your board will reorder the releases under the release group.
For more information on Releases, see the article Plan releases to decide what to deliver when.
