In addition to being able to link multiple PRs to one Issue, you can now link multiple Issues to one PR. Yep, we know that sounds pretty confusing. But don’t worry - the feature is very straightforward!
If several issues can be resolved with a single PR (for example, duplicate bug reports), you can connect all of those issues to the PR. As the PR moves through the board, the Issues will automatically follow - no need to update each individual ticket.
