Added release note, rebased to trigger CI again.

FWIW I don't remember this happening on any of the ~3 machines I tested on previously, and it only happens on interrupt, not normal execution. If you think this should be backported, let me know if there is anything I can help with.

If/when ready you can go ahead and merge this, I have no commit access.
