I always use changelogs and try and link all changes to a pr. I don’t expect people to have to troll through dozens of individual per release notes. Why this has become a lost art is very mysterious to me unless it’s just laziness?

From working in mobile release pipelines, my experience with release notes was that the app stores (esp Apple) would nitpick release notes and hold up releases on a regular basis, so we went to generic release notes to avoid being blocked at approval on the Apple side. Pretty good example of a reverse incentive.
