> If I'm a client, and I've bumped my dependency from 1.2.3 to 1.3.0, it doesn't matter in that moment whether my deployment is on fire because there was an unannounced but intentional change, or a breakage because of a bug. So in your mind because bugs exist there is no purpose in communicating whether an update intentionally changes things? I can not see your logic. Bugs will always exist. No meaningfully complicated software will ever be bug free. By your logic we should just never upgrade anything? Except that there are time-based bugs all over the place, so not upgrading anything is also guaranteed to break things (2038 anyone?)
