Hm. That's very generic and seems to only describe the software behavior from a user perspective. When I'm looking for a change log, I'm thinking of something like this: https://github.com/evcc-io/evcc/releases (came to mind because evcc was the last thing I updated).
Yeah, well, that does sound like a problem. How can I take responsibility for a production environment based on upstream being like "Yeah, we fixed the bug you reported in a solid way, trust us bro."
It still doesn't tell us what was changed in the system, just what are the terms to use it. If you're using your license agreement instead of release notes or changelog to communicate what's new, you're doing it wrong.
