I’ve seen this a few times with various distributions. People always say stuff about checking news files or whatever their distros call them. I have no idea what those are or where to find them. It would seem extremely prudent for the update tool to print relevant information.

Brew does this. (I am not using Brew as an example of a perfect package management tool.) It also has “caveats” that get printed for some packages. It seems much more useful this way.

Printing the entire change log is overkill, but at least breaking changes and such would be extremely useful.
