Make an effort to automatically show what changed between versions

[lvh]

This is a pie-in-the-sky wishlist feature, and I don't expect you to do anything about it, but...

Let's say I have a major project with tons of dependencies that haven't gotten updated recently. Easily 2 dozen deps have new versions. Most of them boring minor bumps, some of them less minor. Automatedly updating them can sometimes work but obviously you run into interdependencies.

I do this interactively, and go though the following pattern:

1. Look up project website
2. See if it has a CHANGELOG.md and see what changed
3. Look at the commits between this tag and the previous one (if tags exist)
4. Go to next update

Some of this, specifically steps 1 through 3, look like they could be automated :)

Oops; sorry for the terrible title; forgot to edit that.

I can't say anything about effort necessary, but this would be a nice addition to the interactive upgrade mode - instead of just yes/no I could imagine there being options like changelog/commits/ web.

Definitely an interesting idea!
