But it's right here: https://github.com/mui-org/material-ui/releases/tag/v3.0.0

Surprised the "How it works" section of the README doesn't talk about where it actually looks for changelog information (Github releases? CHANGELOG.md? material-ui has both and they are very thorough and consistent)

Looking at the code, it looks like this package just tries to build a list of git commit messages.

In a well-maintained package, Github releases are going to be a better source of information than the commit messages. That or CHANGELOG.md. In many packages I've seen, it's not loud and clear from the commit messages what the breaking changes are in a major release.

The only major exception is semantic-release packages, where devs have to adhere to specific commit message formats for semantic-release to build the changelog info correctly for Github releases.

Nevermind this, obviously this package is only intended for generating information to add to a changelog. I came here looking for a command to quickly show changes (esp. breaking changes) of newer versions of packages I use. I'll probably just write my own tool to do that
