Show HN: brew changelog – find upstream changelogs for Homebrew packages (github.com)

I often wanted to see what changed in a Homebrew package — but changelogs are usually buried somewhere in the upstream repo.

So I made `brew changelog`. It parses the formula or cask, looks at the upstream repo, and tries to locate changelog-like files: CHANGELOG, NEWS, HISTORY, etc. Then it either prints the changelog to terminal or opens it in your browser.

brew tap pavel-voronin/changelog

brew changelog node -o

You can tweak behavior with options like --pattern, --print-url, or --allow-missing (try --help)
