Changelog report cards — how popular open-source projects score

100 popular open-source projects, graded by the free Wakelog changelog linter — the same automated checks anyone can run on their own CHANGELOG.md or GitHub Releases: dates, ordering, vague titles, commit dumps, breaking-change flagging and more. Re-graded daily.

Go average: 92/100 · median 92/100 · 18 of 18 (100%) score B or better

The score measures one narrow thing: how a project's release notes read to strangers — the structural practices from our guides, not prose quality. A lower grade is not a judgment of the software; these are all excellent projects. Every grade links to its full report, finding by finding.
