Changelog report cards

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.

Board average: 87/100 · median 84/100 · 79 of 85 (93%) score B or better

A 42 (49%)
B 37 (44%)
C 3 (4%)
D 3 (4%)
F 0 (0%)

Language: All (100) Rust (26) TypeScript (20) Go (18) C (9) JavaScript (9) C++ (7) Python (7) Ruby (3) Java (2) Zig (2) C# (1) Crystal (1) Dart (1) Elixir (1) Erlang (1) HCL (1) Julia (1) Kotlin (1) Lua (1) PHP (1) Swift (1)

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.
