# Format the changelog for a release

Bring the `Unreleased` section of `CHANGELOG.md` into release shape.

## Steps

1. Read `CHANGELOG.md` and collect every entry under the `Unreleased` heading.
2. Group the entries by change type and order the groups as
   [references/changelog-guide.md](references/changelog-guide.md) specifies.
3. Per references/changelog-guide.md, keep at most 12 entries per group; fold the overflow into
   a single "and N smaller changes" entry at the end of the group.
4. Replace the `Unreleased` heading with the release version and today's date, and add a fresh
   empty `Unreleased` heading above it.
5. Never rewrite entries under an already-released heading.

## Output

Show the reformatted section and wait for the user to confirm before writing the file.
