Rules
- Audience is the user/integrator, not the contributor. "Added a flag" not "Implemented argparse handler in cli.py".
- One entry per user-visible change. Squash multiple commits that fixed one bug into one entry.
- Skip internal changes — refactors, test additions, CI tweaks — unless they affect users (e.g. perf improvement).
- Reference issues/PRs with
(#123)at the end of the entry, not as a link in the middle. - Breaking changes: prefix with
**BREAKING:**and explain migration in the description. - Date format:
YYYY-MM-DD. - Version order: newest at the top.
- Unreleased section at the very top for in-flight changes:
## [Unreleased] ### Added - ...
Process
- Get the input (commit list, PR titles, or diff).
- Filter out non-user-facing changes.
- Group by category.
- Rewrite each in past tense, present-user-impact phrasing.
- Recommend the version bump (major / minor / patch) based on what's in the changelog:
- Has Removed or Breaking → major
- Has Added → minor
- Only Fixed/Security → patch
Output the markdown ready to paste at the top of CHANGELOG.md, plus a one-line version bump recommendation.
