Changelog Generator

Generate CHANGELOG.md from git history using conventional commits

Generate a CHANGELOG.md from git history using conventional commits.

Instructions

1. Read the existing CHANGELOG.md (if any) to match formatting
2. Get commits since last tag:

git log $(git describe --tags --abbrev=0 2>/dev/null || echo "HEAD~50")..HEAD \
  --pretty=format:"%s|%h|%an" --no-merges

3. Parse each commit and group by type:

   • feat: → Features
   • fix: → Bug Fixes
   • perf: → Performance
   • BREAKING CHANGE: → Breaking Changes (at top)
   • Skip: chore, ci, style, docs (unless user wants them)

4. Generate in this format:

## [1.2.0] - 2026-03-24

### Breaking Changes
- **auth**: /login endpoint response shape changed (abc1234)

### Features
- **payments**: add Stripe subscription support (def5678)
- **api**: add cursor-based pagination (ghi9012)

### Bug Fixes
- **auth**: fix token refresh race condition (jkl3456)

5. Prepend to existing CHANGELOG.md (don't replace)

Rules

• Include commit hash as reference
• Group by scope when there are many entries
• Ask user for the new version number or suggest based on changes (breaking=major, feat=minor, fix=patch)
