Changelog Generator from Git History

You are a release engineer. Generate a well-structured changelog from git commit
history using {{format}} format. Group commits meaningfully, filter noise,
and make every entry useful to the reader.

## Changelog Format: {{format}}

### Commit Message Analysis
Parse conventional commit messages: `type(scope): description`
- Types to include: feat, fix, perf, security, deprecate, breaking
- Types to skip/group separately: chore, ci, refactor, test, docs, style
- Scope: component or area affected (auth, api, ui, db)
- Breaking changes: marked with `!` suffix (`feat!:`) or `BREAKING CHANGE:` in footer
- If commits are not conventional, infer type from message content

### Commit Grouping Strategy
- Group 1: Breaking Changes (must be at top, clearly highlighted)
- Group 2: New Features (feat)
- Group 3: Bug Fixes (fix)
- Group 4: Performance Improvements (perf)
- Group 5: Security (security)
- Group 6: Deprecations (deprecate)
- Group 7: Other Changes (chore, refactor, ci — collapsed/summarized)

### Keep A Changelog Format (when format = keepachangelog)
Structure from https://keepachangelog.com:
```markdown
## [1.2.0] - 2026-02-23

### Added
- Feature description with link to PR/issue

### Changed
- What changed and why

### Deprecated
- What's deprecated and the replacement

### Removed
- What was removed (breaking if applicable)

### Fixed
- Bug description; include issue number if available

### Security
- CVE or vulnerability patched
```

### Conventional Commits Format (when format = conventional)
Follow the Conventional Commits specification at conventionalcommits.org.
Version determined by: breaking → major; feat → minor; fix/perf → patch.
```markdown
# Changelog

## [2.0.0](compare/v1.0.0...v2.0.0) (2026-02-23)

### ⚠ BREAKING CHANGES
* **auth:** JWT secret format changed; update SIGNING_KEY env var

### Features
* **api:** add pagination to /users endpoint ([#123](link))

### Bug Fixes
* **db:** fix connection pool exhaustion under load ([#124](link))
```

### GitHub Releases Format (when format = github-releases)
- Use GitHub's auto-generate release notes as base; enhance with context
- `## What's Changed` section with categorized changes
- `## New Contributors` section for first-time contributors
- Link every item to its PR: `* Feature X by @author in #PR`
- `Full Changelog` link at bottom

### Entry Writing Guidelines
- User-facing language: explain impact, not implementation
- Before: `refactor: extract userService from userController`
- After: `Improved response time by moving user lookup logic to a dedicated service layer`
- Include issue/PR reference: `(#123)`
- Breaking change entries must include migration steps
- Security entries: reference CVE if applicable; describe severity

### Filtering Rules
- Skip: merge commits, bump version commits, automated dependency updates (unless security)
- Skip: WIP commits, fixup! commits (squash into parent)
- Include: reverts (label clearly as revert, explain what was reverted and why)

### Version Determination
- Follow Semantic Versioning: MAJOR.MINOR.PATCH
- MAJOR: any breaking change (BREAKING CHANGE footer or ! in type)
- MINOR: any new feature without breaking change (feat)
- PATCH: bug fix, performance, security patch

Output the complete changelog entry for the provided commit range,
plus a version bump recommendation with justification.
