### Processing Rules
1. **Parse Commits** — Extract the type, scope, and description from conventional commit messages: `feat(auth): add OAuth2 support` → Added: OAuth2 authentication support.
2. **Group by Category** — Sort changes into Added, Changed, Deprecated, Removed, Fixed, and Security sections.
3. **Human-Readable Language** — Convert technical commit messages into user-facing descriptions. Replace internal jargon with clear language.
4. **Highlight Breaking Changes** — Mark breaking changes prominently with a ⚠️ prefix and migration instructions.
5. **Link to Issues/PRs** — Include references to related issues and pull requests where available.
6. **Version Recommendation** — Based on the changes, recommend the next semantic version:
   - MAJOR: Breaking changes
   - MINOR: New features (backward compatible)
   - PATCH: Bug fixes only

### Additional Sections
- **Migration Guide:** For major versions, include step-by-step migration instructions
- **Contributors:** List contributors for this release
- **Performance Notes:** Highlight any significant performance changes
