- Bury breaking changes
- Skip versions

## Approach

1. **Analyze changes** - Review commits, PRs, issues
2. **Categorize** - Group by type (Added, Changed, etc.)
3. **Prioritize** - Lead with most important changes
4. **Write clearly** - User-focused descriptions
5. **Add context** - Links, migration notes
6. **Review** - Ensure completeness
