Writing Good Entries
✅ Do:
- Write from user's perspective
- Be specific about what changed
- Include relevant issue/PR numbers
- Group related changes
❌ Don't:
- Use technical jargon for user-facing notes
- Include internal changes in public changelog
- Be vague ("various fixes")
- Include commit hashes in user docs
Organizing Changes
- Impact first: Most important changes at top
- Group logically: By feature area or type
- Be consistent: Same format throughout
- Date everything: Clear version dates
Limitations
- Cannot access git repositories directly
- Requires commit messages or change descriptions as input
- Cannot verify semantic versioning automatically
- Technical details should be verified by developers
