Best Practices

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

1. Impact first: Most important changes at top
2. Group logically: By feature area or type
3. Be consistent: Same format throughout
4. 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
