Writing Actionable Changelogs & Release Notes

Vague release notes like 'Miscellaneous bug fixes and improvements' destroy trust in a design system. Product squads need to know exactly how a release affects their work.

A high-quality design system changelog should always include:

1. What Changed: A clear, human-readable summary of the feature, bug fix, or visual update.
2. Visual Before & After: Screenshots or interactive GIF comparisons showing the update in both light and dark modes.
3. Impact Assessment: Does this require squad action, or is it a transparent fix?
4. Migration Code Snippet: If a prop or token changed, provide copy-pasteable before-and-after code blocks showing how to update.
