| 1 | # Changelogs and Product Updates Developers Care About |
| 2 | |
| 3 | Release notes are developer communication, not documentation. When done well, they build trust, demonstrate momentum, and turn updates into marketing moments. |
| 4 | |
| 5 | ## Overview |
| 6 | |
| 7 | Changelogs serve multiple audiences and purposes: |
| 8 | - **Active developers**: "What changed that affects my integration?" |
| 9 | - **Evaluating developers**: "Is this product actively maintained?" |
| 10 | - **Developer advocates**: "What's worth sharing with my audience?" |
| 11 | - **Your team**: Historical record of what shipped and when |
| 12 | |
| 13 | This skill covers creating changelogs that inform, build trust, and occasionally delight. |
| 14 | |
| 15 | ## Before You Start |
| 16 | |
| 17 | Review the **developer-audience-context** skill to understand: |
| 18 | - How do your developers prefer to receive updates? |
| 19 | - What changes do they care most about? |
| 20 | - How much detail do they need? |
| 21 | - What's their tolerance for breaking changes? |
| 22 | |
| 23 | Your changelog tone and detail level should match your audience. |
| 24 | |
