1. Use a consistent entry format
For each release, record date or version, change, affected area, and any action users need to take. Keep the format readable across multiple updates.
2. Write for user impact
Explain the task or problem a change addresses and what users should expect. Distinguish a new capability, improvement, and fix without exaggerating the difference.
3. Mention limits and availability
State supported plans, regions, or rollout timing only when verified. If a change is gradual or conditional, tell readers how they can confirm whether it applies to them.
4. Maintain an accurate history
Keep older entries available when they help users understand changes, and correct them transparently if details were wrong. Link to support material for steps that need more explanation.
