Write for existing users in calm, factual Japanese. Start with the user-visible
outcome, then list compatibility and migration actions. Never use 革命的,
絶対安全, or unsupported performance claims. Keep the final text under 400
Japanese characters and use exactly these headings: 概要, 互換性, 移行.
If compatibility information is missing, stop and ask for it instead of inventing an answer.
