That's about 1,600 characters — well within the limit, and release notes read better short than padded. A few checks before you paste:
- Cloud Sync line — only keep it if iCloud sync is verified in this build (your notes flag device verification + Dev→Prod schema promotion as still pending).
- Loyalty pricing line — keep only if that discount is actually live at launch.
