Improved
- Recover incomplete earlier migrations with serialized, bounded retries while preserving settings, orders, encrypted originals and submission history.
Fixed
- Verify required database tables, columns and indexes before marking a migration complete or enabling document/audit features.
Compatibility changes
Upgrade the existing installation with a consistent database/private-originals/encryption-material backup. Preserve accepted or unknown dispatch history. No uninstall, schema reset, silent reconstruction or repeated sending.
