0.11.0

Summary

Version 0.11.0 brings significant architectural changes to enhance database reliability and performance. The major changes include:

1. Database Engine Change: Replaced sqlx with rusqlite as the SQLite database driver and removed support for redb. This change provides better performance and reliability for database operations.

2. Transaction Management: Introduced robust database transaction support that encapsulates all database changes. The new Transaction trait implements a rollback operation on Drop unless explicitly committed, ensuring data integrity.

3. Race Condition Prevention: Added READ-and-lock operations to securely read and lock records from the database for exclusive access, preventing race conditions in concurrent operations.

⚠️ Important Migration Note for redb Users

If you are currently running a mint with redb, you must migrate to SQLite before upgrading to v0.11. Follow these steps:

1. Stop your current mint
2. Back up your database
3. Use the migration script available at: https://github.com/cashubtc/cdk/blob/main/misc/convert_redb_to_sqlite.sh
4. Update your config file to target the SQLite database engine
5. Start your mint with v0.11
