 - **n8n 2.1.0+ compatibility** - Switch to static ffmpeg binary (apk removed upstream in n8n 2.1.0)
 
 ### Changed
+- **Postgresus → Databasus** - Rebrand to Databasus with new Docker image `databasus/databasus:latest`. Now supports PostgreSQL, MySQL, MariaDB, and MongoDB backups
 - **Git sync** - Replaced `git pull` with `git fetch + reset` for more reliable updates (handles accidental local commits)
