+## [1.1.0] - 2025-12-28
+
+* * **Backup:** Log a warning and skip database dumps when no databases.csv entry is present instead of raising an exception; introduce module-level logging and apply formatting cleanups across backup/restore code and tests.
+* **CLI:** Switch to an FHS-compliant default backup directory (/var/lib/backup) and use a stable default repository name instead of dynamic detection.
+* **Maintenance:** Update mirror configuration and ignore generated .egg-info files.

 ## [1.0.0] - 2025-12-27
 
 * Official Release 🥳
