Summary

The minimum supported Python version has been raised to 3.9. The user manual has migrated to a new format and build system, now including sections on user callbacks and detailed example scripts. The code base has undergone extensive refactoring. FCron support has been added. The English strings in the GUI have been optimized. Serbian language is now available in both Latin and Cyrillic scripts. Interlingua (Occidental) has been introduced as a new language. The libnotify-bin (notify-send) dependency has been removed, as Back In Time now uses DBus for notifications.
