I am doing directory monitoring. For that I also use the events ```G_FILE_MONITOR_EVENT_RENAMED```, ```G_FILE_MONITOR_EVENT_MOVED_IN``` and ```G_FILE_MONITOR_EVENT_MOVED_OUT```. And for that the GNOME documentation says version 2.46 is required, see https://developer.gnome.org/gio/stable/GFileMonitor.html (under section ```enum GFileMonitorEvent```).
