What’s new

Battery software updates: your battery can now be updated from the app (if available). It checks the charge level, shows how long it takes and stops safely if interrupted.

Rename your battery: give each one its own name.

Easier service: send a service report from the app, with your battery's details attached.

Better connections: finding and reconnecting is faster and far more reliable. Saved passwords are remembered.

Plus new icons, a clearer menu and many smaller fixes.
