I just released version 0.28 of Wammu. This release fixes various problems found by users. Full list of changes:

• Fixed freeze while searching for Bluetooth devices.
• Fixed guided configuration of Bluetooth devices (no more complains about not existing device).
• Fixed saving of backups to folder with non ASCII names.
• Validation is less strict and allows hopefully all number.

This release also comes with binary for Windows with embedded Gammu 1.20.0.
