I had RC1 and updated all packages today. After the update my mobile broadband Huawei E367 stopped working. I traced it to usb_modeswitch update. I manually modified the /usr/lib/udev/rules.d/40-usb_modeswitch.rules and /usr/share/usb_modeswitch/12d1:1446 back to the previous version to get it working again.
