1. Fixed a bug which was causing an error for some users: "Error entering upgrade mode" when trying to do a Firmware Update or "Save to KeyMouse Devices".
2. Additional firmware for 47T7. 48T1 is still the latest in terms of features, but 47T7 is another test at resolving stuck key layer issues. If you have issues in 48T1, you can revert back to 47T7. Basically these different versions have different debounce timings and similar.
3. Ability to check current firmware version on the devices. From the "Firmware Update" screen, select a device from the list (selecting it, not just checking the box), and then click "Check Version on Device". Wait a moment, and it will show you the version #'s for the Bluetooth Module, and the USB Chip. We'll improve interface for this in the next version.
