TGY-I6S Firmware Update

When can we expect the Firmware update for the TGY-I6S radio? This firmware update is needed to fix the limited range that has been reported by many users. Sometimes the range reported by users is less than 100 meters, there are many toy grade radios that exceed this range. I noticed the FlySky version of this radio has the updated Firmware which fixes the range issues while adding new features. Please let me know as this has the potential to be a great hobby grade radio and I would like to use it with my next plane..
