MFC version has two parts major and minor. Are you sure that date is the only way to check if the interface has changed? Maybe the major number should stay the same (6) in this case, and the minor should be updates? Do you have contact with persons writing the firmware? Also, I don't see a patch with the newer firmware posted to linux-firmware. When it is going to be sent?
