I downloaded the latest update (v1.08.0080) for Phantom 3 advanced on 4/11/2016. When I extract the bin file it has a file size of 64,544kb. I thought about installing that fw update today, and decided to re-download the update, and the extracted bin file size is now 61,143kb. Was there a change made to fw update 1.08.0080 in the past few weeks? Why the difference in file size??
