It will work just fine. When there is a big update to the operating system the app developers push out updates themselves to comply with the new OS updates. Foreflight is good about sending users information on new updates but I don't recall Jepps sending notices on app updates when the new OS comes out. But everything should work fine. Also when a new operating system comes out they tell you what's new and what they are improving before you download the new update. Those app developers are always doing maintenance on their apps to improve performance so i wouldn't worry. As long as all your information is backed up you will be ok. I use Log 10 Pro and haven't had any issues at all ever.
