I'm actually sure that 0.17 will break it. Changes to the fuel flow system, the renaming of parts added in 0.16, New SOI's from the other planets, changes to the game killing the kraken, the improved save/load system. it'll also add new pre-built crafts and have a different folder for unofficial craft. There's also the code for IVA's that may affect existing save profiles because of lack of information in them, etc. It's my honest opinion that 0.17 will have your crafts removed and your entire save removed, alas, that's how it is when a game is in alpha.
