Kodi 16 vs Kodi 17

Hey guys, I am a newbie to this forum, but i am curious if someone can provide me with the knowledge whats the pros and cons from switching to kodi 16 to kodi 17. I am using kodi 16 (Jarvis) on my amazon fire stick (2nd gen) having almost no problems at all (besides a few minor buffering issues during movies). I am not sure if i should be switching to kodi 17, i don’t want any problems if i do switch, so maybe i should leave it the way it is. Also will kodi eventually force kodi 16 users to upgrade to kodi 17?

Thank you,
Matt
