update version

Hi

I am a fairly New user to Kodi, just like to say WOW so impressive, big thank you to all the developers
i am using Jarvis 16.1 Git:20160424-c327c53 Apr 24 2016
Can i down load the latest Jarvis 16.1 and will it just install over the top so i don’t lose all my ad dons
and is their a way to turn on automatic update ?

any help would be greatly appreciate
