Kodi update question

I am currently running 16.1 Jarvis. With the release of 17. now out I am wondering how long will 16.1 work until it begins to not let the add ons work anymore? My device can’t run the new 17 , it is not compatible. I am researching as I am posting this to get the 5.0 Lollipop update. I have looked in ChinaGadgets Review but their site doesn’t show the box that I have so I am still looking. Thanks Guys, Lance
