I've been using rails for well over a decade (since version 2), and loving it. For the most part upgrades have been relatively painless by choosing to always lag a little behind on non-security related upgrades. There have been times though when upgrades have been extremely painful. The massive shift between versions 2 and 3 (merb integration), the openssl shenanigans (ruby v2 -> v3), and the mimemagic / shared-mime-info licensing issues are the major ones that come to mind. That being said, I use Elm on the front end a lot and the confidence it gives me about my code is like night and day compared to ruby (or javascript).
