I just updated a rails app through about 3 years worth of versions and it was minimal effort. Not sure what you mean by this. Rails seems to be very stable at this point.
Rails is definitely way more stable over the past 3 years than it was the 3 years before that. It's settled down. For better or worse.
The last few versions added a bunch of really nice features but it seems the existing features are considered still good and not in need of change.
Would you mind expanding on this? I went from Django to Rails and loved it so I'm always genuinely curious about the experiences of people who didn't have the same fun as me.
It was 4 years ago. I could never work rbenv and bundler to play nicely when cloning the project on the second machine. But I am willing to give it another go.
