I took a 13,000 line Rails 7.0 app and updated it to 7.1. I had to change 1 line of test configuration code to make everything work beyond the diff between 7.0 and 7.1[0].
I would say that's a success for having an easy upgrade path. Now the fun part is going back to refactor some of the code to use the new features in 7.1.
If anyone is curious, I updated my Rails / Docker example app to use 7.1 too https://github.com/nickjj/docker-rails-example. Even though Rails 7.1 comes with a Dockerfile, there's still a lot of opinions you can add such as using Docker Compose to have a fully working out of the box experience that works in development and production -- complete with Postgres, Redis, Action Cable, Sidekiq and more.
