There are no errors in a version preceding the change, only warnings. There will be errors and possibly warnings in a version after the change. I don't want to see this stuff prior to upgrade. > a) not everyone will see that Why is that the problem of everyone else? They should take their job more seriously and read the change log. > b) that doesn't help you find anywhere in your code (possibly including in dependencies) that will break when you upgrade ruby, which you need to do. No, running it under the new version will. If there's a need to be ready ahead of time then, for example, the Ruby team could add these warnings as a compile time flag. They had a compile time flag to remove the warnings in a previous release, so it can be done. > Anyway, if you move to another language, come back after a couple years and let us know if you were more or less happy with their breaking change scenarios! :) I'm enjoying Crystal, for many reasons, and I'll be looking at Elixir too. Not sure I can entirely replace Ruby with them but I don't use it for any new projects now.
