Ruby Evolution: New Ruby Features Added in v2.0 through v3.1 — Victor checks in from Ukraine (where Russia’s invasion continues – here are ways you can help the Ukrainian people) with a handy resource covering the key changes to the Ruby language in versions 2.0 onward. This is a fantastic way to check your knowledge of modern Ruby features and bring yourself up to date where needed. For example, did you know File.readlines has a built-in chomp feature now?
