Ruby's 1.9/2.0 upgrade had pretty similar changes to Python 3. For example, in Ruby 1.8.7, 'hello'[1] returned 101, whereas now it returns 'e', and String#each doesn't even exist anymore. Similarly, string encodings became significant in both Ruby and Python's breaking changes. It seemed to me like the Ruby ecosystem just didn't drag its feet as much as Python's (probably largely because Rails had enough pull to drag the Ruby ecosystem along with it, and Rails enthusiastically supported Ruby 2).
