Rails is in many ways as (more?) backwards-incompatible as Haskell. E.g.,
Rails 4 requires(!) Ruby 1.9.3+. 1.9.3 was released in the fall of 2011.
When new major versions of Rails or Ruby come out, developers are generally
expected to make the incremental changes to keep up. It's the "donkey in a
well" thing -- you never get buried if you make small changes over time.
