I second this. I recently did a port from Ruby 1.8.7 to 2.1.2 for a large Rails app (approx. ~350kloc between test and app) and in the process I was forced to update lots of dependencies. In a few places so called "minor" patches had big effects. It became clear to me that when your app gets to a significant size juggling the interactions of constantly moving versions of your Gems, Ruby, and Rails causes things to become complicated quickly.
