  # Travis should check every minor version in a range of supported versions, because
  # rails does not follow sem-ver conventions, see http://guides.rubyonrails.org/maintenance_policy.html
  # It should be sufficient to test only the latest of the patch versions for a minor version, they
  # should be compatible across patch versions (only bug fixes are released in patch versions).
