I've done the work before to make rails 3.2 work on 2.2. I recall the problem is due to a breaking Bcrypt name change and Yaml serialization, and it's a one line patch. The maintainers are aware of the issue but held back so as to not break every 3.2 installation on a minor upgrade (would have to be called Rails 3.3 for semver?). Rails 4.0 isnt that hard of an upgrade path if you include the attraccessible gem.

It took quite a while before rails released a version of 3.2 that worked.
As for how fun upgrading to rails4 is, you obviously don't have a project with 200 database tables that has models using the attr_protected for the five columns (appwide) that actually need it. Forced whitelisting is not fun, regardless of if it is on model or controller level.
