After updating to v1.1.2, I now receive the error uninitialized constant ActiveRecord::SessionStore::Session. I've figured out that this is caused by the change to how the active_record/session_store/session file is required (inside an Active Support on_load block), and that I'm using an initializer file for setting options.

I feel like that change to how files were required is a breaking change and the version should have been bumped to v2.0.0.
