- This version of the gem ONLY SUPPORTS Rails 3.x. For 2.x support, check out the branch 'rails_2_3' (or version .5 of the gem)
- patched has_and_belongs_to_many associations, for secondbase models, so that ActiveRecord understands that the join table is in the secondbase.
- patched ActiveRecord::TestFixtures so that transactional fixture support is respected for the SecondBase.
- reorganized monkey patches to make it easier to work in fixes for different versions of rails.
