1. Added customizable STI type serialization. …

   Rails will store the name of a child class in the database
   to use for re-instantiating the record as the correct class later.
   By specifying an `inheritance_serializer` and
   `inheritance_deserializer`, you can customize the stored identifier.
   
       class Foo < ActiveRecord::Base
         self.inheritance_serializer = ->(klass) do
           # Map the class to the appropriate type identifier.
           # Defaults to `klass.name`.
         end
   
         self.inheritance_deserializer = ->(type_before_cast) do
           # Map the type identifier back into the appropriate class.
           # Defaults (approximately) to `type_before_cast.constantize`.
         end
       end
   
   This is primarily useful for working with legacy data models.
