I don’t really get the purpose of your plugin. Why would one need a
plugin to tell them that a != b? Like your example:

pet1 = Pet.new :id=>1, :name=>“dog”, :value=>“Tiny”
pet2 = Pet.new :id=>5, :name=>“cat”, :value=>“Norm”

differences = pet1.differences(pet2)
=> {:value=>[“Tiny”, “Norm”], :name=>[“dog”, “cat”], :id=>[1, 5]}

Could you tell us in a real practical example how and why would one use
this plugin?

The reason it was originally created was for an audit log. Before saving the model, it was compared to the model that is stored in the database, and then the differences are logged.

Well, if that was the main purpose of your plugin than I’d say the
current version is completely off because you don’t offer an option to
store the differences in a log.

The plugin itself was not meant to store the differences in a log, the
plugin was the mean to offer the developer the ability to compare 2
ActiveRecord objects. Anything could be done with that comparison, like
store a log of changes.
