+          validates_presence_of :title, on: :update
+        end
+
+        person = Person.new
+        person.valid?([:create, :update])    # => false
+        person.errors.messages               # => {:name=>["can't be blank"], :title=>["can't be blank"]}

     *Jay Elaraj*

     `ActiveModel::Dirty#[attr_name]_previous_change` to improve access
     to recorded changes after the model has been saved.
