DEPRECATION WARNING: The behavior of attribute_changed? inside of after callbacks

[noctivityinc]

In Rails 5, we are getting the deprecation warning for the way attribute changed is handled, I believe in the notify method inside of observers.rb.

According to the message:

DEPRECATION WARNING: The behavior of `attribute_changed?` inside of after callbacks will be changing in the next version of Rails. The new return value will reflect the behavior of calling the method after `save` returned (e.g. the opposite of what it returns now). To maintain the current behavior, use `saved_change_to_attribute?` instead.

Here's a good article I found on the issue:
