paper_trail 12.0.0

12.0.0 (2021-03-29)

#1281 Rails: Instead of an Engine, PT now provides a Railtie, which is simpler. This was not expected to be a breaking change, but has caused trouble for some people:
- Issue with the deprecated autoloader = :classic setting (https://github.com/paper-trail-gem/paper_trail/issues/1305)
Rails: The deprecated config.paper_trail configuration technique has been removed. This configuration object was deprecated in 10.2.0. It only had one key, config.paper_trail.enabled. Please review docs section 2.d. Turning PaperTrail Off for alternatives.

where_object_changes_from queries for versions where the object's attributes changed from one set of known values to any other set of values.
