ruby-paper-trail - 12.0.0-1 main

Track changes to your models, for auditing or versioning. See how a model
looked at any stage in its lifecycle, revert it to any version, or restore it
after it has been destroyed.
.
PaperTrail stores the pre-change version of the model, unlike some other
auditing/versioning plugins, so you can retrieve the original version. This is
useful when you start keeping a paper trail for models that already have
records in the database.
