问题
Is there a way to find out what is configurable in the initializer -- is it just only version_limit and the deprecated track_associations? I had a look through the the config code and also searched for "PaperTrail.config." in the [README](https://github.com/airblade/paper_trail/blob/master/README.md].
question originally part of Is it possible to configure PaperTrail gem to ignore attributes globally?
