Rails 7 and Paper_Trail Gem Compatibility

As of January 19th 2022, you can use paper_trail gem in your Rails 7 app.

But you have to use this in your gem:

gem "paper_trail", git: "https://github.com/paper-trail-gem/paper_trail"

They haven't published the latest version. Also, they are waiting some updates from Rails team.

Caveat: you will get alerts that the paper_trail gem is not compatible with Rails 7.
