3 years ago - Using ubuntu-18.04 because the mysql2 gem won't compile against MySQL 5.7 otherwise. MySQL 5.7 is being used for older Rails version compatibility.
- Running Rubocop before Appraisal gets set up, as it otherwise tries to load the vendored gems' Rubocop configuration.
- Removed MRI 2.3 as it would require ubuntu-16.04. While I'd like to continue supporting 2.3 and won't actively break anything for it, testing against it has become too much of a hassle.
