Rafi Jacoby worked on preparing the SuperGoodSoft/solidus repository for Rails 8 compatibility, focusing on both application code and continuous integration workflows. He updated version constraints and expanded the CI test matrix to include Rails 8, ensuring that new changes would be exercised against the latest Rails release. Using Ruby and YAML, Rafi refined API spec error matching to reflect updated Rails 8 behaviors and aligned the Gemfile’s sqlite version with the CI environment for consistent test results. His work enhanced test coverage for Rails 8 upgrade paths, reducing risk and supporting a smoother transition for downstream users and customers.
