During March 2026, Mitto contributed to the rbenv/ruby-build repository by delivering an OpenSSL compatibility update that enabled seamless Ruby 4.0.2 installations. Mitto addressed evolving OpenSSL version constraints, updating requirements to align with newer OpenSSL releases and reduce installation errors. This work involved careful adjustment of package management scripts using Shell and Ruby, ensuring that Ruby 4.0.2 could be reliably installed across diverse environments. By focusing on DevOps practices and dependency management, Mitto improved the upgrade path for users and minimized setup failures. The depth of the contribution lay in resolving compatibility issues at the intersection of Ruby and OpenSSL.
