In February 2025, Juan Rosental upgraded the CI/CD environment for the codeready-toolchain/toolchain-e2e repository by migrating core GitHub Actions workflows to Ubuntu 24.04. This work focused on updating YAML-based workflow definitions to leverage the latest operating system features and improve the reliability of automated build and test pipelines. Using his expertise in CI/CD and GitHub Actions, Juan ensured that the transition was seamless across multiple workflows, resulting in a more stable and future-proof testing environment. While the scope was limited to a single feature and did not involve bug fixes, the upgrade addressed infrastructure modernization and workflow consistency.
