February 2025 performance summary for alphagov/pay-ci: Delivered initial Concourse runner Docker-in-Docker base image upgrade to 28.0.0-dind-alpine3.21 to address Pact compatibility with Java 21 and Pact v4, and to empower Dependabot to propose major Docker updates. After evaluation, rolled back the upgrade due to stability concerns and updated Dependabot policy to ignore major Docker updates, prioritizing CI reliability. These changes improved image governance and readiness for future updates, with a clear rollback plan if issues arise.
