July 2025: Consolidated the UAT testing workflow for the aws-greengrass/aws-greengrass-lite repository to boost CI/CD reliability, test visibility, and maintainability. Created a single uat.yml and introduced a matrix strategy to run categories (component, deployment, fleet-status, runtime, security) within one workflow, with fail-fast disabled to ensure complete test results across categories. This change provides comprehensive feedback loops and clearer CI/CD metrics for stakeholders.
