Worked on the microsoft/azure-pipelines-agent repository to enhance deprecation governance by updating the deprecation detection script for Ubuntu 20 images. Using PowerShell scripting, extended the list of deprecated image names within the deployment script, enabling automated identification and flagging of pipelines that rely on end-of-life Ubuntu 20 images. This approach centralized image retirement data, improving maintainability and ensuring alignment with deprecation policies. The update reduced the risk of unsupported image usage in CI environments and provided customers with clearer migration paths. The work focused on scripting and automation, supporting more reliable build processes and streamlined upgrade planning for users.
