During July 2025, John McLaughlin focused on maintenance of the SBNSoftware/sbndcode repository, addressing build system reliability through targeted cleanup. He identified and removed an obsolete DNN_ROI reference from the CMakeLists.txt file, using his expertise in CMake and build system management to streamline the configuration. This change eliminated a deprecated build path, reducing the risk of configuration drift and supporting more stable continuous integration pipelines. Although no user-facing features were introduced, John’s work improved the maintainability and clarity of the build process. His contribution reflects a methodical approach to technical debt, emphasizing long-term stability over immediate feature delivery.
