Worked on the visitscotland/dot-com-brxm repository to upgrade its core dependencies to version 15.7, focusing on enhancing security, stability, and performance without introducing functional changes. The approach involved careful management of the Java-based build system and integration with the existing framework to ensure seamless adoption of the latest features and security patches. By updating dependencies, the work reduced potential security vulnerabilities and established a reliable foundation for future development. The process required attention to compatibility and runtime behavior, leveraging skills in dependency management, Java, and build automation tools to maintain operational consistency while preparing the codebase for ongoing improvements.
