Patricia Nilsson developed a Semantic Versioning System for the fungover/breeze repository, focusing on robust version management within the application. She designed and implemented a Version class in Java that handles parsing, validation, and comparison of version numbers according to SemVer standards. To ensure reliability and correctness, Patricia wrote comprehensive unit tests, integrating them with the existing version control workflow. Her work addressed the need for improved release hygiene, compatibility checks, and packaging reliability. By concentrating on semantic versioning and thorough testing, Patricia demonstrated depth in software development, unit testing, and version control, delivering a focused and maintainable feature.
