During December 2025, David focused on enhancing the luanti-org/luanti repository by delivering a comprehensive Czech localization update. He translated menus, error messages, and in-game strings, raising translation coverage to over 81 percent and improving accessibility for Czech-speaking users. David integrated a Weblate-based translation workflow, enabling a scalable and maintainable approach for future localization efforts. His work involved close collaboration with both localization and development teams to ensure translations aligned with UI/UX and gameplay requirements. Utilizing PO files and applying skills in localization, software development, and translation, David established a robust foundation for ongoing multilingual support within the project.
