In May 2025, Marco Lin focused on improving localization quality and UI consistency in the ramsey/web-php repository. He addressed a Brazilian Portuguese language bug by correcting the display name and removing an extraneous colon in the change_language string, ensuring accurate and standardized language presentation across the user interface. Using PHP and INI files, Marco applied targeted code corrections that adhered to global localization conventions, simplifying future translation efforts. His work reduced copy-related support issues and enhanced the user experience for Portuguese-speaking users. The changes were low-risk, reviewable, and contributed to a more polished, internationally ready product.
