In December 2025, Jan Flammang contributed to the strapi/strapi repository by implementing Luxembourgish locale support in the Strapi internationalization plugin. He expanded the plugin’s localization capabilities by adding the lb-LU locale, directly addressing the need for broader language coverage and improving the user experience for Luxembourgish-speaking users. Jan’s work involved editing and extending JSON locale files, ensuring accurate integration with the existing i18n infrastructure. This targeted enhancement aligned with business goals to reduce localization friction for Luxembourg-based installations. His contribution demonstrated focused application of JSON, i18n, and localization skills, delivering a single, well-scoped feature within the project.
