During December 2024, Databio delivered a full Catalan translation for the Jellyfin UI in the jellyfin/jellyfin repository, expanding accessibility for Catalan-speaking users. The work was implemented using JSON and integrated through the Weblate translation platform, ensuring a streamlined and traceable workflow. Databio focused on localization and translation, performing thorough QA to validate new strings and prevent regressions. This contribution enhanced the project’s internationalization readiness and supported broader user adoption in Catalan-speaking regions. The technical approach emphasized precise Git traceability and CI-friendly commits, reflecting a methodical and quality-driven process in community engagement and localization engineering.
