During June 2025, Joan Bautista Querol focused on enhancing localization quality for exelearning by delivering a Valencian Localization Enhancement in the exelearning/exelearning repository. He refined Valencian translations by removing tilde characters and adjusting phrases to better reflect regional language norms, directly improving accessibility and user experience for Valencian-speaking users. His approach involved XML string normalization, translation validation, and close collaboration with translators to ensure linguistic accuracy. The work demonstrated practical application of localization and internationalization best practices, with changes tracked via Git. While the project scope was limited to a single feature, the targeted improvements addressed a clear user need.
