Arthur Panckoucke enhanced the French localization of the Grist Client in the gristlabs/grist-core repository, focusing on improving translation coverage and user experience for French-speaking users. Using Weblate as the primary translation management tool, Arthur increased coverage from 96.0% to 97.7% by delivering and validating new translations, ensuring seamless integration into the client. The work centered on localization and translation management, with careful attention to code hygiene and workflow validation. No major bugs were addressed during this period, as the primary goal was to expand internationalization support and maintain stability while preparing the product for a broader market.
