Worked on enhancing localization for the openwrt/luci repository, focusing on Swedish translations within the LuCI UPnP component. The work involved updating PO files to include new user interface strings related to notification intervals and max-age, as well as maintaining translation metadata by adjusting PO-Revision-Date and Last-Translator fields. Emphasized internationalization and localization best practices to ensure translation accuracy and maintainability, with all changes managed through Weblate for reproducible results. No bugs were addressed during this period, as the primary goal was to improve the Swedish user experience and reduce translation drift by refining the existing localization infrastructure.
