Sep 1, 2025September 2025 (UNIkeEN/SJMCL) focused on reliability, localization, and UX improvements. Key backend enhancement expanded asset whitelist to include all database file types, reducing asset processing failures and streamlining backend validation. Frontend improvements added multilingual resource-aware download filenames, improving file organization for multilingual assets. Localization and performance were boosted with zh-Hans translations for mod names and descriptions, plus concurrent translation requests and caching to speed up mod info display. UX refinement automated save on blur for editable components, removing unnecessary explicit save actions and tightening cancellation behavior. These changes delivered measurable business value through fewer backend failures, faster UI responsiveness, improved multilingual support, and safer editing workflows.
