During July 2025, the dde-file-manager project delivered key features to enhance localization, UI reliability, stability, and release readiness. Notable work includes localization and authentication messaging improvements across zh_HK/zh_TW translations, with clearer host/IP prompts and improved translation handling across languages. UI/UX refinements include dynamic header view resizing on resize events and Qt6-ready media playback with explicit QAudioOutput handling in the media preview feature. Stability and memory management improvements reduced resource leaks and improved lifecycle handling of workers, dialogs, and menus, along with simplified timer management. Release notes maintenance was performed for versions 6.5.76 and 6.5.77, including version bumps and bug-fix notes to streamline future deployments. These efforts collectively improve user perception, cross-language usability, and release confidence, translating to faster feature delivery and more robust product stability.
