The fifth Bi-weekly Technical Progress Report in 2025 has been released. This edition comprehensively reviews the work progress made by deepin technical teams over the past two weeks, while also outlining work plans for the upcoming two weeks.
This report aims to provide comprehensive updates for all enthusiasts and followers of deepin, enabling our community to better follow the system's development and actively participate in its evolution. For any feedback or suggestions, feel free to post at Deepin Community Forum.

DDE(deepin Desktop Environment)

Progress

  • Integrated the QML-based Control Center with the internationalization (i18n) translation platform.
  • Fixed an issue where Launcher app names might display in English instead of the target language in certain locales.
  • Adjusted styling for OSD and session-shell components.
  • Removed Qt5 dependencies for components like the Control Center.
  • Refactored the system update component into modular logic (now maintained under the deepin-update-ui module), decoupling it from the Control Center project.
  • Performed defect fixes for Control Center, Launcher, Taskbar, and other components, with select fixes backported to the deepin 23 maintenance branch.

Plans

  • Migrate existing GSettings-dependent projects to DSG DConfig to unify configuration management.
  • Continue feature development for network and system update modules.
  • Expand internationalization coverage across DDE projects (and other applications) by supporting additional languages.
  • Maintain continuous defect resolution for all DDE components.

 

System Development
