DDE(deepin Desktop Environment)

Progress

  • Fixed an issue where some components of the Control Center failed to load translations correctly for certain regional languages.
  • Addressed an issue in dde-network-core where some translation resources had empty source text, preventing translation.
  • Resolved an issue in dde-shell where translations for certain regions failed to load correctly, and adjusted the source of text strings for specific positions.
  • Added a taskbar lock feature to prevent accidental dragging, along with a corresponding setting in the Control Center.
  • Optimized the Launcher’s fuzzy search function to improve matching accuracy.
  • Made multiple minor adjustments to the Control Center’s UI and refined UI interaction behaviors.
  • Fixed several defects in other DDE components.

Plans

  • Prioritize defect fixes for maintenance across all DDE components.
  • Prepare for the smooth release of DDE with the official launch of deepin 25.
