Overall, improved user experience, reduced potential support loads, and demonstrated strong cross-repo collaboration and code quality improvements.

April 2025 performance summary: Across the Linux Deepin desktop stack, we delivered tangible business value through Qt6 migration readiness, UI polish, and stability improvements, while tightening release hygiene to enable faster future iterations. The month focused on removing legacy Qt5 dependencies, hardening theming and UI behavior, consolidating update tooling, and enhancing notification and search UX—all aimed at reducing maintenance risk and improving end-user reliability.

March 2025 monthly summary focusing on delivering robust UI components, reliability improvements, and performance enhancements across multiple modules. Highlights include long filename handling fixes, crash/pointer safety improvements, cross-version Qt6 compatibility, and parallelized rendering/performance work, with release readiness activities.

February 2025 performance highlights focused on strengthening Wayland readiness, theming fidelity, UI robustness, and developer tooling. Implemented cross-repo improvements that deliver a more stable, visually coherent experience across Wayland and non-X11 environments, improved localization, and prepared for a milestone release. The efforts enhanced business value by delivering a consistent UI under modern display servers, reducing visual defects, and enabling faster developer iteration through examples and tooling.

January 2025 performance and stability sprint across linuxdeepin repositories delivered concrete business value through stability hardening, UX consistency, and runtime efficiency. Work spanned six repositories with cross-cutting improvements in Qt6 handling, UI focus management, memory safety, and cross-process environment propagation. The changes reduce crash surfaces, improve perceived responsiveness, and ensure more reliable multi-process behavior in tray, launcher, and shell components.

December 2024 monthly summary across linuxdeepin/dtkdeclarative, linuxdeepin/dde-shell, and felixonmars/treeland. Focused on cross-version Qt compatibility, UI polish, robust notification lifecycle, and secure session management. Business value includes reduced maintenance overhead, improved user experience, and stronger stability across Qt5/Qt6 deployments and multi-seat environments.

November 2024 highlights across linuxdeepin desktop projects: delivered UX improvements and stability enhancements across the desktop stack, with a focus on reliability, security, and performance. Key features include enhanced Notification System UX in dde-shell, lock-screen and power-management improvements on Wayland (ShutdownApplet lockscreen protocol and Treeland UI updates), and docking/UI debugging refinements. Memory safety improvements were implemented in DTK Declarative (appLoaderItem lifecycle and DPalette release) to reduce leaks and crashes. Overall, these efforts improve user experience, system stability, and maintainability, while enabling more robust power and lock-screen workflows.

October 2024: Strengthened stability, usability, and release hygiene across dde-shell, dtkdeclarative, and dde-tray-loader. Key deliverables include: (1) Notification subsystem fixes—ensured first-run DB initialization by creating required directories/files and corrected dynamic notification positioning; (2) Added a user-facing notification bubble limit and desktop visibility control wired through BubbleModel and DConfig; (3) Release/version hygiene—bumped development versions and updated Debian changelogs for dde-shell (1.99.2 to 1.99.3) and dde-tray-loader (1.99.1 to 1.99.2); (4) UI correctness—fixed InWindowBlur render area during window resize by adjusting ProxyRenderTarget size to reflect window changes.
