April 2026 monthly summary for linuxdeepin/dde-control-center focusing on UI stability improvements and bug fixes in RegionFormatDialog (date/time settings). The primary deliverable was fixing label overlap and implementing text elision to ensure readability across languages and screen sizes. These changes enhance user experience by preventing data compression of left labels and truncating long date/time texts with proper ellipsis and right alignment, improving consistency with design guidelines and accessibility considerations.

March 2026 monthly performance summary across linuxdeepin/dde-shell, linuxdeepin/dtkdeclarative, linuxdeepin/dde-control-center, and linuxdeepin/dde-launchpad. Key features delivered include Notifications Performance Optimization (WAL mode, tuned SQLite) to reduce blocking during high-frequency updates, Tooltip for truncated display names on touchscreen displays to improve readability, and Display order preservation during resolution changes to maintain user layouts. Major bugs fixed improved notification panel rendering (delegate visibility after collapse) and tightened visual fidelity with tray icons and display ordering. Overall impact: higher notification throughput, clearer UI visuals, and more consistent behavior across devices, contributing to better user experience and stability. Technologies demonstrated: SQLite configuration, Qt Widgets rendering alignment and layout strategies, icon scaling adjustments, tooltip integration, and cross-repo UI polish.

February 2026 monthly summary (2026-02) for linuxdeepin repositories: dde-control-center, dde-file-manager, and dde-shell. Focused on delivering user-visible features, reliability improvements, and clear feedback to users. Key achievements span UX polish, robustness in file transfers, and accessibility/high-DPI rendering. Key features delivered: - dde-control-center: Scrollbar fade-in to prevent ghosting during page transitions and declarative binding to improve lifecycle management. Also, enhanced theme selector navigation via layered event handling for touchpad and mouse interactions. - dde-shell: Notification Center usability improvements including keyboard navigation and focus management, plus higher-contrast/high-DPI text rendering for clearer font strokes. - dde-file-manager: Bluetooth transfer improvements with precise user feedback for long filenames (user-visible error: The filename is too long). Major bugs fixed: - Cursor style bug: Cursor did not update after theme switch; fixed by adding a MouseArea with a default cursor shape to ensure consistent cursor behavior across the app (commit 1b02d0344c94dd58f6742998aa944035a0aff54d). - Bluetooth long filename transfer failure messaging: When a Bluetooth transfer fails due to a filename exceeding 255 characters, shows a clear user-facing error (The filename is too long) instead of a generic message (commit 556accd08f1423fcf5ba3a070e062874698a0c7a). - ListView refresh after collapsing app notifications: Emit layoutChanged to force complete refresh and render displaced items correctly (commit d8cf237523ba262c5274c974af6544f6ee1c6d67). Overall impact and accomplishments: - Substantial improvement to user experience through reduced visual artifacts, clearer error messaging, and more robust navigation across input devices. - Reliability gains from explicit UI refresh signaling and declarative lifecycle management, resulting in smoother transitions and fewer render issues. - Cross-repo collaboration demonstrated by consistent UI/UX improvements and consistent feedback mechanisms, contributing to a more polished product. Technologies/skills demonstrated: - Qt/QML UI patterns: MouseArea, ListView, layered event handling, and explicit focus management. - High-DPI rendering and text rendering improvements for 4K/150% scaling. - Declarative bindings and layout management to reduce lifecycle edge cases and improve stability. - Robust error handling and user feedback in Bluetooth transfers.

January 2026 monthly summary: Stabilized development/testing workflows and improved user experience by delivering a targeted config change and a UI bug fix, with clear commit traceability for future QA and maintenance across dde-file-manager and dde-shell.

In December 2025, linuxdeepin/dde-file-manager delivered a major push in reliability, security, and upgrade robustness. Expanded comprehensive unit test suites across core plugins and dfm-base components to catch edge cases and prevent regressions, enabling safer future changes. Centralized upgrade path configuration in the base UpgradeUnit to protect user configurations during upgrades and improve maintainability. Implemented systemd service files and hardening configurations for disk encryption, mount control, and share control services to strengthen security. Also fixed a critical bug where upgrade units could delete user configuration during upgrades, reducing upgrade risk and support overhead.

Month 2025-11: Focused on strengthening code quality and long-term stability of the linuxdeepin/dde-file-manager plugin ecosystem by delivering comprehensive unit test coverage across core plugins (property dialog, trash, and trashcore). Implemented and validated tests for lifecycle, event handling, view/registration, UI dialog management, and core utilities, with mocks to isolate components. This work is backed by three new test suites with commits b3f251e63edd9072a318cad207f16e025f3d7724, c8cfa4072c0f7f0fad1f36f85ddc4a0031b058a7, and 9a0ddc39d38a3503555ba7066943cbbce32d43cd, plus a repository-wide .gitignore update for AI workflow configs (.spec-workflow/). No explicit bug fixes were recorded this month; the primary value comes from improved reliability and regression protection.
