July 2026 monthly summary for linuxdeepin/dde-file-manager: Delivered UX improvements for the file chooser address bar, refined chooser-dialog behavior, and improved error messaging to reduce user confusion. These changes enhance navigation accuracy, prevent accidental saves, and provide clearer feedback for missing paths, contributing to a smoother user experience and reduced support inquiries.

June 2026 monthly summary for linuxdeepin/dde-file-manager focusing on security, reliability, and UX improvements. Delivered security-hardening for TPM-related config handling by replacing a hardcoded temporary path with a dynamically generated directory via mkdtemp, and introduced an RAII-based TempDirHolder to ensure automatic cleanup of sensitive files. Enhanced Vault UI with top-most file dialogs and missing translations to improve accessibility and localization. Stabilized vault operations by moving mount-directory validation and error dialogs from background threads to the main thread, preventing crashes when the directory is non-empty. Improved device watcher reliability by constraining device add/remove updates to loop devices, ensuring encrypted drives are correctly represented in the computer view. All changes contributed to a more secure, stable, and user-friendly file manager with stronger localization support.

May 2026: Delivered security and reliability enhancements for linuxdeepin/dde-file-manager. Implemented SMB feature optimization using memfd for secure data handling and enhanced password reading; fixed UI reliability by switching sidebar throttle timing to a monotonic clock. Achieved improved security, UI responsiveness, and robustness against system time changes, demonstrating strong C++/Qt capabilities and secure I/O design.

April 2026: linuxdeepin/dde-file-manager delivered key File Dialog enhancements and stability fixes, improving UX and reliability across high-DPI displays. Features delivered include persisting last visited directory and high-DPI icon rendering, with last-visited URL saved on accept and a new public saveLastVisitedUrl() method. Fixes cover save-mode filename stability, SMB directory filtering, and high-DPI completer artifact corrections. Impact: faster, more predictable file selection, fewer UI glitches, and DPI-consistent visuals. Technologies demonstrated: C++/Qt DPI handling, devicePixelRatio/F rendering, UI polish, and robust regression fixes.

October 2025 (linuxdeepin/dde-file-manager): Focused on UI reliability for file dialogs and improving vault recovery flow. Delivered a feature to keep file dialogs on top to enhance task continuity, but subsequently reverted the change after feedback to preserve existing window behavior. Fixed vault unlock reliability by bypassing cache to correctly recognize post-recovery status, reducing unlock failures. Overall, these efforts improved user workflow, reduced potential confusion, and strengthened state management across the file manager. Technologies demonstrated include Qt UI hints (Qt::WindowStaysOnTopHint), cache/state handling, and disciplined change management with targeted commits.

July 2025: Delivered four key updates in linuxdeepin/dde-file-manager focused on UI clarity, UX improvements, and localization. Implemented Vault Display Name Consistency, GIF Preview Size Optimization, GTK File Dialog Name Filter Visibility Enhancement, and Localization and Terminology Consistency. These changes improve user understanding, prevent oversized previews, present cleaner external dialogs, and ensure consistent translations across the product.

June 2025 monthly summary for linuxdeepin/dde-file-manager highlighting reliability, security UX, and visual polish. Delivered critical fixes to boot-time and disk-unlock flows, hardened decryption UX under TPM lockout, improved file manager rendering quality, and stabilized sidebar item creation. These changes reduce boot friction, enhance data access security, and uplift UI quality for end users.

Month: 2025-05 — linuxdeepin/dde-file-manager Overview: Focused on stabilizing user experience and strengthening encryption reliability. Delivered two critical bug fixes that remove UI glitches and improve TPM-based disk encryption reliability, reducing user friction and support risk. Key highlights: - Task Widget Hover UI Stability: fixed a hover-related visual error in the task widget by removing a stretch element from the horizontal layout within the conflict widget, resolving the user-facing UI glitch during interaction. Commit: cfcaa09f9ff0dd65b8c9169911443686046747a6. - TPM Disk Encryption Reliability: resolved disk decryption failures with TPM by adding missing libutpm2 dependency, standardizing PCR values to '0,7', and optimizing TPM algorithm retrieval to ensure more reliable encryption/decryption for users. Commit: 2694eb84835ad218af13c8659939540667785ee1. Overall impact: - Improved stability and user experience in task management flows. - Increased reliability of disk encryption/decryption for TPM-based devices, reducing encryption-related support tickets and user-facing failures. Technologies/skills demonstrated: - UI debugging and layout adjustments, dependency management (libutpm2), TPM integration, and secure bootstrapping practices.

April 2025 monthly summary focusing on key accomplishments across linuxdeepin/dde-file-manager and linuxdeepin/dde-shell.
