Dec 1, 2025December 2025 (2025-12) monthly summary for linuxdeepin/dde-file-manager. Focus this month was expanding search/indexing capabilities, improving the detail view UX, strengthening file operation reliability, and increasing test coverage. Notable work includes enabling ET format indexing, adding UAB thumbnails, introducing Markdown file preview with 5MB limit and relative image paths, and significant indexing optimizations (ancestor_paths, Chinese input delay, and startup vs event collection separation). UI/UX improvements encompass group header spacing adjustments in list/icon views, detail space elastic drag behavior, and unified selection handling across views. Stability and testing improvements include comprehensive dfm-base and file-operations unit tests, improved crash-recovery readiness with index state tracking, and safer test infrastructure to avoid touching user data. These deliverables collectively improve search relevance, file operation reliability, performance, and developer productivity, while reducing log noise in production.

Jul 1, 2025July 2025 (2025-07) monthly summary for linuxdeepin/dde-file-manager: delivered a set of feature and reliability improvements, prioritized data presentation, performance, and testability. Key features include MIME type handling and sorting enhancements with detection optimization, and a Home directory ordering feature that enhances user experience. String comparison improvements were implemented to unify file-name comparisons and improve locale handling. Architectural stability and performance were strengthened via traversal internals cleanup and multi-threading/thread-safety enhancements, laying a solid foundation for responsive behavior under heavy operations. Build and quality automation were modernized with centralized DFMLibraryConfig.cmake, expanded autotests and unit-test configurations, and unified test targets across dfm-base, dfm-extension, and dfm-framework. Release hygiene and platform compatibility were advanced through multiple version bumps (6.5.72 through 6.5.83), Debian changelog updates, and environment/script compatibility fixes (e.g., dfm-open.sh for Deepin 23). These results translate into faster, more predictable file management, reduced maintenance burden, and improved developer productivity.
