What's New in v2.8.1
🚀 CI/CD & Build System
- GitHub Actions CI/CD: New cross-platform build workflow — automated testing on Python 3.10/3.11/3.12 (ubuntu), PyInstaller packaging on Windows, macOS, and Linux, with per-platform artifact uploads.
- Local Build Script: Added scripts/build.sh for reproducible local builds with auto-download of platform-specific ffmpeg binaries.
- Platform FFmpeg: ffmpeg is now downloaded per-platform at build time instead of bundling a Windows binary — leaner repo, faster clones.
🔒 Security
- Config Separation: Removed config.yaml from version control — local credentials and settings are no longer tracked by git.
- Single Instance Lock: Native single-instance enforcement prevents accidental duplicate launches and session conflicts.
⚡ Core Engine Improvements
- Task Manager Refactoring: New core/task_types.py with unified task definitions (Task, TaskSignals), cross-thread InfoBar communication, better worker thread lifecycle management, and a dedicated Task Queue UI page.
- Telegram Uploader Refactoring: Streamlined upload pipeline with improved error handling, retry logic, and chunked upload support for large files.
- Drag & Drop Support: New drag service — drag files and folders directly into the app to upload.
🔄 Sync Engine Overhaul
- Modular Sync Architecture: Refactored services/sync/ into dedicated modules — base_sync_task.py, directory_sync_task.py, file_sync_task.py, strategies.py, and scheduler.py.
- Smarter Sync: Improved directory comparison with hash-based file deduplication, rename/move detection (avoids re-uploading moved files), and sorted depth-first directory creation for reliable nested folder sync.
- Sync Dashboard: New per-folder sync status cards with real-time progress bars, detailed file/size counts, and status indicators.
🎬 Media & Preview
- Enhanced Preview Flyout: Now supports video playback (Qt Multimedia), audio playback with seek controls, image preview with zoom, and a 100MB preview size limit for performance.
- File Icons: New file type icon system provides visual indicators across the UI.
🎨 UI & UX
- Task Queue Page: New dedicated page for monitoring all background operations (uploads, downloads, syncs) with real-time progress.
- About Page: New polished about page with app info, developer details, core features showcase, license, and open-source acknowledgments.
- File View Stack: Switch between list and grid views, with search result highlighting support.
- Improved Login: Better QR code login flow, session validation, and error recovery.
- Cross-Thread Notifications: InfoBar messages from worker threads are now safely marshalled to the main thread, eliminating UI glitches during background operations.
🌍 Internationalization
- i18n Generator: Updated scripts/gen_i18n.py with improved translation workflow and multi-language TS/QM compilation.
- Translation Coverage: Full UI translation support across 6 languages (zh_CN, English, German, French, Russian, Korean).
📦 Packaging
- Inno Setup Installer: Updated setup.iss for Windows installer with proper startup task handling and clean install/uninstall experience.
- PyInstaller Spec: New CraftCloud.spec with optimized hidden imports, data file collection, and platform-specific binaries.
📝 Documentation
- Updated docs/readme.md and docs/readme-CH.md with latest features, build instructions, and project roadmap.
🧹 Code Quality
- Removed deprecated modules (breadcrumb_widget.py, icon_utils.py, sync_operation_strategy.py, sync_utils.py) merged into the new architecture.
- Database repository layer refactored for consistency and performance.
- pkg_resources compatibility stub for setuptools >= 82.
