This is a minor release focusing on native OS integration, major memory reduction, and print pipeline reliability.

Summary

• System Tray Support: On Windows, closing the window now keeps Feather MD running in the background. This ensures you do not lose background tasks.
• Lower Memory Footprint: By loading heavy math/diagram libraries on-demand, disabling unused GPU browser processes, and trimming memory pages when minimized, the app baseline RAM is significantly reduced.
• Reliable PDF Exports: Closing the app immediately after printing will no longer result in broken, 0-byte PDF files. The application now prompts you and waits for the PDF compilation to complete.
• Open Files in Existing Window: Launching another file while the app is already open will now open it directly inside the running window instead of launching a duplicate process.
• Live Updater Progress: The auto-updater window now displays a live downloading percentage showing the real progress of the download.
• Flexible Recent Files list: You can now remove individual items from your recent files list or clear the entire history.

Details

• System Tray Orchestration: Built native support in [lib.rs](file:///e:/project/featherMD/src-tauri/src/lib.rs) using Tauri TrayIconBuilder and wired live menu updates, window hide/show behaviors, and context actions. Synchronized state checking in [window.js](file:///e:/project/featherMD/src/platform/window.js) via [isTrayActive](file:///e:/project/featherMD/src/platform/window.js#L40) so the frontend fails safe to standard exit on platforms without tray support.
• Working Set Trimming: Implemented COM interface query in Rust to access ICoreWebView2_19::SetMemoryUsageTargetLevel and set the target level to low when hiding the window.
• Resource Reductions: Excluded GPU rendering and auxiliary browser features (such as msWebOOUI, msPdfOOUI, and msSmartScreenProtection) from [tauri.conf.json](file:///e:/project/featherMD/src-tauri/tauri.conf.json). Configured opt-level "s", Link-Time Optimization (LTO), single-codegen-unit builds, and aborted panics in release profiles inside [Cargo.toml](file:///e:/project/featherMD/src-tauri/Cargo.toml).
• On-Demand Math and Diagram Rendering: Extracted math and diagram examples from [welcome.js](file:///e:/project/featherMD/src/core/welcome.js) and split them into a separate template loaded only on user request, avoiding cold-start import overhead.
• Compiling PDF Overlay: Integrated a custom print-status checking loop inside [main.js](file:///e:/project/featherMD/src/main.js) using the window.__FEATHER_PRINTING__ flag. Intercepted close requests to display a #print-overlay spinner in [index.html](file:///e:/project/featherMD/index.html), delaying the window teardown until compile time completes.
• Asset Protocol Relocation: Configured local image path rewriting in [preview.js](file:///e:/project/featherMD/src/preview/preview.js) to route absolute, relative, and file:// paths through Tauri's convertFileSrc helper.
• Single-Instance Locks: Enforced a single application instance check via tauri-plugin-single-instance. Wired launch arguments to be captured and sent to the active window via the open-file-from-args event.
• Editor Transaction Identification: Replaced global boolean flags with compartment-level transaction annotations using CodeMirror 6 to distinguish programmatic content updates from user edits inside [editor.js](file:///e:/project/featherMD/src/editor/editor.js).
• Test Alignment: Updated Vitest test files [html.test.js](file:///e:/project/featherMD/tests/html.test.js), [performance.bench.js](file:///e:/project/featherMD/tests/performance.bench.js), and [toolbar.test.js](file:///e:/project/featherMD/tests/ui/toolbar.test.js) to support the new menu entries, correct font classes, and execute authentic regex stripping benchmarks.
