MDrust v1.2.0 — Major GUI Fixes, Real Fonts & Performance Optimizations

This release focuses on fixing critical GUI bugs, adding real embedded fonts with CJK support, and introducing performance optimizations.

Bug Fixes

  • Fixed TopBar icon loading every frame — the app icon was being decoded from PNG, resized with Lanczos3, and uploaded as a GPU texture at 60 FPS. Now cached as TextureHandle and loaded once.
  • Fixed preview_text cloned every frame — the entire Markdown output (potentially megabytes) was being .clone()-d at 60 FPS. Now only clones on file selection change.
  • Fixed Rendered preview tab showing same as Raw — both tabs displayed monospace text. Now the Rendered tab uses egui_commonmark for real Markdown rendering inside the GUI.
  • Fixed rt.block_on() blocking UI thread — save_all() was called synchronously inside pump_channels, freezing the UI during file saves. Now runs in a background thread.
  • Fixed Runtime::new().unwrap() — replaced with .expect("failed to create tokio runtime") for better panic diagnostics.
  • Fixed Windows console window — added #![windows_subsystem = "windows"] for GUI builds, no more terminal window on launch.
  • Fixed Windows crash on startup — added panic handler with MessageBoxW so errors are shown in a dialog instead of silently crashing.

New Features

  • Embedded professional fonts — Inter (Regular + Bold), JetBrains Mono, and NotoSansCJK are now embedded via include_bytes! and registered through egui::FontDefinitions. CJK characters render correctly out of the box.
  • egui_commonmark integration — the Rendered preview tab now renders real Markdown with headings, bold, italic, lists, code blocks, and links directly in the GUI.

Performance Optimizations

  • blake3 — content-hash cache for skip-identical-file conversion
  • simd-json — SIMD-accelerated JSON parsing where available
  • compact_str — compact string storage for file paths and titles
  • smallvec — stack-allocated small vectors in hot paths
  • ahash — faster hashing throughout the codebase
