Windows are now independent: opening a file no longer changes the file in your other windows. Open and Go to Home now act on the focused window only. The title bar shows the open file's name, with a draggable proxy icon.

Markdown rendering, rebuilt from the ground up. • Mermaid diagrams inside Markdown — flowcharts, sequence diagrams, and more now render as real diagrams right in your .md files, in the app and in Quick Look. Click any diagram to open it full size with zoom and pan. • Syntax-highlighted code blocks — fenced code now draws as a clean rounded card with a language tag and real syntax colors for 16 languages, including Swift, JSON, YAML, SQL, Python, JavaScript, TypeScript, Go, Rust, and shell. • Sharper typography — inline code chips, quote bars that follow wrapped text, section dividers under headings, true horizontal rules, and images that reflow to fit the window. • Quick Look now matches the app — the spacebar preview uses the exact same renderer, so your Markdown looks identical everywhere on your Mac. • Faster on large documents — rendering happens off the main thread and diagrams are cached, so long files open immediately and stay smooth while you scroll, search, and edit. • Easier CSV navigation — pick a column in the sidebar and the table scrolls right to it, arrow keys step cell to cell, find jumps to matches in off-screen columns, and scroll bars now follow your system setting.

• Mermaid diagrams — render flowcharts, sequence diagrams, and more right in your Markdown and in Quick Look, with pinch-to-zoom, drag-to-pan, syntax highlighting, and light/dark themes. Pro users can author and edit them live. • Synced scrolling — the source editor and preview now scroll together in Markdown split view, so you never lose your place. • Better Markdown — switched to a more robust CommonMark/GFM engine for more accurate formatting, plus a smarter source editor that no longer mangles syntax with smart quotes or autocorrect. • Faster & lighter — optimized text rendering and accelerated CSV parsing for snappier previews of large files. • Polished custom document icons so your files look great in Finder.
