Colour, and more of Markdown. • Documents have colour now: blue headings, coloured bullets and checkboxes, tinted notes and attachments, underlined links, and brighter code highlighting. PDF export keeps the plain look. • More Markdown renders: HTML formatting tags inside text, such as line breaks, superscripts, highlights and collapsible answers; plain web addresses as links; numbered lists that start at any number; character entities like the copyright sign; and names like snake_case_name. YAML front matter at the top of a file is hidden. • Safer saving: ticking a box or writing a note only saves if the file is unchanged since you last saw it, so edits made in another app are never overwritten. Anything that couldn't be saved stays on screen for you to copy.

Math now renders, and the app opens again on iOS 18. • LaTeX math is typeset, offline: $…$ for inline formulas and $$…$$ for display equations, the way VS Code and GitHub show them. Prices like $5 stay plain text. • Fixed: on iOS 18 the app could close immediately after launch.

Checklists are now somewhere to work, not just something to read. • Notes: hover any checklist item and add a note. It saves into the file as a plain indented bullet, so every other Markdown tool still reads it. • Attachments (Mac): drag a file onto a checklist item to attach it. Click the chip to open that file again. • Clickable file references (Mac): a path written in a code span opens in your editor. • Path bar (Mac): copy the document's path, or reveal it in the Finder. • Live reload is steadier. iPhone and iPad also gain the interactive checkboxes and notes that the Mac version has had.
