Changelog

Every Readdown release and what changed. Readdown updates itself, so you're always on the latest one.

1.19 October 2026
- A table of contents for long documents: ⌥⌘T or View > Show Table of Contents (thanks @skykeyjoker)
- Back (⌘[) and Forward (⌘]) after following a link within a document (thanks @stormc)
- Window tabs: merge windows into tabs, and with the tab bar showing, new files open as tabs
- Install with Homebrew: brew install --cask nataliarsand/tap/readdown
- Jumping from the table of contents or Find into a folded section opens it; the fold arrow is easier to click and works from the keyboard
- Reduce motion in macOS settings turns off smooth scrolling and animations
- The "file updated" notice appears only when an open file actually changes
1.18.2 October 2026
- Stricter handling of document content in the app and in Quick Look. Security fixes ship on their own, as soon as they're ready.
1.18.1 October 2026
- A small update: safer handling of links in documents
- Updated the built-in updater
1.18 October 2026
- Copy the file's path from the folder button, the File menu, or ⌥⌘C (thanks @troelskn)
- YAML front matter at the top of a file shows as a code block (thanks @troelskn)
- View → Appearance lets you read in Light or Dark regardless of macOS (thanks @csbertran)
- Links to other apps, like codex:// or vscode://, open after a confirmation that names the app (thanks @justin808)
- Holding ⌘ while scrolling no longer zooms; pinch or ⌘+ and ⌘− still do (thanks @max-jardetzky)
- Long labels in Mermaid flowcharts wrap instead of being cut off (thanks @skykeyjoker)
- Header buttons show tooltips with their shortcuts, confirmations appear centred in the header, and links are checked more strictly
1.17 September 2026
- Copy keeps its formatting: paste into Google Docs, Word, or Mail and your headings, lists, tables, and links survive, while plain-text editors still get raw Markdown
- Base64-embedded images (data:image/...) now render instead of showing as raw text (thanks @javafanboy)
- Equations render when you print or export a PDF
- Code blocks sit on a deeper background and long lines wrap instead of hiding off the edge
- Cmd+F reopens the search box with your last search selected (thanks @Christopher-Crawford)
- UTF-32 files open correctly, and closing a window with the red button no longer risks a crash
1.16 July 2026
- Math rendering: inline and block LaTeX equations, fully offline (thanks @adivijaykumar)
- Collapsible headings: fold any section away with the chevron in the margin
- Sharper Markdown: nested and mixed lists, setext (=== / ---) headings, reference-style links and images, and clickable bare URLs
- A link to another local Markdown file now reveals it in Finder, so you can open it from there
- Stronger, safer handling of raw HTML inside documents
1.15 July 2026
- A cleaner reading view with a floating header: the file name and quick actions (copy, find, show in Finder) tuck into the title bar
- Copy the whole document, or any single code block, to the clipboard in one click (code-block copy thanks to @jantomec)
- Optional, anonymous usage stats to guide what gets improved, off unless you opt in
- Opening a file no longer reopens your entire previous session on top of it
- Mermaid diagrams re-theme instantly on light and dark switch, and printing or exporting to PDF from dark mode now comes out light
- Ordered lists keep their starting number, and bold or italic spanning a wrapped line inside a list item now render (thanks to @troelskn)
1.14.1 June 2026
- Heading anchor links now match GitHub's slug convention for headings with stripped punctuation (e.g. # Foo — bar produces foo--bar, not foo-bar) — thanks @ReubenCowell
1.14 June 2026
- Paragraph lines beginning with # followed by a digit no longer freeze the app
- Fenced code blocks inside list items render as code blocks again
- Heading anchor links scroll to the target instead of being silently cancelled

- Mermaid diagrams in dark mode are legible again
- Readdown no longer hangs at launch when the previous session's documents have moved or been deleted
1.13 June 2026
- Code spans render exactly as written — underscores, asterisks, and HTML tags inside backticks stay literal
- Nested bullet lists render correctly
- Markdown files saved with a UTF-8 byte-order mark open cleanly

- Mermaid diagrams use a refreshed theme that reads well in light and dark mode
