Koru 0.1.4

Koru for Linux, diagrams and callouts, and a sharper terminal

• Koru's first stable release for Linux, beside Windows and macOS.
• Mermaid diagrams draw in place in your documents, and callouts set a tip, a warning or a key point apart in a tinted box.
• Terminals draw crisper text, pass every key to the program inside, and scroll back from the keyboard.
• Windows has an installer that needs no administrator rights; Koru now updates from its GitHub releases.

Koru 0.1.4 is published on GitHub, for Linux, Windows and macOS together.
Coming from 0.1.3 on Windows or 0.1.2 on a Mac, Koru updates itself to it as
usual. Mac users also get everything in 0.1.3, listed at the end.

Diagrams

A code block in the mermaid language now draws as a diagram: flowcharts,
sequence diagrams and pie charts. Koru draws it itself, with no browser
inside. Type /diagram or /mermaid to start from an example, or paste a
fence from elsewhere. A Notion page with diagrams pastes in with every one of
them.

• Arrow onto a diagram and press Enter, or click the pencil, to edit its
  text. The drawing follows as you type and keeps the last good drawing while
  the text has a mistake, with the line named.
• The bar at the block's corner opens the drawing in a full-window view
  (Ctrl+wheel or pinch to zoom, drag to pan), copies it as a picture, and
  saves it as PNG or SVG.
• Other diagram kinds, such as Gantt charts, stay a code block and say they
  are not drawn yet.

Callouts

Type /callout, or select lines and press Ctrl+Shift+6 (Cmd+Shift+6 on a
Mac), to put them in a
tinted box with an emoji. Lists, links and formatting work inside it; click
the icon to change the emoji and the color. Callouts survive copy and paste
and Markdown export, and arrive from Notion and Evernote imports.

The first callout you write into a workspace makes it read-only for older
Koru builds, so update your other devices to 0.1.4 too.

Writing and tabs

On a Mac, Cmd takes the place of Ctrl in these shortcuts.

• Typing three backticks waits for Space or Enter before it starts a code
  block, so ```mermaid can be typed as well as pasted.
• Code blocks keep their language through copy and paste.
• Ctrl+Shift+T reopens the last closed tab. Keep window on top moves to
  Ctrl+Alt+A.
• Ctrl+, opens Settings with the search box ready.
• Opening a document while an agent tab is active opens a new tab instead of
  replacing the agent.

Terminals

• Sharper text. Terminal text is hinted for the screen, sits on whole
  pixels and keeps its weight at small sizes. The dark theme's background is
  a deeper black.
• Lines that join. Box-drawing characters, the corners, junctions and
  crosses that programs like Claude Code, htop and tree draw with, meet
  exactly, with no gaps between rows.
• Every key arrives. Home, End, Page Up, Page Down, Insert, Delete and F1
  to F24 reach the program running in the terminal, and Ctrl+Space sends
  what terminal programs expect.
• Scrolling back from the keyboard. Shift+Page Up and Shift+Page Down
  scroll through the output, and Shift+Home and Shift+End go to its top and
  bottom. A full-screen program, such as an editor, gets those keys itself.
  Ctrl+End brings the view back to the newest output.
• Every visible terminal has its own connection, so two terminals draw at
  once. A terminal tab's menu sets its own theme and font, from every font
  installed, and can end its session.
• When Koru's background service restarts under a running window, each
  terminal tab offers Resume or Start new instead of closing.

Agents

• Agent tabs get Koru's own tools, without changing your agent's
  configuration.
• Koru notices when an installed coding-agent CLI is out of date and offers
  a card that runs its updater.
• Codex (Embedded) is gone from the new tab's Agents menu. Codex is still
  there, run in a terminal.

Linux

This is Koru's first stable release for Linux (x86_64). Download the
linux-x86_64.tar.gz archive and extract it into a folder of its own, since
it has no top-level folder, for example ~/koru. Then run ./koru from that
folder.

• koru.desktop in the folder gives Koru an entry in the app list and its
  own icon in the dock. The commands to copy it are at the top of the file.
• The tray icon has the same menu as on Windows and macOS. Closing the
  window keeps Koru in the tray when your desktop shows tray icons (KDE, or
  GNOME with the AppIndicator extension); without one, closing quits.
• Koru finds, checks and installs its own updates. It verifies each one's
  signature first, and goes back to the previous build if the new one fails
  to start.

Windows

The download now includes an installer, setup.exe, beside the zip.

• It installs Koru into your own programs folder
  (%LOCALAPPDATA%\Programs\Koru), or another empty folder you choose,
  without asking for administrator rights. It adds Start menu and desktop
  shortcuts and lists Koru under Settings → Apps.
• Uninstalling from Settings → Apps closes Koru and removes the program, its
  shortcuts, koru:// links and start-at-sign-in. Your workspaces stay.
  Before it starts, it asks why you are leaving. That is optional: leave the
  box empty and nothing is sent.
• If you already run Koru from the zip, you don't need the installer: that
  copy updates itself. The installer is English only for now.

macOS

• Switching between light and dark theme redraws every window straight
  away.
• New in 0.1.3, for Macs coming from 0.1.2: Welcome shows the command that
  connects an MCP client to Koru and copies it in one click; Run an agent
  in a terminal opens the list of coding agents; rows with nothing ready
  behind them are hidden; Koru no longer asks about usage data on first
  start, and shares none unless you turn it on in Settings → System →
  Privacy; and opening Koru from the disk image while an older copy sits in
  Applications asks to replace it instead of opening the old one.

Everything else

• In the tray, Quit now stays quit. Before, an open window started Koru's
  background service again straight away.
• Copy link code, when linking a device, copies only the code, without the
  https://koru.do/link-device# in front. The QR code is unchanged, and a
  code copied either way is accepted.

• Linux runs as an X11 app (XWayland on Wayland desktops); text may look soft at fractional scaling. Dictation is not available on Linux yet.
• Windows is not code-signed yet — SmartScreen asks before the first run, and reminders show no notifications.
