#cmux 0.60.0: Tab Context Menu, DevTools, Notification Rings, CJK Input

Tab Context Menu. Right-click any tab in a pane to rename it, close tabs to the left or right, move it to another pane, or create a new terminal or browser tab next to it. You can also zoom a pane to full size and mark tabs as unread.

Tab Context Menu

Browser DevTools. The embedded browser now has full WebKit DevTools. Open them with the standard shortcut and they persist across tab switches. Inspect elements, debug JavaScript, and monitor network requests without leaving cmux.

Browser DevTools

Notification Rings. When a background process sends a notification (like a long build finishing), the terminal pane shows an animated ring so you can spot it at a glance without switching workspaces.

CJK Input. Full IME support for Korean, Chinese, and Japanese. Preedit text renders inline with proper anchoring and sizing, so composing characters works the way you'd expect.

CJK Input

Claude Code. Claude Code integration is now enabled by default. Each workspace gets its own routing context, and agents can read terminal screen contents via the API.
