# cmux 0.62.0: Markdown Viewer, Browser Find, Vi Copy Mode, and Localization

[ Changelog](https://cmux.com/docs/changelog)


March 12, 2026

### Markdown Viewer

Open Markdown files in their own panel and keep them live with file watching. Notes, READMEs, and docs refresh automatically as the file changes on disk.

### Find in Browser

Browser panels now support Cmd+F with inline find controls, so you can search long docs, dashboards, and issue threads without leaving cmux.

### Vi Copy Mode

Terminal scrollback now has a keyboard copy mode with vi-style navigation, making it much easier to inspect and copy from large output buffers.

### Custom Notification Sounds

Choose from bundled sounds or pick your own audio file so background task notifications are easier to notice and easier to personalize.

### Expanded Localization

cmux now includes Japanese plus 16 additional languages, and a per-app language override lets you change the UI language without changing macOS system settings.
