# cmux 0.63.0: SSH, Claude Code Teams, oh-my-openagent, Browser Import, Minimal Mode

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


March 28, 2026

### SSH

cmux ssh user@remote creates a workspace for a remote machine. Browser panes route through the remote network so localhost just works. Drag an image into a remote session to upload via scp. Coding agent notifications come home to your local sidebar. Reconnects on drops.

### Claude Code Teams

cmux claude-teams launches Claude Code's experimental teammate mode with one command. It sets up the environment, fakes a tmux session, and translates tmux commands into native cmux splits. Teammates stack vertically in a right column with sidebar metadata and notifications.

### oh-my-openagent

cmux omo integrates oh-my-openagent (formerly oh-my-opencode), which orchestrates specialist agents across Claude, GPT, and Gemini in parallel. Same tmux shim as claude-teams, auto-installs the plugin, notifications route through cmux.

### Browser Profile Import

Import cookies, history, and sessions from Chrome, Arc, Brave, Firefox, Safari, and 20+ browsers. The import wizard detects installed browsers, lets you pick profiles, and injects everything into cmux's browser panes so you're already logged in.

### Minimal Mode

Hide the titlebar for a distraction-free terminal. Controls move to the sidebar and appear on hover. Toggle from the command palette or Settings.

### Custom Commands

Define project-specific actions in cmux.json that launch from the command palette. One file per repo, no global config needed.
