# cmux 0.64.5: Codex Teams, Menubar Global Search, Markdown Viewer, Feed by Default

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


May 13, 2026

### Codex Teams Subagent Panes

cmux codex-teams now maps Codex's subagent sessions into native cmux panes, the same way claude-teams does for Claude Code. Spawned subagents stack in a right column with sidebar metadata and notifications routed through cmux.

### Menubar Global Search

A new global search command surfaces windows, workspaces, panes, surfaces, and right-sidebar tools from the menu bar so you can jump anywhere without reaching for the sidebar.

### Rewritten Markdown Viewer

The Markdown viewer now uses a webview-based renderer with richer formatting, better selection, and faster scrolling. Thanks @tobi for the contribution.

### Feed on by Default

The Feed is now enabled by default for new and existing users, surfacing notifications, agent events, and workspace activity in one chronological stream.

### Quality-of-life Polish

Open right sidebar tools as panes, workspace cwd inheritance, an unread defer shortcut, iMessage workspace ordering and previews, and right-sidebar CLI parity. Bug fixes for Korean IME arrows, garbled Chinese paste, Metal renderer crashes, terminal portal resize lag, multi-monitor sleep/wake window position, and Cloud VM SSH attach.
