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

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.
