cmux v0.64.11 Release Notes — What's New

Highlights

Workspace groups — select sidebar workspaces and press ⌘⇧G to group them under a collapsible header, with an anchor workspace, drag-to-group, in-group reorder, per-group color/icon, header unread badges, and a cmux workspace-group CLI namespace.
Focus & Recently Closed history — navigate back/forward through recently focused workspaces and windows from the titlebar, and reopen closed surfaces from a searchable history pane.
Agent Hibernation — pause idle agent sessions and restore them on demand to cut background resource use.
Detachable SSH PTY daemon — keeps remote sessions alive across reconnects.
Configurable sidebar and tab bar font sizes, redesigned notifications popover (swipe to dismiss), browser tab mute, Fork Conversation menu, Xcode-style project visualizer pane, and a cmux diff CodeView viewer.
Fixes across file preview, Hermes hooks, split zoom, titlebar controls, Vault resume, and equalize splits.
