What's New in Multiplex
1.3.0
August 11, 2026
Multiplex 1.3.0 — run herdr instead of tmux, select text in any pane, and hear from your agents after you've walked away. • Choose a session backend per host. Host Settings → Backend switches between tmux and herdr 0.7.5+: one deck tile per herdr session, its workspaces on the tile's spine, live miniatures, and agent state read from herdr itself. Attaching, merging, detaching, file attachment, shortcut panels, and agent history all work on either backend. • Or show both on one host. Each refresh quietly asks the other multiplexer whether it has sessions; when it does, that host's rail offers to add them, saying what the extra checking costs. Accept and both backends' sessions share one deck, herdr's tiles in a lighter chassis; long-press the offer to stop being asked on this device. Backend is a check selection now — tick tmux, herdr, or both, with a choice of which one new sessions run on — and New Session, the Open Shell and Open Agent Shortcuts, the Host widget, and Add Host → BIND all carry that choice on a host running both. • Long-press or double-tap terminal text — or secondary-click with a mouse or trackpad — for SELECT / SELECT ALL / PASTE right at the gesture. The selection stays inside the pane you pressed on split layouts, a floating bar carries COPY and DONE beside it, and taps stop reaching the remote until you finish. On herdr tabs the block adds MENU, which opens herdr's own pane menu where your finger was. • Keep a host alive after you leave. Host Settings → Monitoring adds a second switch, off by default: that host's sessions and probing survive the extra running time iOS grants a departing app, and iOS can wake Multiplex later to check it again, so an agent finishing while you are elsewhere can still reach you. The timing is iOS's call, and nothing runs in the background for a host you did not switch on. • Agent alerts now reach you about the session you were last looking at — the one most likely to be running an agent, and the one that used to stay silent. Notification permission is asked while Multiplex is on screen instead of riding your first alert. • On iPad, a terminal window wears its own title bar: DECK, the session title, LIVE, A− A+, + TAB, FILE, TMUX, and DETACH on one slim row that matches the key rail at the other end of the pane. • Drag window tabs into the order you want. The File Viewer gains tabs of its own — long-press a file in the tree to open it beside the first — plus ◂ ▸ browse history, and it keeps DIFF selected as you move between changed files. Reading size is yours: A− / A+ on the ▤ tab's rail or a pinch, remembered and applied to every file viewer tab. • Every terminal carries a GUIDE chip, an illustrated field manual of that tab's gestures. • Under mouse reporting each tap now reaches the remote immediately, one click per tap, so a TUI's own double-click lands. Widgets and Shortcuts can launch agents on herdr hosts and into an existing session. Settings → About lists every open-source component in the binary with its full license text. • The agent strip no longer carries STOP: press ESC on the key rail to interrupt a turn. • Rebuilt on UIKit throughout, for steadier typing, scrolling, and window handling.
