# Cairn changelog ## 2.2.1 - 2026-09-08 - Expanded the workspace navigator with keyboard navigation, route-synchronized selection, configurable detail levels, and more predictable workspace cycling. - Added composable pane layouts and remote pane launching, with more reliable working-directory handling for remote workspaces and splits. - Added automatic local port forwarding for remote folders and development servers, including remote HTML preview serving through Cairn's secure host connection. - Added a local developer control API and MCP interface for inspecting and controlling Cairn workspaces, panels, and actions. - Improved live workspace status timing, panel redraws after dock moves, and remote-split probing behavior. - Improved Cairn Remote connection reliability with staged EICE/SSH deadlines and clearer split diagrams for deeply nested layouts. ## 2.2.0 - 2026-09-08 - Improved remote host launching by detecting coding agents through interactive login shells and clearly separating host repair state from ready warm-pool sessions. - Made remote workspace directories host-aware: new launchers default to the remote home directory, remember successful directories per host, and no longer carry a local Mac home path onto Linux hosts. - Made clean remote process exits close their split and the final workspace while preserving reconnect behavior for unexpected SSH or transport failures. - Simplified Remote Hosts management and made helper shutdown more reliable during login-shell startup. - Added a Needs You attention queue to the iOS Remote app, improved split visibility, and accelerated stale-session reconnection. ## 2.1.1 - 2026-09-07 - Improved Quick Agent launcher legibility by automatically choosing dark or light selected-row text and icons for the current accent color and appearance. ## 2.1.0 - 2026-09-07 - Added always-on host load monitoring that pauses speculative terminal warm-up during sustained CPU contention while keeping user-initiated launches responsive. - Expanded Resource Monitor with host-load, runnable-process, and zombie-process detail, plus optional notifications and cleanup of obsolete Cairn helper processes during severe overload. - Made the repeated Control-C/D close guard configurable from the Window menu with 1, 2, 3, and 5 second durations, and fixed bare Control-C/D events so they reliably reach the terminal. - Improved dock responsiveness with targeted panel refreshes, fewer unnecessary layout commits, and cheaper workspace-pill sizing. - Improved large session-history updates and live activity timestamps while reducing blocking Keychain writes and repeated text-processing work. ## 2.0.2 - 2026-09-06 - Added multi-selection to the workspace navigator for opening, forking, and closing several workspaces together. - Added in-app web viewing on iPhone and iPad for links opened from remote terminal sessions, carried through the existing secure host connection. - Improved Cairn Remote with workspace split diagrams, unread activity indicators, more reliable scroll-tail behavior, and safer agent integration isolation. - Improved compact dock layouts for remote hosts, jump hosts, resource monitoring, and activity views, and updated the remote PTY service to v0.2.0. ## 2.0.1 - 2026-09-06 - Added a native Plugins panel for installing, reloading, inspecting, and removing extensions without leaving Cairn. - Added per-plugin capability controls, runtime status, contribution summaries, and actionable discovery errors for invalid plugins. - Added workflow-focused canvas presets for all panels, window management, fleet launch, and fleet monitoring alongside the existing basic layouts. - Improved narrow dock panes by collapsing the panel type chooser to an icon with an accessible tooltip when space is tight. ## 2.0.0 - 2026-09-06 - Redesigned Cairn around a persistent dockable workspace with split and stacked layouts, configurable presets, drag-and-drop panels, keyboard navigation, and dedicated panels for workspaces, live sessions, activity, history, usage, and remote hosts. - Added a scalable remote-fleet control plane with bounded discovery, session catalogs, repair plans, reconnect policies, richer host health summaries, and faster context-aware workspace launches. - Added a process-isolated plugin platform and local developer API with explicit permissions, custom panels, event subscriptions, build monitoring, a Swift command-line client, and a generated developer portal. - Rebuilt session history on SQLite with indexed search, structured activity records, cleaner titles, attachment and machine-payload filtering, and bounded background indexing. - Improved live-session navigation with receiver routing, preserved execution state, process-backed liveness, workspace context menus, configurable navigator sorting, and open-or-fork actions that carry terminal selection context. - Reduced idle and refresh CPU use by eliminating leaked cursor timers, caching process-session scans, bounding transcript work, and avoiding unnecessary full-text-search backfills. - Removed the legacy Project menu and consolidated workspace, browser, and layout controls around the new dock-based workflow. ## 1.5.0 - 2026-09-05 - Added adjustable screen-band layouts and moved Accessibility-based window scanning and placement off the main thread for smoother window management. - Added a system watchdog and expanded the resource monitor with sustained per-process history, launch-aware tracking, and guarded process controls. -

Added immediate failure detection and clearer recovery guidance when jump-host hardening does not complete. - Reapplied current security settings when reusing an existing jump host and refreshed inventory after setup timeouts. ## 1.3.2 - 2026-08-28 - Isolated AWS jump-host resources per Cairn installation so multiple Macs can safely share one AWS account. - Added guided AWS CLI setup, credential verification, and clearer sign-in recovery in Jump Host settings. -
