JackMoebius release notes and version history: what changed in each release.

Notable changes to JackMoebius.

Format: Semantic Versioning. Versions 0.x cover the initial development phase (before commercialization).

1.0.0 · 2026-10-02 · first commercial release

JackMoebius is now a commercial product: a 14-day free trial, then a one-time license unlocks it for good, with all updates included. This release also brings a smoother onboarding and UX polish gathered since 0.13.

Added

  • 14-day free trial, then activate a license to keep routing. Activate in JackMate, or with jackmoebius license activate.
  • Guided post-purchase onboarding and a GUI-first activation guide. JackMate (the free JACK patchbay & manager) is installed alongside JackMoebius (optional) and is the recommended way to drive it.

Known limitations

  • Zoom is not compatible. Zoom rejects virtual audio devices on macOS (even via an Aggregate Device), so it is skipped by default. Every other tested app (Microsoft Teams, Audacity, OBS, browsers…) works normally.

0.13.2 · 2026-07-12

Added

  • The bundled command-line tool can report the trial status offline (without a running daemon), so a front-end can show the days remaining at any time.

0.13.1 · 2026-07-12

Internal groundwork for the upcoming trial and license system. No change to how JackMoebius works today; nothing is gated.

0.13.0 · 2026-07-11

Added

  • Signed and notarized by Apple. The installer is code-signed and notarized, so it installs cleanly with no Gatekeeper warnings.
  • The license agreement is shown during installation.

Changed

  • In System Settings ▸ Login Items & Extensions, the background item is now clearly labeled JackMoebius.

0.12.3 · 2026-07-07

Added

  • The daemon and CLI report the running build: a jackmoebius --version banner and a version field in the status reply, so a front-end can display and verify the installed version.
  • Shell completion for the version subcommand.

0.12.2 · 2026-07-07

Added

  • Event-driven routing (step 2): per-process CoreAudio device listeners emit fine-grained routing_changed events, so routing status stays live with no polling.

Fixed

  • Reliable capture eligibility for multi-process apps: apps that play from helper processes (browsers, etc.) are now detected correctly.

0.12.1 · 2026-07-07

Changed

  • The apps table is aligned, and channel ranges are shown compactly (e.g. 10->25).

Fixed

  • The daemon is launched through launchd rather than spawned as a child process (which broke JACK when started from the GUI).

0.12.0 · 2026-07-06

Added

  • Event-driven status (step 1): a persistent subscribe channel over the IPC socket pushes invalidation events (exposure, apps, routing, master, JACK, stopping). A front-end stays in sync without polling and detects a daemon exit instantly.

0.11.3 · 2026-07-02

Added

  • On a routing mismatch, the JACK listings name the device currently in use (current_device / current_device_uid), for a guided message in the GUI, covering both output and input directions.

0.11.2 · 2026-07-02

Added

  • status reports per-direction exposed-box counts (exposed_out / exposed_in) so a front-end can gate its polling.

0.11.1 · 2026-06-26

Added

  • Shell completion for the blacklist subcommand.

Fixed

  • Per-app audio status is aggregated across an app’s helper processes (so a browser playing from a helper reads as active), and listings show friendly names.

0.11.0 · 2026-06-26

Added

  • User blacklist: apps you never want proposed for routing (hidden from add and from the app selector), with CLI management.

0.10.1 · 2026-06-26

Added

  • The master box carries org.jackmoebius.master metadata so a front-end can recognise it.

0.10.0 · 2026-06-25

Added

  • Symmetric apps IPC: independent input/output state per app.
  • Universal driver (Intel + Apple Silicon).

Changed

  • Per-app volume matches macOS’s square-root volume taper.

Fixed

  • The jack_list_in mirror.

0.9.0 · 2026-06-22 · First packaged version

The first formally versioned build, setting the macOS 15 floor.

Changed

  • Set the macOS 15.0 minimum, aligned with JackMate.
  • First version stamp on the driver and the bundle.

Added

  • A login LaunchAgent that hides the internal devices at boot.

0.8.0 · 2026-06-18 · Master, volume & sample rate

Added

  • A master box (on/off) that replaces the plain monitor, with the system default output switched to the JackMoebius output at start.
  • Per-app volume with a lockable cadenas (locked to the master by default).
  • Per-app input/output device-routing status: the foundation for the correctness indicator.
  • Sample-rate matching: the driver follows jackd’s rate, across 12 advertised rates (8 kHz – 192 kHz).
  • A clock-drift diagnostic gauge.

0.7.0 · 2026-06-16 · Bidirectional, per app

Added

  • Bidirectional per-app cards: the daemon now receives from JACK, with a single box wiring both directions for each app, an input-card pool and allocator (add / remove / clear --in), and a masked card lifecycle.
  • App detection on the live CoreAudio process list, unified input/output listings, and --in autocompletion.

Changed

  • The forward device is split into a user-visible output device and a hidden internal tap.
  • JACK-tied visibility: the internal devices are hidden, and capture is gated, while JACK is down.

0.6.0 · 2026-06-13 · Deterministic transport + the reverse device

Added

  • The reverse-path foundations: an input (In) device, a reverse bus with a Feed write point, and a control-plane gate (the bus stays inert until claimed).

Changed

  • Deterministic bus transport: a per-reader alignment delta on the write head removes the timing “anchor lottery” (later measured at ±26 ms per take).

0.5.0 · 2026-06-12 · Lifecycle & latency

Added

  • Daemon lifecycle from the CLI (start / stop / status, clean SIGTERM).
  • Exposure intents persist: boxes revive across daemon restarts.
  • clear chains an implicit remove (unroute, drop the box, free the channels).
  • Bridge latency computed and pushed to the driver, buffer tuning, monitor volume + mute.

0.4.0 · 2026-06-11 · One box per app

Added

  • SlotAllocator: persistent, per-bundle-ID channel reservations (a saved patchbay restores itself).
  • A HAL control plane with app-identity resolution.
  • The IPC server and the jackmoebius CLI.
  • One JACK box per app (localized names, a metadata tag, monitor control) with a lifecycle reconciler: a box is visible if and only if its app is running and exposed.

0.3.0 · 2026-06-11 · Into the JACK graph

Added

  • JackBridge: monitor ports published in the JACK graph through a dlopen-ed libjack; the system mix becomes audible through JACK.
  • A supervised daemon with auto-reconnect to both jackd and coreaudiod, plus latency instrumentation.

0.2.0 · 2026-06-11 · Continuous 64-channel capture

Added

  • The jackmoebiusd daemon (a Swift package) with AudioBridge: continuous 64-channel CoreAudio capture from the driver. Validated with live hot-routing and a 10-minute endurance run.

0.1.0 · 2026-06-10 · The driver

The starting point was a close reading of Stéphane Letz’s note on moving JackRouter to AudioServerPlugin. It lays out the showstoppers that turned the original JackRouter (built on the old AudioHardwarePlugin HAL plug-in, broken since macOS 10.15) into a dead end, and points toward the modern AudioServerPlugIn driver model. JackMoebius doesn’t follow that proposal strictly, but several of its ideas set the direction.

Added

  • The AudioServerPlugIn driver (Rust): a per-app virtual audio device exposing CoreAudio to a userspace plug-in.
  • A 64-channel capture probe and a minimal HAL control tool.
  • End-to-end validation of the full chain on modern macOS.
