MUTX v1.3.0#

MUTX v1.3.0 is the first release where the product finally behaves like a real operator lane instead of a stack of disconnected demos.

This version turns the macOS app into the primary operator surface, ships a signed and notarized desktop release for both Apple Silicon and Intel Macs, promotes the browser dashboard as a supported stable surface, and adds a public release/download lane so users do not have to guess where the real build lives.

Release highlights#

1. A real desktop operator app#

The macOS app is now a first-class operator surface, not a thin web wrapper.

• a dedicated desktop product model built around four windows:
  • Workspace
  • Sessions
  • Traces
  • Settings
• a native desktop shell with persistent window state, keyboard shortcuts, and route-independent navigation
• a unified operator home that folds setup, runtime posture, diagnostics, and recovery into one surface
• inline machine awareness for local runtime, bridge health, gateway posture, governance status, and assistant/workspace state

The goal of this release was not to make the desktop app look “fancier.” It was to make it usable as the place where an operator actually works.

2. Signed and notarized macOS builds#

v1.3.0 ships a real desktop artifact lane:

• MUTX-1.3.0-macos-arm64.dmg
• MUTX-1.3.0-macos-x64.dmg
• MUTX-1.3.0-macos-arm64.zip
• MUTX-1.3.0-macos-x64.zip
• MUTX-1.3.0-SHA256SUMS.txt

Both DMGs and app bundles are signed, notarized, stapled, and validated before release. The release process now verifies the mounted app inside each DMG instead of trusting packaging output blindly.

3. A real public download and release lane#

This release introduces the missing public distribution surfaces:

• https://mutx.dev/download
• https://mutx.dev/releases
• https://docs.mutx.dev/docs/v1.3

That means:

• the public site has an actual download entry
• release notes live in docs, not only in GitHub metadata
• the GitHub Releases page carries the signed artifacts and checksum file
• Apple Silicon and Intel links are explicit instead of buried behind generic buttons

4. The stable browser operator shell is clearer#

For browser users, app.mutx.dev/dashboard is now the supported stable operator shell for stable routes.

This release also makes the product boundaries more honest:

• the dashboard lane is presented as supported
• the control demo stays reachable, but still explicitly preview
• public surfaces, docs, GitHub release notes, and download links tell the same story

What changed in the product#

Desktop experience#

The desktop app was substantially rebuilt for this release.

Key improvements:

• route-driven desktop churn was replaced with window-state-driven navigation
• pane and tab switches no longer require full route repainting
• bridge/runtime status is surfaced in the desktop shell instead of hidden behind failing boot flows
• setup now runs in-place with clearer state, logs, recovery, and retry paths
• the desktop shell is much better at using fullscreen space instead of collapsing into a narrow web-style center column
• Sessions and Traces now behave like dedicated tools rather than leftover pages inside a browser shell

Download flow#

The release/download path is much simpler:

• /download is the public download entry
• /download/macos/arm64 resolves to the current Apple Silicon release asset
• /download/macos/intel resolves to the current Intel release asset
• /download/macos/release-notes resolves to the versioned docs release note
• /releases gives a public summary of the current shipped desktop build, GitHub tag, checksum asset, and docs note

Runtime and setup posture#

v1.3.0 also improves the actual operator experience around setup and local runtime state:

• setup runs through the desktop lane instead of feeling bolted on
• local bootstrap and browser/cloud auth are represented more clearly
• bridge state semantics are stabilized around healthy, idle, degraded, and stopped
• clean idle exits are no longer shown as hard failures
• desktop runtime inspection, status polling, and recovery actions are much less noisy

Release and validation hardening#

This release closes a lot of “it works on my laptop” gaps in the ship lane.

The release path now includes:

• fail-closed validation for lint, typecheck, build, generated-artifact verification, browser smoke, desktop cockpit smoke, and signed desktop validation
• docs-backed GitHub release notes instead of dumping the root changelog into the release body
• production promotion runbooks and workflow support for Railway
• manual DMG assembly and mounted-app signature verification to prevent malformed DMGs from shipping
• release-facing route and artifact checks that keep the website, docs, GitHub release, and desktop assets aligned

Supported in v1.3.0#

These are the surfaces we consider part of the shipped release:

• mutx.dev
• mutx.dev/download
• mutx.dev/releases
• docs.mutx.dev
• the signed macOS app downloaded from the public release lane
• app.mutx.dev/dashboard for stable browser operator routes
• the CLI install path via curl -fsSL https://mutx.dev/install.sh | bash

Still preview#

These surfaces are still not presented as fully stable in v1.3.0:

• app.mutx.dev/control/*
• preview-labeled dashboard areas that are intentionally outside the stable operator lane
• backend capabilities whose live runtime contract is still gated or incomplete

Upgrade notes#

If you are already using MUTX:

• use the public release lane at mutx.dev/download for the desktop app
• prefer the Apple Silicon build unless you are explicitly on Intel hardware
• treat mutx.dev/releases as the public release summary and GitHub release handoff
• use the browser dashboard for stable hosted routes and the desktop app for the primary local operator flow

There are no new public API contracts you need to adopt for this release. Most of the work in v1.3.0 is product coherence, desktop usability, artifact reliability, and honest surface positioning.

Artifact and release sources#

• Stable dashboard entry: https://app.mutx.dev/dashboard

Closing note#

v1.3.0 is the release where MUTX stops pretending the desktop, download, docs, and dashboard surfaces are somebody else’s problem.

There is still more polish to do, especially around preview surfaces and deeper operator workflows, but this is the first release where the product, the artifact lane, and the public story line up.
