Optional autorouters no longer have to ship inside every installer. Settings → Routers lists fab_router, Freerouting, and TraceMaker. Install, cancel, retry, or uninstall from that catalog. Route Cinema uses the same picker.

This landed on main after the published desktop v0.2.146 nightly. The download page will list it with the next public build.

What shipped:

  • checksummed downloads into the per-user data directory, with progress while a package is resolving, downloading, verifying, or extracting;
  • a source-tarball fallback for TraceMaker when a platform binary is missing, marked as source-only until you build it;
  • route_run accepts router=tracemaker and tells you to install if the binary is not ready;
  • uninstalling the saved default router resets routing back to automatic.

New projects still use the automatic routing path: Freerouting by default, fab_router as fallback. TraceMaker is not vendored into the desktop package.

The longer write-up is the field note TraceMaker and the desktop homepage.
