v3.9.0 for Linux (pre-release) — AppImage

Pre-release for Linux testing. Not the Latest release, and not offered to macOS or Windows users.

This is the same v3.9.0 build, packaged as an AppImage. It is here so it can be tried on a real desktop before Linux is promoted to a normal release.

What to check

• The app opens its own window (not a browser tab).
• It asks you to connect intervals.icu on first run.
• It serves on 127.0.0.1:22400. If something else already holds that port, Domestique moves to 21055 or 26214 on its own and remembers the choice — you should never have to configure it.

If you saw another program's page in earlier builds

That was the bug this fixes: any server answering on port 8080 was treated as Domestique, so the window opened onto whatever was there. To confirm what it was on your machine:

ss -ltnp | grep 8080

Running it

chmod +x Domestique-v3.9.0-x86_64.AppImage
./Domestique-v3.9.0-x86_64.AppImage

If it fails to start, ~/.domestique/startup_crash.txt will say why — that file is worth attaching to any report.
