0.20.0 finishes the link module, and adds the one thing this app could not see: what is running on your own Mac.
Alerts
Netfox can now tell you when a server is still running on this Mac after the shell or agent that started it has gone — the dev server a test run left behind. It reports only the ones bound to the loopback address, which the network scan structurally cannot reach, so nothing else in the app would ever have found them.
It waits fifteen minutes from the moment the process was left behind, not from when the server started, so closing a terminal on something you have been using all afternoon does not set it off. One alert per listener, not one per check, and a listener you deal with and abandon again is a new alert rather than a repeat. Off by default, under Alerts.
Link
On a Mac holding a cable and a radio at once, the round trip to your router is now measured on each link instead of once and labelled. Every card carries its own number, so a slow radio is no longer hidden behind a fast wire — which is exactly the number you were after if the Wi-Fi is the thing you are worried about. On a Mac with one link nothing changes.
Fixes
The weak-signal warning no longer flickers. On a radio sitting near the threshold — the radio the warning exists for — it used to appear and vanish every couple of seconds, because the reading wanders a decibel either way and the whole card changed height each time. It now turns on at once and stays until the link genuinely holds above the line, on a row that never changes height.
That row also gained the info button the rest of the app uses, so the explanation of the threshold is one click away instead of hidden in a hover.
The Alerts inbox header counted every alert as a new device; it now says what it means. And a listener check could, on a Mac with other people's processes on it, hang instead of returning.
