VibeServer 4.1.51 — the Mac can tell you it is out of date, and nobody needs to know what a locator is

Update checking on macOS. It was the only platform with no way to learn it was old — Linux has apt, Android has Play, the Mac had nothing, and a Mac running a public receiver is unattended for months.

A quiet check once a day, on by default and switchable off in Settings. No dialog at launch — a red arrow appears beside the menu-bar icon when there is a newer version, and hovering says which. It checks and tells you; it does not download, install or restart anything.

You no longer need to know what a Maidenhead locator is to list a receiver. The directory requires one, and nothing derived it — so "Town or area" got you a refusal about a field nobody had asked you to understand. Every platform now offers the same three routes in the same words: a device fix where the OS allows it, Work it out for me from a town name everywhere, or typing a locator or coordinates by hand. The lookup happens on your own machine; the server gains no dependency and makes no outbound call.

"Save changes" is now "Apply Changes and Restart VibeServer". Two save buttons said neither what they did, and only one of them drops listeners.
