## Version 1.42 is out

v1.42 is available as a Stable release. It brings several previously separate calculations together: band information, Worked status, NOT-QRV marks, callsign suffixes and frequencies are now used consistently by the user list, the station map, the priority calculation and the external interfaces.

### The highlights

- **Shared band context:** One central band-opportunity calculation feeds the user list, *New bands*, the band-upgrade hint, the Priority Score, the station map and the automatic band selection. The band columns now distinguish `X`, `a`, `B+` and `o`, and 50 and 70 MHz are supported everywhere — from the station settings through to the Win-Test listener.
- **A connection you can trust:** The ON4KST link has been rebuilt around session-scoped connection handling with bounded timeouts, heartbeat detection and controlled reconnect backoff. A compact `LINK` indicator in the main window shows what the connection is actually doing, and the user list no longer disappears after login.
- **Signed and notarized macOS packages:** The DMG files for Apple Silicon and Intel are signed with an Apple Developer ID and notarized by Apple. The first launch now works by double-clicking, without the detour through **Open** in the context menu, and it works offline too.
- **More precise frequencies:** QRG recognition uses a station-specific band context, AirScout and the map path analysis derive realistic per-station frequencies, and the obsolete 430 MHz fallback is now 432 MHz.
