Sunshine release v0.21.0 improved system tray support, and it includes desktop notifications for connections. So this application is no longer needed, and will remain in archived state.
Sunshine Connection Notifier is a simple program to send notifications when someone connects/disconnects to/from Sunshine host. Currently works only on Windows (10/11). There is a plan to add support for Linux/macOS.
Download latest installer from releases and launch it.
