Nearcade has been released in version 3.0.4.

Nearcade is a remote arcade gaming platform that lets players stream and play games together over the internet - as a desktop app (Electron) and an Android app.

This update focuses on stability and performance: game scanning for large Steam libraries now runs in worker threads with caching, the dashboard no longer flickers on navigation, and several memory leaks and crashes have been fixed.

• Background Scanning: Game scanning for large Steam libraries moved to worker threads with 5-minute caching.
• Audio Fallback: Re-enabled timeout with 3-second Python driver activation.
• ViGEmBus Detection: Native driver detection added to the boot script.
• Tampermonkey Rewrite: Bidirectional memory cache for persisting viewer settings.
• Dashboard Flicker: Navigation flicker eliminated through synchronous DOM application.
• New Settings Modal: Stick deadzone slider, rumble, and bandwidth toggles.
• Dynamic Track Swapping: WebRTC track swapping for multi-instance viewer routing.
• Gamepad-Friendly Routing: New instance assignment dropdown for controller-based navigation.
• Input Isolation: bind-evdev support for window-specific instances.
• Bugfixes: Steam Deck icon parsing, requestAnimationFrame memory leak, URL list scroll limit, stopCapture() teardown issues, and fake StorageEvent crashes.
