 <<<<<<< HEAD
 - WhatsApp/reconnect: preserve the last inbound timestamp across reconnect attempts so the watchdog can still recycle linked-but-dead listeners after a restart instead of leaving them stuck connected forever.
 - Gateway/network discovery: guard LAN, tailnet, and pairing interface enumeration so WSL2 and restricted hosts degrade to missing-address fallbacks instead of crashing on `uv_interface_addresses` errors. (#44180, #47590)
+- Gateway/bonjour: suppress the non-fatal `@homebridge/ciao` IPv4-loss assertion during interface churn so WiFi/VPN/sleep-wake changes no longer take down the gateway. (#38628, #47159, #52431)
