   **Changes and improvements**
 
   - The MASQUE protocol is now the only protocol that can use [Proxy mode](/cloudflare-one/connections/connect-devices/warp/configure-warp/warp-modes/#proxy-mode). If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or switch to the MASQUE protocol. Otherwise, all devices matching the profile will lose connectivity.
+
+  **Known issues**
+  - Devices using WARP client 2025.4.929.0 and up may experience Local Domain Fallback failures if a fallback server has not been configured. To configure a fallback server, refer to [Route traffic to fallback server](/cloudflare-one/connections/connect-devices/warp/configure-warp/route-traffic/local-domains/#route-traffic-to-fallback-server).
