   **Changes and improvements**
-
+  - Proxy mode has been enhanced for even faster resolution. Proxy mode now supports SOCKS4, SOCK5, and HTTP CONNECT over an L4 tunnel with custom congestion control optimizations instead of the previous L3 tunnel to the Cloudflare edge. This has more than doubled Proxy mode throughput in lab speed testing, by an order of magnitude in some cases.
   - 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.
