+
+### Features
+
+- `Udp.*`: polled IPv4 datagrams - the transport under a game's own netcode. `Udp.open(port)`
+  binds a non-blocking socket (port 0 picks one, `Udp.port` says which), `Udp.send` sends one
+  datagram to an address and port, and `Udp.recv` drains what arrived without ever blocking;
+  `Udp.from_ip` / `Udp.from_port` name the sender. `Udp.ip` / `Udp.ip_text` convert addresses,
+  `Udp.resolve` looks a host name up and `Udp.local_ip` is the address a player on the same
+  network would dial. BSD sockets on macOS (`runtime/native/udp.ll`), Winsock on Windows
+  (`udp_win.ll`, linked with ws2_32), linked only into a program that uses `Udp.*`.
