 ### 🔦 Highlights
 
+#### WebRTC-Direct Transport enabled by default
+
+Kubo now ships with `/udp/4002/webrtc-direct` listener enabled by default.
+
+WebRTC Direct complements existing `/wss` (Secure WebSockets) and `/webtransport` transports. Unlike `/wss`, which requires a domain name and a CA-issued TLS certificate, WebRTC Direct works with IPs and can be enabled by default on all Kubo nodes.
+
+Learn more: [`Swarm.Transports.Network.WebRTCDirect`](https://github.com/ipfs/kubo/blob/master/docs/config.md#swarmtransportsnetworkwebrtcdirect)
+
 #### Automated `ipfs version check`
 
 Kubo now performs privacy-preserving version checks using the [libp2p identify protocol](https://github.com/libp2p/specs/blob/master/identify/README.md) on peers detected by the Amino DHT client.

+#### `Swarm.Transports.Network.WebRTCDirect`
 
 [WebRTC Direct](https://github.com/libp2p/specs/blob/master/webrtc/webrtc-direct.md)
 is a transport protocol that provides another way for browsers to
 connect to the rest of the libp2p network. WebRTC Direct allows for browser
 nodes to connect to other nodes without special configuration, such as TLS
 certificates. This can be useful for browser nodes that do not yet support
-[WebTransport](https://blog.libp2p.io/2022-12-19-libp2p-webtransport/).
+[WebTransport](https://blog.libp2p.io/2022-12-19-libp2p-webtransport/),
+which is still relatively new and has [known issues](https://github.com/libp2p/js-libp2p/issues/2572).
 
 Enabling this transport allows Kubo node to act on `/udp/4002/webrtc-direct`
 listeners defined in `Addresses.Swarm`, `Addresses.Announce` or
-`Addresses.AppendAnnounce`. At the moment, WebRTC Direct doesn't support listening on the same port as a QUIC or WebTransport listener
+`Addresses.AppendAnnounce`.
+
+> [!IMPORTANT]
+> At the moment, WebRTC Direct doesn't support listening on the same port as a QUIC or WebTransport listener, and Kubo uses 4002 for it.
