v0.36.1

⚠️ Breaking Changes ⚠️

• Conn.NewStream, Network.NewStream and Host.NewStream timeout after 15 seconds, if no deadline is specified on the provided ctx.

🔦 Highlights

AutoNAT v2

• This release ships with an autonat-v2 service. The service allows users to check their rechability for individual addresses.
• For more details of the protocol, refer to the specs:
• BasicHost doesn't use autonat-v2 right now for verifying reachability. Once there are enough autonat-v2 servers in the IPFS network, we will use autonat-v2 to infer the node's reachability, and deprecate autonat-v1.
• AutoNAT v2 is disabled by default. To enable, use the EnableAutoNATV2 option.

WebRTC

WebRTC Direct transport is now Non-Experimental

• /webrtc-direct is now enabled by default.
• We will provide patch releases for any bug fixes or security vulnerabilities in WebRTC just like other transports.

Share listening port with QUIC

• WebRTC Direct nodes, like WebTransport nodes can use the same port as the QUIC transport.

	h, err = libp2p.New(
		libp2p.ListenAddrStrings(
			"/ip4/0.0.0.0/udp/4242/quic-v1",
			"/ip4/0.0.0.0/udp/4242/webrtc-direct"),
	)

• Servers now don't need to open an extra port in their firewalls. This also enables WebRTC Direct nodes to infer their publicly visible address on machines behind a NAT.
