v0.16.0

We're happy to announce go-libp2p v0.16.0. This is a big release, which adds support for the circuit v2 protocol, paving the way to decentralized hole punching.

Running a circuit v1 relay turned out to be very expensive, which is why only a few nodes could afford to act as a relay. Circuit v2 changes this dramatically: By introducing the concept of relay reservations (limiting the number of nodes connected to a relay at any given point), as well as connection limits (limiting the amount of data and the duration of relayed connections), every node on the network will be able to afford running the relay service.
When circuit v2 relay service is enabled (using the EnableRelayService option), AutoNAT enables the relay v2 service if the node is publicly reachable. Note that currently, AutoRelay does not yet automatically discover relay v2 nodes. This will be added in a future libp2p release very soon. In this release, it is possible to configure known relay servers using the StaticRelays configuration option.

Features

Breaking Changes

  • The context.Context in the host constructor (libp2p.New) was removed (#1190). Use Host.Close() to shut down a host.
  • Remove support for relays running the circuitv1 protocol.

Fixes

  • Fix non-ASCII mDNS peer names (#1222).

Release v0.14.2

This is an optional bug-fix release fixing a bug in the mock-network testing framework. This bug did not affect libp2p itself.

Bug: Identifying a connection would sometimes fail because identify would run before both peers "knew" about the connection.

Release v0.14.1

This release fixes a spec-breaking change to yamux (libp2p/go-libp2p-yamux#36) that could reliably lead to random stream resets.

The bug was introduced in go-libp2p 0.14.0.

Release v0.14.0

We're happy to announce go-libp2p 0.14.0. This release introduces a few long awaited features, fixes a few bugs, and includes progress towards NAT hole punching.

Custom DNS Resolvers

You can now pass a custom DNS resolver through the MultiaddrResolver option. This can be used to add support for DoH, custom TLDs (e.g., .eth), etc.

TCP Simultaneous Open

Adds initial support for TCP Simultaneous Open. If two peers open a TCP connection to each other at the same time using the same set of ports, they'll end up with a single TCP connection. Previously, go-libp2p would treat this as an error and disconnect. Now the connection succeeds. In the next libp2p release, this will be used to enable hole-punching for NAT traversal.

Improved Stream Multiplexer (Yamux) Performance

Yamux now uses variable sized receive windows to improve performance on high-latency, high-bandwidth connections.

Optimized Noise Read Throughput

The Noise security transport now buffers reads, reducing syscalls and significantly improving throughput.

v0.13.0

v0.13.0 introduces a BREAKING interface change: MuxedConn.OpenStream and Conn.NewStream now both take a context.Context. This allows stream multiplexer implementations to unblock OpenStream when requested to do so.

Many stream multiplexers implement some kind of limit on how many streams can be opened at any given moment. This is a useful DoS protection against a peer that would open an unlimited number of streams. That means that opening a new stream might block if it's not possible to open a new stream at that moment.

Upgrade Path

Although breaking, this change is expected to cause little breakage in practice: Host.NewStream already takes a context.Context, which is now passed down to the stream multiplexer's OpenStream method. Only when using Conn.NewStream it will be necessary to add a context to that call.
