libp2p

• Raise MSRV to 1.83.0. See PR 5650.

• Add with_connection_timeout on SwarmBuilder to allow configuration of the connection_timeout parameter. See PR 5575.

• Deprecate void crate. See PR 5676.

• Update default for idle-connection-timeout to 10s. See PR 4967.

• Expose swarm builder phase errors. See PR 5726.

• Deprecate ConnectionHandler::{InboundOpenInfo, OutboundOpenInfo} associated type.
  Previously, users could tag pending sub streams with custom data and retrieve the data after the substream has been negotiated. But substreams themselves are completely interchangeable, users should instead track additional data inside ConnectionHandler after negotiation.
  See PR 5242.

<!-- Update to libp2p-core v0.43.0 -->

• Update individual crates.
  • Update to libp2p-metrics 0.15.0.

• Update individual crates.

  • Update to libp2p-kad v0.46.0.
  • Update to libp2p-identify v0.45.0.

• Raise MSRV to 1.73. See PR 5266.

• Implement refactored Transport. See PR 4568.

• Move address_translation from libp2p-core to libp2p-swarm and libp2p-identify. To now get address translation behaviour, i.e. discovery of extern address (candidates) based on connecting to other peers, one needs to use libp2p-identify now. This pertains to you if your nodes can be behind NATs and they aren't aware of their true external address. See PR 4568.

• Use web-time instead of instant. See PR 5347.

• Remove redundant async signature from builder methods. See PR 5468.

• Allow SwarmBuilder::with_bandwidth_metrics after SwarmBuilder::with_websocket. See PR 4937.

• Allow SwarmBuilder::with_quic_config to be called without with_tcp first. See PR 4821.
• Introduce SwarmBuilder::with_dns_config. See PR 4808.

• Raise MSRV to 1.73. See PR 4692.
• Remove deprecated libp2p-wasm-ext. Users should use libp2p-websocket-websys instead. See PR 4694.
• Remove deprecated libp2p-deflate. See issue 4522 for details. See PR 4729.
• Remove deprecated development_transport. Use libp2p::SwarmBuilder instead. See PR 4732.
• Introduce SwarmBuilder::with_bandwidth_metrics exposing Prometheus bandwidth metrics per transport protocol stack and direction (in-/ outbound). Deprecate Transport::with_bandwidth_logging and SwarmBuilder::with_bandwidth_logging in favor of the new SwarmBuilder::with_bandwidth_metrics. See PR 4727.

• Introduce libp2p::websocket_websys module behind websocket-websys feature flag. This supersedes the existing libp2p::wasm_ext module which is now deprecated. See PR 3679.

• Introduce a new libp2p::SwarmBuilder in favor of the now deprecated libp2p::swarm::SwarmBuilder. See libp2p::SwarmBuilder docs on how to use the new builder. Also see PR 4120.

• Update libp2p-identity version to 0.2.6. Under the hood, we feature-flagged libp2p-identity's rand dependency but it is enabled by default when using libp2p. See PR 4349.

• Add libp2p-quic stable release.

• Include gossipsub when compiling for wasm. See PR 4217.

• Add json feature which exposes request_response::json. See PR 4188.

• Add support for UPnP via the IGD protocol. See PR 4156.

• Add libp2p-memory-connection-limits providing memory usage based connection limit configurations. See PR 4281.

• Add libp2p-webtransport-websys providing WebTransport for WASM environments. See PR 4015.

• Raise MSRV to 1.65. See PR 3715.

• Protocol names are now required to be valid UTF8 strings. We delete the ProtocolName trait from libp2p::core and replace it with a requirement for AsRef<str>. At the same time, we introduce StreamProtocol, a newtype in libp2p::swarm. This newtype enforces additional variants like a leading forward-slash. We encourage users to use StreamProtocol when implementing UpgradeInfo. See PR 3746.

• Rename NetworkBehaviour::OutEvent to NetworkBehaviour::ToSwarm, ConnectionHandler::InEvent to ConnectionHandler::FromBehaviour, ConnectionHandler::OutEvent to ConnectionHandler::ToBehaviour. See PR 3848.

• Remove deprecated mplex module. You can still depend on libp2p-mplex directly but we strongly encourage to migrate to yamux. This also removes mplex from the development_transport and tokio_development_transport functions. See PR 3920.

• Remove libp2p-perf protocol. To use libp2p-perf one needs to import it directly. See PR 3990.

• Remove libp2p-quic and libp2p-webrtc protocols. These are in alpha status and should be depended on directly. See PR 4041.

• Deprecate the mplex feature. The recommended baseline stream multiplexer is yamux. See PR 3689.

• Introduce libp2p::connection_limits module. See PR 3386.

• Deprecate the quic and webrtc feature. These two crates are only in alpha state. To properly communicate this to users, we want them to add the dependency directly which makes the alpha version visible. See PR 3580.

• Introduce libp2p::allow_block_list module and deprecate libp2p::Swarm::ban_peer_id. See PR 3590.

• Introduce libp2p::perf module. See PR 3693.

• Depend on libp2p-tls v0.1.0.

• Introduce ed25519 feature. For backwards-compatibility, the ed25519 identity keys are still available without activating this feature. However, going forward, you should explicitly activate it to avoid compile errors going forward. See PR 3350.

• Enable NetworkBehaviours to manage connections. This deprecates NetworkBehaviour::new_handler and NetworkBehaviour::addresses_of_peer. Due to limitations in the Rust compiler, these deprecations may not show up for you, nevertheless they will be removed in a future release. See libp2p-swarm's CHANGELOG for details.

• Count bandwidth at the application level. Previously BandwidthLogging would implement Transport and now implements StreamMuxer (PR 3180).

  • BandwidthLogging::new now requires a 2nd argument: Arc<BandwidthSinks>
  • Remove BandwidthFuture
  • Rename BandwidthConnecLogging to InstrumentedStream

• Remove SimpleProtocol due to being unused. See libp2p::core::upgrade for alternatives. See PR 3191.

• Bump MSRV to 1.65.0.

• Update individual crates.

  • Update to libp2p-dcutr v0.9.0.

  • Update to libp2p-core v0.39.0.

This is a large release. After > 4 years, rust-libp2p ships with an (alpha) QUIC implementation. The necessary TLS logic is extracted into its own crate, and can thus be used detached from QUIC, e.g. on top of TCP as an alternative to Noise. In addition to these two transports, this release adds a third, namely WebRTC (browser-to-server). But that is definitely not it. See below for the many other changes packed into this release.

• Introduce libp2p-tls v0.1.0-alpha. See PR 2945.
• Introduce libp2p-quic v0.7.0-alpha. See PR 2289.
• Introduce libp2p-webrtc v0.4.0-alpha. See PR 2289.
• Remove deprecated features: tcp-tokio, mdns-tokio, dns-tokio, tcp-async-io, mdns-async-io, dns-async-std. See PR 3001.
• Remove NetworkBehaviour macro export from root crate in favor of re-exported macro from libp2p::swarm. Change your import from libp2p::NetworkBehaviour to libp2p::swarm::NetworkBehaviour. See PR 3055.
• Feature-gate NetworkBehaviour macro behind macros feature flag. See PR 3055.

• Remove default features. You need to enable required features explicitly now. As a quick workaround, you may want to use the new full feature which activates all features. See PR 2918.

• Introduce tokio and async-std features and deprecate the following ones:

  • tcp-tokio in favor of tcp + tokio
  • mdns-tokio in favor of mdns + tokio
  • dns-tokio in favor of dns + tokio
  • tcp-async-io in favor of tcp + async-std
  • mdns-async-io in favor of mdns + async-std
