Raw

Version 0.3.0 (2019-01-30)

  • Removed the topology module and everything it contained, including the Topology trait.
  • Added libp2p-noise that supports Noise handshakes, as an alternative to libp2p-secio.
  • Updated ring to version 0.14.
  • Creating a Swarm now expects the PeerId of the local node, instead of a Topology.
  • Added NetworkBehaviour::addresses_of_peer that returns the addresses a NetworkBehaviour knows about a given peer. This exists as a replacement for the topology.
  • The Kademlia and Mdns behaviours now report and store the list of addresses they discover.
  • You must now call Floodsub::add_node_to_partial_view() and Floodsub::remove_node_from_partial_view to add/remove nodes from the list of nodes that floodsub must send messages to.
  • Added NetworkBehaviour::inject_dial_failure that is called when we fail to dial an address.
  • ProtocolsHandler::connection_keep_alive() now returns a KeepAlive enum that provides more fine grained control.
  • The NodeHandlerWrapper no longer has a 5 seconds inactivity timeout. This is now handled entirely by ProtocolsHandler::connection_keep_alive().
  • Now properly denying connections incoming from the same PeerId as ours.
  • Added a SwarmBuilder. The incoming_limit method lets you configure the number of simultaneous incoming connections.
  • Removed FloodsubHandler, PingListenHandler and PeriodicPingHandler.
  • The structs in core::nodes are now generic over the PeerId.
  • Added SecioKeypair::ed25519_raw_key().
  • Fix improper connection shutdown in ProtocolsHandler.

Version 0.2.2 (2019-01-14)

  • Fixed improper dependencies versions causing deriving NetworkBehaviour to generate an error.

Version 0.2.1 (2019-01-14)

  • Added the IntoNodeHandler and IntoProtocolsHandler traits, allowing node handlers and protocol handlers to know the PeerId of the node they are interacting with.

Version 0.2 (2019-01-10)

  • The Transport trait now has an Error associated type instead of always using std::io::Error.
  • Merged PeriodicPing and PingListen into one Ping behaviour.
  • Floodsub now generates FloodsubEvents instead of direct floodsub messages.
  • Added ProtocolsHandler::connection_keep_alive. If all the handlers return false, then the connection to the remote node will automatically be gracefully closed after a few seconds.
  • The crate now successfuly compiles for the wasm32-unknown-unknown target.
  • Updated ring to version 0.13.
  • Updated secp256k1 to version 0.12.
  • The enum returned by RawSwarm::peer() can now return LocalNode. This makes it impossible to accidentally attempt to dial the local node.
  • Removed Transport::map_err_dial.
  • Removed the Result from some connection-related methods in the RawSwarm, as they could never error.
  • If a node doesn't respond to pings, we now generate an error on the connection instead of trying to gracefully close it.
