# 🔦 Highlights

# 🚦 Custom Content/Peer Routing Support

Libp2p will now support custom content and peer routers, which will enable users to better customize their DHT experience. The new release allows for using the new Delegated Peer Routing (opens new window) and Delegated Content Routing (opens new window) modules to leverage an external node's DHT instead of or in conjunction with their own. This enables nodes in more resource restricted environments to use an external DHT instead of running their own, which can be very resource intensive.

# 🔌 Relay enabled by default

In an effort to improve default connectivity, circuit relay is now enabled by default. Hop is still disabled by default to prevent relaying traffic for other nodes out of the box, as this is expensive for the node. By enabling circuit relay by default, nodes will now be able to accept and dial to other circuit relay nodes. This improves a nodes default ability to communicate in isolated environments.

# 🤖 State Machine

Libp2p is now a state machine. When starting and stopping the node you can now listen for the stop and start events. Libp2p also exposes a new method, dialFSM, which calls back with a Connection State Machine (opens new window). This gives users the ability to listen to more events on individual connections. You can find out more about these events in libp2p-switch readme (opens new window).

# 🏗 API Changes

  • Added method dialFSM(peer, protocol, callback) which allows users to hook into more connection level activity. You can read more about it in the readme (opens new window).
  • Libp2p now emits start and stop events on node start and stop respectively.
    • Callbacks for .start() and .stop() are now optional. You can instead listen to the error, start, and stop events.
