About Yggdrasil Network

The Yggdrasil network is a decentralized, peer-to-peer network that aims to create a more resilient and private internet infrastructure.

What's new in 0.5.15

  • Go 1.26 is now required to build Yggdrasil
  • Changed
  • Upgrade dependencies
  • Admin socket reads now have a 1MB limit and a 10 second timeout
  • getNodeInfo now returns the local node's information when no public key is supplied
  • WebSocket connections now have response header and TLS negotiation timeouts

Fixed

  • Routing algorithm fixes
  • Improve cost calculations for direct peers of the root and peers with stale or incomplete ancestry
  • Reject incomplete or looping ancestry during parent selection, which could result in a disjoint tree
  • Clean up stale bloom filter bits, avoiding unnecessary lookup traffic during topology changes
  • Correctly throttle repeated lookups
  • Low-order and identity point public keys are now rejected
  • QUIC listeners no longer block other incoming connections while waiting for a peer to open a stream, and close connections that do not open a stream within 5 seconds
  • QUIC and secure WebSocket connections now correctly send TLS SNI and honour the ?sni= URI parameter
  • SOCKS proxy connections now honour connection cancellation and timeouts
  • The mobile bindings now apply the GroupPassword, NodeInfo and NodeInfoPrivacy configuration options
  • yggdrasilctl now correctly returns exit code 1 on fatal errors
  • Admin socket requests with null arguments are now handled as empty arguments
  • Invalid listener passwords and priorities are now rejected before opening a listening socket
  • Invalid private key lengths are now rejected at startup instead of causing a panic
  • The -notifyfd option no longer writes to or closes standard output or standard error
  • Persistent multicast read errors no longer cause excessive CPU usage or repeated warning logs
