  • Lightning Dev Kit, LDK, has published v0.0.111 which includes support for relaying onion messages! Onion messages are messages that don’t use HTLCs and can be sent across the Lightning network by nodes that support the protocol.

  • Prysmatic Labs publishes v3.1.1 which contains a fix for a fork choice bug which could lead to a memory leak and gossip-sub optimization.
