Today, a fresh edition of the Lightning Network Daemon (LND), version 0.19.2, has been unveiled. This enhancement emphasizes chiefly on bug remedies and performance enhancements.
Notable fixes comprise a bug that led to overlooked payment confirmations, a rare issue that could cause the node to freeze during initiation, and a memory leak that resulted in the software consuming more resources over time. It also resolves crashes that could occur when the node was initializing under certain conditions or managing backups.
The release incorporates an optional migration aimed at diminishing the size of the “decayed log database” (sphinxreplay.db), assisting in reducing disk and memory consumption. This cleanup occurs automatically unless disabled in the settings.
“The migration is optional but enabled by default,” indicated the release notes. “If you face difficulties, you may opt-out of the migration by setting no-gc-decayed-log=true in the configuration. This migration does not hinder reverting to earlier v0.19.x-beta versions.”
Further modifications include enhanced management of peer-to-peer (P2P) connections, improved monitoring of payments in logs, and more precise fee calculations. The update also boosts compatibility with test networks and incorporates minor updates to command line tools (lncli).
Subsequent enhancements encompass improved connection management, refined aux traffic shaping, and updates to the RPC interface for smoother debugging. The Lightning Seed service now accommodates testnet4 and signet, facilitating peer discovery for novice nodes.
The update was constructed using go1.23.9 and enables others to validate that the published files are consistent with the original source code. Docker users can also execute a script to verify the installation prior to launching the container.
The release can be confirmed using PGP signatures and OpenTimestamps to ensure it hasn’t been altered. Complete details and guidelines are accessible here.
