Today, a new version of Lightning Network Daemon (LND), version 0.19.2, has been released. This update focuses primarily on bug fixes and performance improvements.
Key fixes include bugs that missed payment confirmation, rare issues that could freeze nodes during startup, and memory leaks that cause the software to use more resources over time. It also fixes crashes that can occur when a node is up in a specific mode or backup process.
This release includes an option migration to reduce the size of the “Attension Log Database” (sphinxReplay.db) to reduce disk and memory usage. This cleanup will run automatically unless it is turned off in the settings.
“Migration is optional, but by default it is turned on,” the release notes said. “If you run into problems, you can opt out of the migration by setting NO-GC-Decayed-Log = True in Config. This migration does not prevent you from being downgraded to the previous v0.19.x-beta version.”
Other changes include better handling of peer-to-peer (P2P) connections, better tracking log payments, and more accurate pricing calculations. This update also improves compatibility with test networks and adds small updates to the Command Line Tool (LNCLI).
Additional improvements include improved connection handling, improved AUX traffic, and updates to the RPC interface, making debugging easier. Lightning Seed Service supports TestNet4 and Signet, making it easier to peer discovery of new nodes.
This update was built using go1.23.9, allowing others to check that the released files match the original source code. Docker users can also run scripts to confirm the installation before starting the container.
This release can be verified using PGP signatures and opertised stamps to ensure that it has not been tampered with. Details and instructions are available here.
