Noteworthy fixes in this release consist of resolutions to problems that led to missed out on payment verifications, an unusual start-up freeze, and a memory leakage that might cause increased resource intake with time. Additionally, it attends to crashes that might take place under particular functional modes or while handling backups.
The upgrade presents an optional migration function developed to lower the size of the “decayed log database” (sphinxreplay.db), which adds to reduced disk and memory usage. This optimization runs instantly unless handicapped in the setup settings.
According to the release notes, “The migration is optional but turned on by default. Should any difficulties arise, users may disable the migration by setting no-gc-decayed-log=true in the configuration. This migration allows for downgrading to previous v0.19.x-beta versions.”
Additional enhancements make up enhanced management of peer-to-peer (P2P) connections, improved tracking of payment logs, and more exact cost computations. The upgrade also improves compatibility with test networks and presents small enhancements to command line tools (lncli).
Among the noteworthy enhancements are improved connection handling, much better auxiliary traffic shaping, and updates to the RPC user interface, which assist in more simple debugging. Furthermore, the Lightning Seed service now supports testnet4 and signet, streamlining peer discovery for emerging nodes.
This release was built utilizing go1.23.9, allowing users to validate that the launched files refer the initial source code. Users running with Docker can perform a script to verify the setup prior to releasing the container.
Verification of the release can be performed through PGP signatures and OpenTimestamps to guarantee it stays unchanged. Comprehensive information and directions are available here.
