Greenlight 0.3.1 by the Blockstream Lightning team is here. This non-custodial service lets you hold your keys while we handle the node operations behind the scenes. Nodes now run Core Lightning v25.05 with the latest performance, protocol, and reliability improvements. image With this update, signer policies have been refined, especially around acceptable fee rates, an important step since CLN and the VLS Project use different data models. A zeroconf fix also ensures long-confirming channels will no longer be closed.
