What's in it: graceful shutdown prep, sender-side amount control, xpay taking over from pay, xkeysend with modern routing, and BOLT12 payment proofs.

CLN 26.06rc1 is live. Graceful shutdowns, more control over payment amounts, and a smarter payment engine under the hood.

Please upgrade and send us your feedback or open an issue on GitHub. This is open source Lightning in action. ⚡

[Core Lightning ⚡️ @Core_LN]

Privacy isn't just about keys and addresses.

CLN v26.04 pads peer messages to a uniform length. An observer watching your node's traffic can no longer infer activity from message sizes.

Traffic analysis gets harder. That's by design.

NEW RELEASE: Blockstream’s Core-Lightning node implementation (@core_ln) v26.04 brings splicing to every node and adds padding to all wire messages, aiming to frustrate traffic analysis of messages on the network

[Core Lightning ⚡️ @Core_LN]

Open source Lightning improves because people show up and do the work. 421 commits. 110 days. 23 contributors, including six first-timers. The codebase is open. Eight bounties are up for grabs. Come build.

[Core Lightning ⚡️ @Core_LN]

Splicing lets you resize channels without closing them, cutting open/close overhead, freeing idle capital, and ending reliance on centralized liquidity providers. 26.04 also ships parallel pathfinding improvements, payer notes on xpay, and roughly 20% smaller binaries.
