ElementsProject/lightning v25.12.1

v25.12.1 Boltz's Seamless Upgrade Experience II

on GitHub

This is a recommended point release, particularly for those creating new nodes.

Fixed

• lightningd: we now correctly sign for non-taproot addresses given by nodes created by v25.12 or newer. ([#8831])
• lightning-hsmtool: handle mnemonic hsm_secret files (nodes created >= v25.12). ([#8831])
• plugins: pay can crash on errors returned from deep inside routehints. ([#8829])
• plugins: askrene can crash on a corner case in increase_flows. ([#8829])
• askrene: fix a plugin crash triggered during single path payments when a channel fees doesn't fit u32. ([#8832])
• JSON-RPC: malformed filters no longer crash lightningd. ([#8780])
• pay: maxdelay parameter now enforced for direct channel payments ([#8740])
• gossipd: we would occasionally not show a node announcement in listnodes(). ([#8769])
• lightningd: potential crash on startup if bitcoind isn't up-to-date. ([#8779])

Changed

• JSON-RPC: recover takes a 12-word mnemonic for nodes created by v25.12 or later. ([#8830])
• lightning-hsmtool: getsecret replaces getcodexsecret for modern nodes (gives mnemonic). ([#8830])

Deprecated

Note: You should always set allow-deprecated-apis=false to test for changes.

• lightning-hsmtool: getcodexsecret. Use getsecret. ([#8830])
