Core Lightning

This updates cln-application to v25.07.3, lightningd to v25.09.3, and replaces the legacy c-lightning-rest service with the built-in REST interface of lightningd.

CLN Application v25.07.3:

• Proactive mitigation against a widespread npm ecosystem threat involving malicious code in popular packages.
• Updated and streamlined environment variables for improved configuration and usability
• Added support for running Commando over secure WebSocket (eg. wss-proxy) connections
• Removed version and commit suffix from node aliases for a cleaner display
• Updated BKPR date format from YYYY-MM-DD to UI standard DD MMM, YYYY
• Added infinite scroll support for BTC Transactions, CLN Offers, and CLN Transactions

CLN v25.09.3:

• Bookkeeper has been migrated into core lightning, allowing visibility into payments, fees and channel activities.
• xpay can now directly pay BIP353 addresses (like ₿cln@blockstream.com) and simple offers without extra steps.
• Better feedback when channel creation fails due to capacity limits.
• Now limiting the number of parts a payment can be split on xpay and askrene
• Reckless now supports the modern uv package manager for Python plugins.
• Improvements to the rate of feasible solutions found in the main loop of the solver on askrene
• Splicing improvements allow for better compatibility with Eclair and continuous routing during channel modifications.
• Improve security by ensuring all peers must support channel type.
• Payment secrets now mandatory in BOLT11 invoices for better payment protection.

This update adds support for Backups in umbrelOS 1.5.

Previous release notes for v25.05:

This release of Core Lightning includes many improvements, bug fixes, and new features.

CLN Application v0.0.7:

• Adding long awaited Bookkeeper graphs for account events, sats flow and volume
• New SQL Terminal to run SQL queries directly from the UI
• Connect wallet modal shows clnrest and cln-grpc information

CLN Rest v0.10.7:

• added support for generating p2tr addresses

CLN v25.05:

• Reduced latency of commit and revoke messages.
• Reckless can update existing reckless-installed plugins via reckless update.
• Fixed routing of AskRene via high capacity channels.
• More accurate anchor fees.
• Channel backup turns our peers into watchtowers by now allowing your node to generate penalty transactions!
• blacklisted runes can now be restored via relist.
• xpay has many, many bugfixes, and is now almost seamlessly compatible when xpay-handle-pay is used.
• lightning-cli has neater help output, and doesn't crash occasionally on xpay notifications.
• setconfig does more safety checks and uses a separate "config.setconfig" file for runtime changes: you can also now set transient=true if you don't want the config files changed.
• Fixed a bug where we would fail to collect our own funds if we force closed a channel we had leased with --experimental-dual-fund.

This update makes the gRPC interface in Core Lightning accessible for companion apps you install.

For example, as a result of this change, the newest Ride The Lightning release integrates Boltz as a service, allowing you to seamlessly swap in and out of the Lightning Network.

This updates cln-application to v0.0.6, and lightningd to v24.11.1. cln-application v0.0.6:

• Bug fix: Change uppercase invoices and offers to lowercase.

• Enhancement: Create and Display Invoice Rune on Connect Wallet.

• Deprecation: Resolve commando-rune deprecation and use createrune instead.

lightningd v24.11.1:

• xpay is a new, experimental plugin for payments. It's rewritten from the ground up, on top of another plugin called askrene, which provides advanced routing advice for payments. The two play together: xpay tells askrene about the results of payment attempts, so it learns over time. The hard work was done by @Lagrang3 who wrote and refined the minimum-cost-flow solver which is the heart of askrene.

• Paying and receiving offers (bolt12 send and receive) are enabled by default! This reflects it finally being included in the BOLT specs in September, to applause from all the different Lightning implementers.

• listpays now takes start and limit parameters to speed it up if you only want recent payments.

• CLN is smarter about remembering where the node successfully connected out to a peer, and will always try that again.

• The autoclean plugin would make nodes freeze for 30 seconds at a time when had a lot of work to do: it is now kinder and gentler.

• Faster gossip which is helpful for everyone stay up-to-date with what is happening in the network.

• Connectd will connect faster on startup, maintaining up to 10 outgoing connection attempts in parallel.

• Some nasty bugs fixed, including one where extended downtime could mean we might never fully resolve unilateral closes (just missing returning the funds to our wallet).

• Stability fixes to gossip and anchor channel spends.

• Pruned node operation is better supported by bcli with more robust block fetching.
• Pay can now pay part of an invoice with the partial_msat parameter. Get someone else to pay the remainder.
• Check can now be used to validate setconfig settings and values. It can also check for approval by the hsmd of keysend payments.
• Offers will now make an outgoing connection if necessary to reply to an invoice request.
