Version 25.05-patch.1+7 months ago

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.
