Removed

• Dropped support for CLN <= v24.02, upgrade your node!
• ⚠️ Make sure to comment out any removed options in your config
• sling-refresh-peers-interval: Lowering it from the default 1 doesn't help much and if you must set it higher your node is probably too slow anyways
• sling-refresh-gossmap-interval: Gossip reader is so fast now there is no good reason to keep it

Added

• sling-once: New command to rebalance a specific amount once
• sling-stats: Added human readable table view for when you provide a ShortChannelId, json flag can still be set
• Sling now also periodically reads constraint information from the xpay layer in CLN >= v24.11

Changed

• Optimized gossip file reader to be ~20x faster with similar memory usage. On my system it can read a fully synced gossip file in ~110ms and periodical checks for updates are now instant: ~0ms.
• Optimized route search to be ~2x faster, on my system down from ~25ms to ~13ms.
• Make use of the new trace level logging, some debug logs are now trace
• If possible show node alias in failure log message instead of id
• sling-reset-liquidity-interval: Default value increased to 360m again, if liquidity beliefs are forgotten too quickly it may result in an infinite loop of trying the very cheapest, never succeeding paths
• Slightly increased the minimum channel cost in pathfinding
• Use actual default options so they show up in CLN's listconfigs
• Refactor to show method usage in CLN's help
• switch from jemalloc to mimalloc for compatibility on systems using page sizes >4k

Fixed

• You can no longer add your own channels or your own node id to exceptions, for candidate control use candidatelist/outppm
• Jobstates are now sorted properly in the stats view

Release binaries info

• Release binaries were built using rust 1.88.0
• Linux release binaries require glibc>=2.31

Fixed

• no longer require scid aliases for private channels during route calculation aswell

Release binaries info

• Release binaries were built using rust 1.86.0
• Linux release binaries require glibc>=2.31

Changed

• no longer require scid aliases for private channels

Release binaries info

• Release binaries were built using rust 1.86.0
• Linux release binaries require glibc>=2.31

Added

• more debug logging for candidates selection

Changed

• only add private channels to graph if they have an alias, remove private channels without an alias
• lower log level to debug for repetitive graph refresh lines

Release binaries info

• Release binaries were built using rust 1.86.0
• Linux release binaries require glibc>=2.31

Changed

• check private channels for existing aliases when adding a job

Release binaries info

• Release binaries were built using rust 1.85.0
• Linux release binaries require glibc>=2.31

Fixed

• support modified cln clients with prefix in version strings

Release binaries info

• Release binaries were built using rust 1.85.0
• Linux release binaries require glibc>=2.31

Fixed

• no longer panic when private channels have missing aliases or bogus entries (still not possible to rebalance these channels without the correct data from cln)

Release binaries info

• Release binaries were built using rust 1.85.0
• Linux release binaries require glibc>=2.31

Added

• sling-inform-layers: CLN 24.11+ will inform these layers about sling's liquidity information gained by failed rebalances. Can be stated multiple times. Defaults to xpay which will help the xpay command.

Changed

• sling-reset-liquidity-interval defaults to 60m now and checks every 2m (previously: 360m/10m). This is to be in sync with the aging of xpay's layer

Fixed

• sling-refresh-peers-interval was not actually dynamic
• sling-refresh-aliasmap-interval was not actually dynamic
• sling-refresh-gossmap-interval was not actually dynamic
• sling-reset-liquidity-interval was not actually dynamic

Removed

• sling-utf8, it was not used

Release binaries info

• Release binaries were built using rust 1.83.0
• Linux release binaries require glibc>=2.31

Fixed

• rebalances between private channels would fail after the first if only private channels are candidates

Release binaries info

• Release binaries were built using rust 1.82.0
• Linux release binaries require glibc>=2.31

Added

• nix flake (thanks to @RCasatta)
• optional boolean argument for sling-stats to set output of the summary to json, e.g. sling-stats true

Changed

• updated dependencies
