daywalker90/sling v4.0.0 on GitHub

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

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

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

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
