API Updates

  • ChannelManager::send_probe and Score::probe_{failed,successful} have
    been added to make probing more explicit, as well as new
    Event::Probe{Failed,Successful} events (#1567).
  • ProbabilisticScoringParameters::banned_nodes has been renamed
    manual_node_penalties and changed to take msat penalties (#1592).
  • Per-payment tracking of failed paths was added to enable configuration of
    ProbabilisticScoringParameters::considered_impossible_penalty_msat (#1600)
  • ProbabilisticScoringParameters::base_penalty_amount_multiplier_msat was
    added to allow a penalty that is only amount-dependent (#1617).
  • ProbabilisticScoringParameters::amount_penalty_multiplier_msat was renamed
    liquidity_penalty_amount_multiplier_msat (#1617).
  • A new Event::HTLCHandlingFailed has been added which provides visibility
    into failures to forward/claim accepted HTLCs (#1403).
  • Support has been added for DNS hostnames in the NetAddress type, see
    BOLT PR #911 (#1553).
  • GossipSync now has rapid, p2p, and none constructors (#1618).
  • lightning-net-tokio no longer requires types to be in Arcs (#1623).
  • The htlc_maximum_msat field is now required in ChannelUpdate gossip
    messages. In tests this rejects < 1% of channels (#1519).
  • ReadOnlyNetworkGraph::{channel,node} have been added to query for
    individual channel/node data, primarily for bindings users (#1543).
  • FeeEstimator implementations are now wrapped internally to ensure values
    below 253 sats/kW are never used (#1552).
  • Route selection no longer attempts to randomize path selection. This is
    unlikely to lead to a material change in the paths selected (#1610).

Bug Fixes

  • Fixed a panic when deserializing ChannelDetails objects (#1588).
  • When routing, channels are no longer fully saturated before MPP splits are
    generated, instead a configuration knob was added as
    PaymentParameters::max_channel_saturation_power_of_half (#1605).
  • Fixed a panic which occurred in ProbabilisticScorer when wallclock time
    goes backwards across a restart (#1603).

Serialization Compatibility

  • All new fields are ignored by prior versions of LDK. All new fields are not
    present when reading objects serialized by prior versions of LDK.
  • Channel information written in the NetworkGraph which is missing
    htlc_maximum_msat may be dropped on deserialization (#1519).
  • Similarly, node information written in the NetworkGraph which contains an
    invalid hostname may be dropped on deserialization (#1519).
