0.0.112 - Oct 25, 2022 - "History Matters"

API Updates

• Result<(), ChannelMonitorUpdateErr> return values have been replaced with
  a ChannelMonitorUpdateStatus trinary enum. This better denotes that
  ChannelMonitorUpdateStatus::InProgress is not an error, but asynchronous
  persistence of a monitor update. Note that asynchronous persistence still
  has some edge cases and is not yet recommended for production (#1106).
• ChannelMonitor persistence failure no longer automatically broadcasts the
  latest commitment transaction. See the
  ChannelMonitorUpdateStatus::PermanentFailure docs for more info (#1106).
• *Features::known has been replaced with individual
  *MessageHandler::provided_*_features methods (#1707).
• OnionMessenger now takes a CustomOnionMessageHandler implementation,
  allowing you to send and receive custom onion messages (#1748).
• ProbabilisticScorer now tracks the historical distribution of liquidity
  estimates for channels. See new historical_* parameters in
  ProbabilisticScoringParameters for more details (#1625).
• lightning-block-sync's BlockSource trait now supports BIP 157/158
  filtering clients by returning only header data for some blocks (#1706).
• lightning-invoice's Router trait now accepts an InFlightHtlcs to
  ensure we do not over-use a remote channel's funds during routing (#1694).
  Note that this was previously backported to 0.0.111 for bindings users.
• NetworkGraph::remove_stale_channels has been renamed
  NetworkGraph::remove_stale_channels_and_tracking as NetworkGraph now
  refuses to re-add nodes and channels that were recently removed (#1649).
• The lightning-rapid-gossip-sync crate now supports no-std (#1708).
• The default ProbabilisticScoringParameters::liquidity_offset_half_life has
  been increased to six hours from one (#1754).
• All commitment transaction building logic for anchor outputs now assumes the
  no-HTLC-tx-fee variant (#1685).
• A number of missing Eq implementations were added (#1763).

Bug Fixes

• lightning-background-processor now builds without error with the futures
  feature (#1744).
• ChannelManager::get_persistable_update_future's returned Future has been
  corrected to not fail to be awoken in some cases (#1758).
• Asynchronously performing the initial ChannelMonitor persistence is now
  safe (#1678).
• Redundantly applying rapid gossip sync updates no longer Errs (#1764).
• Nodes which inform us via payment failures that they should no longer be
  used are now removed from the network graph. Some LND nodes spuriously
  generate this error and may remove themselves from our graph (#1649).
