v0.0.124

0.0.124 - Sep 3, 2024 - "Papercutting Feature Requests"

API Updates

• rust-bitcoin has been updated to 0.32. The new bitcoin-io crate is now
  used for all IO traits, irrespective of the features set on LDK crates.
  LDK crates no longer automatically force features on dependent crates where
  possible, allowing different std/no-std settings between LDK and
  rust-bitcoin crates (e.g. to disable std on LDK to ensure system time is
  not accessed while using bitcoin-io's std feature). (#3063, #3239, #3249).
• A new lightning_types crate was added which contains various top-level
  types. Using types from lightning::ln::features or
  Payment{Hash,Preimage,Secret} from lightning::ln or
  lightning::ln::types is now deprecated. The new crate is re-exported as
  lightning::types (#3234, #3253).
• lightning now depends on lightning-invoice, rather than the other way
  around. The lightning_invoice::payment module has moved to
  lightning::ln::bolt11_payment and lightning_invoice::utils to
  lightning::ln::invoice_utils (#3234).
• Event handlers may now return errors, causing most events to be replayed
  immediately without blocking the background processor. See documentation on
  individual Events for more information on replay (#2995).
• ChannelDetails::balance_msat is deprecated in favor of
  ChainMonitor::get_claimable_balances and the Balance, which now contains
  substantially more details and more accurately calculates a node-wide
  balance when Balance::claimable_amount_satoshis are summed (#3212, #3247).
• ConfirmationTarget has two new variants - a MaximumFeeEstimate which can
  help to avoid spurious force-closes by ensuring we always accept feerates up
  to this value from peers as sane and a UrgentOnChainSweep, replacing
  OnChainSweep and only being used when the on-chain sweep is urgent (#3268).
• All ChannelMonitors are no longer persisted after each block connection,
  instead spreading them out over a handful of blocks to reduce load spikes.
  Note that this will increase the incidence of ChannelMonitors that have
  different best blocks on startup, requiring some additional chain replay
  (but only on some ChannelMonitors) on startup for Listen users (#2966).
• A new format for Rapid Gossip Sync data is now supported which contains
  additional node metadata and is more extensible (#3098).
• ChannelManager::send_payment_with_route is now deprecated in favor of the
  much easier to use Channelmanager::send_payment. Those who wish to manually
  select the route such payments go over should do so by matching the
  payment_id passed to send_payment in Router::find_route_with_id (#3224)
• lightning-transaction-sync now takes most Confirms as a generic Deref.
  You may need an explicit as &(dyn Confirm) to update existing code (#3101).
• HTLCs will now be forwarded over any channel with a peer, rather than only
  the specific channel requested by the payment sender (#3127).
• Event::PaymentFailed is now used in place of Event::InvoiceRequestFailed,
  holding an Option for the payment hash, which will be None when no
  invoice has been received (#3192).
• ChannelManager now supports intercepting and manually paying
  Bolt12Invoices, see UserConfig::manually_handle_bolt12_invoices (#3078).
• logger::Records now contain a PaymentHash (#2930).
• ChainMonitor no longer uses an opaque MonitorUpdateId, opting to reuse
  the ChannelMonitorUpdate::update_id instead. Note that you no longer have
  to call ChainMonitor::channel_monitor_updated for
  ChannelMonitorUpdateStatus::InProgress updates to a monitor that were
  started without a ChannelMonitorUpdate (#2957).
• NodeAnnouncementInfo is now an enum holding either a gossip message or
  the important fields, reducing the memory usage of NetworkGraph (#3072).
• Onion message handlers now include a message context, which allows for
  blinded path authentication (#3085, #3202).
• ChannelManager now supports funding with only a txid and output index, see
  ChannelManager::unsafe_manual_funding_transaction_generated (#3024).
• BOLT 12 invoice requests now go out over, and accept responses over, multiple
  paths (#3087).
• OnionMessenger now supports intercepting and re-forwarding onion messages
  for peers that are offline at the time of receipt when constructed with
  new_with_offline_peer_interception (#2973).
• Onion message handling trait methods now generally take a Responder which
  can be used to create a ResponseInstruction to better control how responses
  are sent. The ResponseInstruction can also be converted to
  MessageSendInstructions which can be passed to OnionMessenger's
  send_onion_message to respond asynchronously (#2907, #2996, #3263).
• OnionMessenger::process_pending_events_async was added (#3060).
• Blinded paths used for BOLT 12 Offer/Refunds are now compact when they
  expire relatively soon, making them somewhat smaller (#3011, #3080).
• ChannelManager::force_close_* now take a err msg to send to peers (#2889).
• ChannelDetails::is_public has been renamed to is_announced and
  ChannelHandshakeConfig::announced_channel to announce_for_forwarding to
  address various misconceptions about the purpose of announcement (#3257).
• BlindedPaths are now split into BlindedMessagePaths and
  BlindedPaymentPaths and advance_path_by_one added to each (#3182).
• BlindedPaymentPath now includes the BlindedPayInfo (#3245).
• BOLT 12 Offer/Refund builders no longer require a description, instead
  allowing it to be set on the builder itself (#3018).
• The {Inbound,Outbound}HTLCState{,Details} and ChannelDetails structs have
  moved to the ln::channel_state module (#3089).
• Event::OpenChannelRequest now contains params and is_announced (#3019).
• Peers are no longer disconnected when we force-close a channel (#3088).
• BOLT12 Offer and Refund now implement Readable (#2965).
• RecipientOnionFields is now included in Event::PaymentClaimed (#3084).
• ClosureReason::HolderForceClosed::broadcasted_latest_txn was added (#3107).
• EcdsaChannelSigner no longer needs to be Writeable and the supertrait
  WriteableEcdsaChannelSigner has been removed (#3059).
• CustomMessageHandler::peer_{,dis}connected were added (#3105).
• lightning_invoice::Description::as_inner() was added (#3203).
• Splice-related wire messages have been updated to the latest spec (#3129).

Bug Fixes

• channel_update messages are no longer extracted from failed payments and
  applied to the network graph via Event::PaymentPathFailed, preventing a
  node along the path from identifying the sender of a payment (#3083).
• In order to prevent senders from identifying the recipient of a BOLT 12 offer
  that included a blinded path, cryptographic information from blinded paths
  are now included in the invoice request verification (#3085, #3139, #3242).
• Routes are now length-limited based on the actual onion contents rather than
  a fixed value. This ensures no routes are generated that are unpayable when
  sending HTLCs with custom TLVs, blinded paths, or metadata (#3026, #3156).
• Unannounced LDK nodes (or ones without a network graph) will now include
  unannounced peers as introduction points in blinded paths. This addresses
  issues where test networks were not usable for BOLT 12 due to failures to
  find paths over private channels to LDK nodes. It will also enable creating
  BOLT 12 offers for nodes with no local network graph (#3132).
• If a channel partner fails to update the feerate on a channel for some time
  and prevailing network feerates increase, LDK will now force-close
  automatically to avoid being unable to claim our funds on-chain. In order to
  reduce false-positives, it does so by comparing the channel's fee against the
  minimum ConfirmationTarget::MinAllowed{,Non}AnchorChannelRemoteFee we've
  seen over the past day (and do not force-close if we haven't been running for
  a full day, #3037).
• MonitorUpdatingPersister did not read ChannelMonitorUpdates when
  archiving a ChannelMonitor, causing the archived ChannelMonitor to be
  missing some updates. Those updates were not removed from the KVStore and
  monitors being archived should have no pending updates as they were persisted
  on each new block for some time before archiving (#3276).
• CoinSelections selected for commitment transactions which did not contain a
  change output no longer result in broadcasting a non-standard transaction nor
  in under-paying the target feerate (#3285). Note that such a transaction
  would fail to propagate and LDK would have continued to bump the fee until a
  different CoinSelection is used which did contain a change output.
• invoice_errors from BOLT 12 recipients now fail payments (#3085, #3192).
• Fixed a bug which may lead to a missing Event::ChannelClosed and missing
  Error messages for peers when a bogus funding transaction is provided for a
  batch channel open (#3029).
• Fixed an overflow in RawBolt11Invoice::amount_pico_btc() reachable via
  Bolt11Invoice::amount_milli_satoshis(), resulting in a debug panic or bogus
  value for invoices with invalid values (#3032).
• In incredibly rare circumstances, when using the beta asynchronous
  persistence, it is possible that the preimage for an MPP claim could fail to
  be persisted in the ChannelMonitor for one or more MPP parts, resulting in
  only some of the payment's value being claimed (#3120).
• A rare race was fixed which could lead to ChannelMonitorUpdates appearing
  after a full ChannelMonitor persistence th...

v0.0.123

v0.0.123 - May 08, 2024 - "BOLT12 Dust Sweeping"

API Updates

• To reduce risk of force-closures and improve HTLC reliability the default
  dust exposure limit has been increased to
  MaxDustHTLCExposure::FeeRateMultiplier(10_000). Users with existing
  channels might want to consider using
  ChannelManager::update_channel_config to apply the new default (#3045).
• ChainMonitor::archive_fully_resolved_channel_monitors is now provided to
  remove from memory ChannelMonitors that have been fully resolved on-chain
  and are now not needed. It uses the new Persist::archive_persisted_channel
  to inform the storage layer that such a monitor should be archived (#2964).
• An OutputSweeper is now provided which will automatically sweep
  SpendableOutputDescriptors, retrying until the sweep confirms (#2825).
• After initiating an outbound channel, a peer disconnection no longer results
  in immediate channel closure. Rather, if the peer is reconnected before the
  channel times out LDK will automatically retry opening it (#2725).
• PaymentPurpose now has separate variants for BOLT12 payments, which
  include fields from the invoice_request as well as the OfferId (#2970).
• ChannelDetails now includes a list of in-flight HTLCs (#2442).
• Event::PaymentForwarded now includes skimmed_fee_msat (#2858).
• The hashbrown dependency has been upgraded and the use of ahash as the
  no-std hash table hash function has been removed. As a consequence, LDK's
  Hash{Map,Set}s no longer feature several constructors when LDK is built
  with no-std; see the util::hash_tables module instead. On platforms that
  getrandom supports, setting the possiblyrandom/getrandom feature flag
  will ensure hash tables are resistant to HashDoS attacks, though the
  possiblyrandom crate should detect most common platforms (#2810, #2891).
• ChannelMonitor-originated requests to the ChannelSigner can now fail and
  be retried using ChannelMonitor::signer_unblocked (#2816).
• SpendableOutputDescriptor::to_psbt_input now includes the witness_script
  where available as well as new proprietary data which can be used to
  re-derive some spending keys from the base key (#2761, #3004).
• OutPoint::to_channel_id has been removed in favor of
  ChannelId::v1_from_funding_outpoint in preparation for v2 channels with a
  different ChannelId derivation scheme (#2797).
• PeerManager::get_peer_node_ids has been replaced with list_peers and
  peer_by_node_id, which provide more details (#2905).
• Bolt11Invoice::get_payee_pub_key is now provided (#2909).
• Default[Message]Router now take an entropy_source argument (#2847).
• ClosureReason::HTLCsTimedOut has been separated out from
  ClosureReason::HolderForceClosed as it is the most common case (#2887).
• ClosureReason::CooperativeClosure is now split into
  {Counterparty,Locally}Initiated variants (#2863).
• Event::ChannelPending::channel_type is now provided (#2872).
• PaymentForwarded::{prev,next}_user_channel_id are now provided (#2924).
• Channel init messages have been refactored towards V2 channels (#2871).
• BumpTransactionEvent now contains the channel and counterparty (#2873).
• util::scid_utils is now public, with some trivial utilities to examine
  short channel ids (#2694).
• DirectedChannelInfo::{source,target} are now public (#2870).
• Bounds in lightning-background-processor were simplified by using
  AChannelManager (#2963).
• The Persist impl for KVStore no longer requires Sized, allowing for
  the use of dyn KVStore as Persist (#2883, #2976).
• From<PaymentPreimage> is now implemented for PaymentHash (#2918).
• NodeId::from_slice is now provided (#2942).
• ChannelManager deserialization may now fail with DangerousValue when
  LDK's persistence API was violated (#2974).

Bug Fixes

• Excess fees on counterparty commitment transactions are now included in the
  dust exposure calculation. This lines behavior up with some cases where
  transaction fees can be burnt, making them effectively dust exposure (#3045).
• Futures used as an std::...::Future could grow in size unbounded if it
  was never woken. For those not using async persistence and using the async
  lightning-background-processor, this could cause a memory leak in the
  ChainMonitor (#2894).
• Inbound channel requests that fail in
  ChannelManager::accept_inbound_channel would previously have stalled from
  the peer's perspective as no error message was sent (#2953).
• Blinded path construction has been tuned to select paths more likely to
  succeed, improving BOLT12 payment reliability (#2911, #2912).
• After a reorg, lightning-transaction-sync could have failed to follow a
  transaction that LDK needed information about (#2946).
• RecipientOnionFields' custom_tlvs are now propagated to recipients when
  paying with blinded paths (#2975).
• Event::ChannelClosed is now properly generated and peers are properly
  notified for all channels that as a part of a batch channel open fail to be
  funded (#3029).
• In cases where user event processing is substantially delayed such that we
  complete multiple round-trips with our peers before a PaymentSent event is
  handled and then restart without persisting the ChannelManager after having
  persisted a ChannelMonitor[Update], on startup we may have Errd trying to
  deserialize the ChannelManager (#3021).
• If a peer has relatively high latency, PeerManager may have failed to
  establish a connection (#2993).
• ChannelUpdate messages broadcasted for our own channel closures are now
  slightly more robust (#2731).
• Deserializing malformed BOLT11 invoices may have resulted in an integer
  overflow panic in debug builds (#3032).
• In exceedingly rare cases (no cases of this are known), LDK may have created
  an invalid serialization for a ChannelManager (#2998).
• Message processing latency handling BOLT12 payments has been reduced (#2881).
• Latency in processing Event::SpendableOutputs may be reduced (#3033).

Node Compatibility

• LDK's blinded paths were inconsistent with other implementations in several
  ways, which have been addressed (#2856, #2936, #2945).
• LDK's messaging blinded paths now support the latest features which some
  nodes may begin relying on soon (#2961).
• LDK's BOLT12 structs have been updated to support some last-minute changes to
  the spec (#3017, #3018).
• CLN v24.02 requires the gossip_queries feature for all peers, however LDK
  by default does not set it for those not using a P2PGossipSync (e.g. those
  using RGS). This change was reverted in CLN v24.02.2 however for now LDK
  always sets the gossip_queries feature. This change is expected to be
  reverted in a future LDK release (#2959).

Security

0.0.123 fixes a denial-of-service vulnerability which we believe to be reachable
from untrusted input when parsing invalid BOLT11 invoices containing non-ASCII
characters.

• BOLT11 invoices with non-ASCII characters in the human-readable-part may
  cause an out-of-bounds read attempt leading to a panic (#3054). Note that all
  BOLT11 invoices containing non-ASCII characters are invalid.

v0.0.122

0.0.122 - Apr 09, 2024 - "That Which Is Untested Is Broken"

Bug Fixes

• Route objects did not successfully round-trip through de/serialization
  since LDK 0.0.117, which has now been fixed (#2897).
• Correct deserialization of unknown future enum variants. This ensures
  downgrades from future versions of LDK do not result in read failures or
  corrupt reads in cases where enums are written (#2969).
• When hitting lnd bug 6039, our workaround previously resulted in
  ChannelManager persistences on every round-trip with our peer. These
  useless persistences are now skipped (#2937).

v0.0.121

0.0.121 - Jan 22, 2024 - "Unwraps are Bad"

Bug Fixes

• Fix a deadlock when calling batch_funding_transaction_generated with
  invalid input (#2841).

Security

0.0.121 fixes a denial-of-service vulnerability which is reachable from
untrusted input from peers in rare cases if we have a public channel or in
common cases if P2PGossipSync is used.

• A peer that failed to complete its handshake would cause a reachable
  unwrap in LDK since 0.0.119 when LDK attempts to broadcast gossip to all
  peers (#2842).

v0.0.120

v0.0.120 - Jan 17, 2024 - "Unblinded Fuzzers"

API Updates

• The PeerManager bound on UtxoLookup was removed entirely. This enables
  use of UtxoLookup in cases broken in 0.0.119 by #2773 (#2822).
• LDK now exposes and fully implements the route blinding feature (#2812).
• The lightning-transaction-sync crate no longer relies on system time
  without the time feature (#2799, #2817).
• lightning::onion_message's module layout has changed (#2821).
• Event::ChannelClosed now includes the channel_funding_txo (#2800).
• CandidateRouteHop variants were destructured into individual structs,
  hiding some fields which were not generally consumable (#2802).

Bug Fixes

• Fixed a rare issue where lightning-net-tokio may not fully flush its send
  buffer, leading to connection hangs (#2832).
• Fixed a panic which may occur when connecting to a peer if we opened a second
  channel with that peer while they were disconnected (#2808).
• Retries for a payment which previously failed in a blinded path will now
  always use an alternative blinded path (#2818).
• Feature's Eq and Hash implementation now ignore dummy bytes (#2808).
• Some missing DiscardFunding or ChannelClosed events are now generated in
  rare funding-related failures (#2809).
• Fixed a privacy issue in blinded path generation where the real
  cltv_expiry_delta would be exposed to senders (#2831).

Security

0.0.120 fixes a denial-of-service vulnerability which is reachable from
untrusted input from peers if the UserConfig::manually_accept_inbound_channels
option is enabled.

• A peer that sent an open_channel message with the channel_type field
  unfilled would trigger a reachable unwrap since LDK 0.0.117 (#2808).
• In protocols where a funding output is shared with our counterparty before
  it is given to LDK, a malicious peer could have caused a reachable panic
  by reusing the same funding info in (#2809).

v0.0.119

v0.0.119 - Dec 15, 2023 - "Spring Cleaning for Christmas"

API Updates

• The LDK crate ecosystem MSRV has been increased to 1.63 (#2681).
• The bitcoin dependency has been updated to version 0.30 (#2740).
• lightning-invoice::payment::* have been replaced with parameter generation
  via payment_parameters_from[_zero_amount]_invoice (#2727).
• {CoinSelection,Wallet}Source::sign_tx are now sign_psbt, providing more
  information, incl spent outputs, about the transaction being signed (#2775).
• Logger Records now include channel_id and peer_id fields. These are
  opportunistically filled in when a log record is specific to a given channel
  and/or peer, and may occasionally be spuriously empty (#2314).
• When handling send or reply onion messages (e.g. for BOLT12 payments), a new
  Event::ConnectionNeeded may be raised, indicating a direct connection
  should be made to a payee or an introduction point. This event is expected to
  be removed once onion message forwarding is widespread in the network (#2723)
• Scoring data decay now happens via ScoreUpDate::time_passed, called from
  lightning-background-processor. process_events_async now takes a new
  time-fetch function, and ScoreUpDate methods now take the current time as a
  Duration argument. This avoids fetching time during pathfinding (#2656).
• Receiving payments to multi-hop blinded paths is now supported (#2688).
• MessageRouter and Router now feature methods to generate blinded paths to
  the local node for incoming messages and payments. Router now extends
  MessageRouter, and both are used in ChannelManager when processing or
  creating BOLT12 structures to generate multi-hop blinded paths (#1781).
• lightning-transaction-sync now supports Electrum-based sync (#2685).
• Confirm::get_relevant_txids now returns the height at which a transaction
  was confirmed. This can be used to assist in reorg detection (#2685).
• ConfirmationTarget::MaxAllowedNonAnchorChannelRemoteFee has been removed.
  Non-anchor channel feerates are bounded indirectly through
  ChannelConfig::max_dust_htlc_exposure (#2696).
• lightning-invoice Descriptions now rely on UntrustedString for
  sanitization (#2730).
• ScoreLookUp::channel_penalty_msat now uses CandidateRouteHop (#2551).
• The EcdsaChannelSigner trait was moved to lightning::sign::ecdsa (#2512).
• SignerProvider::get_destination_script now takes channel_keys_id (#2744)
• SpendableOutputDescriptor::StaticOutput now has channel_keys_id (#2749).
• EcdsaChannelSigner::sign_counterparty_commitment now takes HTLC preimages
  for both inbound and outbound HTLCs (#2753).
• ClaimedHTLC now includes a counterparty_skimmed_fee_msat field (#2715).
• peel_payment_onion was added to decode an encrypted onion for a payment
  without receiving an HTLC. This allows for stateless verification of if a
  theoretical payment would be accepted prior to receipt (#2700).
• create_payment_onion was added to construct an encrypted onion for a
  payment path without sending an HTLC immediately (#2677).
• Various keys used in channels are now wrapped to provide type-safety for
  specific usages of the keys (#2675).
• TaggedHash now includes the raw tag and merkle_root (#2687).
• Offer::is_expired_no_std was added (#2689).
• PaymentPurpose::preimage() was added (#2768).
• temporary_channel_id can now be specified in create_channel (#2699).
• Wire definitions for splicing messages were added (#2544).
• Various lightning-invoice structs now impl Display, now have pub fields,
  or impl From (#2730).
• The Hash trait is now implemented for more structs, incl P2P msgs (#2716).

Performance Improvements

• Memory allocations (though not memory usage) have been substantially reduced,
  meaning less overhead and hopefully less memory fragmentation (#2708, #2779).

Bug Fixes

• Since 0.0.117, calling close_channel* on a channel which has not yet been
  funded would previously result in an infinite loop and hang (#2760).
• Since 0.0.116, sending payments requiring data in the onion for the recipient
  which was too large for the onion may have caused corruption which resulted
  in payment failure (#2752).
• Cooperative channel closure on channels with remaining output HTLCs may have
  spuriously force-closed (#2529).
• In LDK versions 0.0.116 through 0.0.118, in rare cases where skimmed fees are
  present on shutdown the ChannelManager may fail to deserialize (#2735).
• ChannelConfig::max_dust_exposure values which, converted to absolute fees,
  exceeded 2^63 - 1 would result in an overflow and could lead to spurious
  payment failures or channel closures (#2722).
• In cases where LDK is operating with provably-stale state, it panics to
  avoid funds loss. This may not have happened in cases where LDK was behind
  only exactly one state, leading instead to a revoked broadcast and funds
  loss (#2721).
• Fixed a bug where decoding Txids from Bitcoin Core JSON-RPC responses using
  lightning-block-sync would not properly byte-swap the hash. Note that LDK
  does not use this API internally (#2796).

Backwards Compatibility

• ChannelManagers written with LDK 0.0.119 are no longer readable by versions
  of LDK prior to 0.0.113. Users wishing to downgrade to LDK 0.0.112 or before
  can read an 0.0.119-serialized ChannelManager with a version of LDK from
  0.0.113 to 0.0.118, re-serialize it, and then downgrade (#2708).
• Nodes that upgrade to 0.0.119 and subsequently downgrade after receiving a
  payment to a blinded path may leak recipient information if one or more of
  those HTLCs later fails (#2688).
• Similarly, forwarding a blinded HTLC and subsequently downgrading to an LDK
  version prior to 0.0.119 may result in leaking the path information to the
  payment sender (#2540).

v0.0.118

0.0.118 - Oct 23, 2023 - "Just the Twelve Sinks"

API Updates

• BOLT12 sending and receiving is now supported as an alpha feature. You may
  run into unexpected issues and will need to have a direct connection with
  the offer's blinded path introduction points as messages are not yet routed.
  We are seeking feedback from early testers (#2578, #2039).
• ConfirmationTarget has been rewritten to provide information about the
  specific use LDK needs the feerate estimate for, rather than the generic
  low-, medium-, and high-priority estimates. This allows LDK users to more
  accurately target their feerate estimates (#2660). For those wishing to
  retain their existing behavior, see the table below for conversion.
• ChainHash is now used in place of BlockHash where it represents the
  genesis block (#2662).
• lightning-invoice payment utilities now take a Deref to
  AChannelManager (#2652).
• peel_onion is provided to statelessly decode an OnionMessage (#2599).
• ToSocketAddrs + Display are now impl'd for SocketAddress (#2636, #2670)
• Display is now implemented for OutPoint (#2649).
• Features::from_be_bytes is now provided (#2640).

For those moving to the new ConfirmationTarget, the new variants in terms of
the old mempool/low/medium/high priorities are as follows:

• OnChainSweep = HighPriority
• MaxAllowedNonAnchorChannelRemoteFee = max(25 * 250, HighPriority * 10)
• MinAllowedAnchorChannelRemoteFee = MempoolMinimum
• MinAllowedNonAnchorChannelRemoteFee = Background - 250
• AnchorChannelFee = Background
• NonAnchorChannelFee = Normal
• ChannelCloseMinimum = Background

Bug Fixes

• Calling ChannelManager::close_channel[_with_feerate_and_script] on a
  channel which did not exist would immediately hang holding several key
  ChannelManager-internal locks (#2657).
• Channel information updates received from a failing HTLC are no longer
  applied to our NetworkGraph. This prevents a node which we attempted to
  route a payment through from being able to learn the sender of the payment.
  In some rare cases, this may result in marginally reduced payment success
  rates (#2666).
• Anchor outputs are now properly considered when calculating the amount
  available to send in HTLCs. This can prevent force-closes in anchor channels
  when sending payments which overflow the available balance (#2674).
• A peer that sends an update_fulfill_htlc message for a forwarded HTLC,
  then reconnects prior to sending a commitment_signed (thus retransmitting
  their update_fulfill_htlc) may result in the channel stalling and being
  unable to make progress (#2661).
• In exceedingly rare circumstances, messages intended to be sent to a peer
  prior to reconnection can be sent after reconnection. This could result in
  undefined channel state and force-closes (#2663).

Backwards Compatibility

• Creating a blinded path to receive a payment then downgrading to LDK prior to
  0.0.117 may result in failure to receive the payment (#2413).
• Calling ChannelManager::pay_for_offer or
  ChannelManager::create_refund_builder may prevent downgrading to LDK prior
  to 0.0.118 until the payment times out and has been removed (#2039).

Node Compatibility

• LDK now sends a bogus channel_reestablish message to peers when they ask to
  resume an unknown channel. This should cause LND nodes to force-close and
  broadcast the latest channel state to the chain. In order to trigger this
  when we wish to force-close a channel, LDK now disconnects immediately after
  sending a channel-closing error message. This should result in cooperative
  peers also working to confirm the latest commitment transaction when we wish
  to force-close (#2658).

Security

0.0.118 expands mitigations against transaction cycling attacks to non-anchor
channels, though note that no mitigations which exist today are considered robust
to prevent the class of attacks.

• In order to mitigate against transaction cycling attacks, non-anchor HTLC
  transactions are now properly re-signed before broadcasting (#2667).

v0.0.117

0.0.117 - Oct 3, 2023 - "Everything but the Twelve Sinks"

API Updates

• ProbabilisticScorer's internal models have been substantially improved,
  including better decaying (#1789), a more granular historical channel
  liquidity tracker (#2176) and a now-default option to make our estimate for a
  channel's current liquidity nonlinear in the channel's capacity (#2547). In
  total, these changes should result in improved payment success rates at the
  cost of slightly worse routefinding performance.
• Support for custom TLVs for recipients of HTLCs has been added (#2308).
• Support for generating transactions for third-party watchtowers has been
  added to ChannelMonitor/Updates (#2337).
• KVStorePersister has been replaced with a more generic and featureful
  KVStore interface (#2472).
• A new MonitorUpdatingPersister is provided which wraps a KVStore and
  implements Persist by writing differential updates rather than full
  ChannelMonitors (#2359).
• Batch funding of outbound channels is now supported using the new
  ChannelManager::batch_funding_transaction_generated method (#2486).
• ChannelManager::send_preflight_probes has been added to probe a payment's
  potential paths while a user is providing approval for a payment (#2534).
• Fully asynchronous ChannelMonitor updating is available as an alpha
  preview. There remain a few known but incredibly rare race conditions which
  may lead to loss of funds (#2112, #2169, #2562).
• ChannelMonitorUpdateStatus::PermanentFailure has been removed in favor of a
  new ChannelMonitorUpdateStatus::UnrecoverableError. The new variant panics
  on use, rather than force-closing a channel in an unsafe manner, which the
  previous variant did (#2562). Rather than panicking with the new variant,
  users may wish to use the new asynchronous ChannelMonitor updating using
  ChannelMonitorUpdateStatus::InProgress.
• RouteParameters::max_total_routing_fee_msat was added to limit the fees
  paid when routing, defaulting to 1% + 50sats when using the new
  from_payment_params_and_value constructor (#2417, #2603, #2604).
• Implementations of UtxoSource are now provided in lightning-block-sync.
  Those running with a full node should use this to validate gossip (#2248).
• LockableScore now supports read locking for parallel routefinding (#2197).
• ChannelMonitor::get_spendable_outputs was added to allow for re-generation
  of SpendableOutputDescriptors for a channel after they were provided via
  Event::SpendableOutputs (#2609, #2624).
• [u8; 32] has been replaced with a ChannelId newtype for chan ids (#2485).
• NetAddress was renamed SocketAddress (#2549) and FromStr impl'd (#2134)
• For no-std users, parse_onion_address was added which creates a
  NetAddress from a "...onion" string and port (#2134, #2633).
• HTLC information is now provided in Event::PaymentClaimed::htlcs (#2478).
• The success probability used in historical penalties when scoring is now
  available via historical_estimated_payment_success_probability (#2466).
• RecentPaymentDetails::*::payment_id has been added (#2567).
• Route now contains a RouteParameters rather than a PaymentParameters,
  tracking the original arguments passed to routefinding (#2555).
• Balance::*::claimable_amount_satoshis was renamed amount_satoshis (#2460)
• *Features::set_*_feature_bit have been added for non-custom flags (#2522).
• channel_id was added to SpendableOutputs events (#2511).
• counterparty_node_id and channel_capacity_sats were added to
  ChannelClosed events (#2387).
• ChannelMonitor now implements Clone for Cloneable signers (#2448).
• create_onion_message was added to build an onion message (#2583, #2595).
• HTLCDescriptor now implements Writeable/Readable (#2571).
• SpendableOutputDescriptor now implements Hash (#2602).
• MonitorUpdateId now implements Debug (#2594).
• Payment{Hash,Id,Preimage} now implement Display (#2492).
• NodeSigner::sign_bolt12_invoice{,request} were added for future use (#2432)

Backwards Compatibility

• Users migrating to the new KVStore can use a concatentation of
  [{primary_namespace}/[{secondary_namespace}/]]{key} to build a key
  compatible with the previous KVStorePersister interface (#2472).
• Downgrading after receipt of a payment with custom HTLC TLVs may result in
  unintentionally accepting payments with TLVs you do not understand (#2308).
• Route objects (including pending payments) written by LDK versions prior
  to 0.0.117 won't be retryable after being deserialized by LDK 0.0.117 or
  above (#2555).
• Users of the MonitorUpdatingPersister can upgrade seamlessly from the
  default KVStore Persist implementation, however the stored
  ChannelMonitors are deliberately unreadable by the default Persist. This
  ensures the correct downgrade procedure is followed, which is: (#2359)
  • First, make a backup copy of all channel state,
  • then ensure all ChannelMonitorUpdates stored are fully applied to the
    relevant ChannelMonitor,
  • finally, write each full ChannelMonitor using your new Persist impl.

Bug Fixes

• Anchor channels which were closed by a counterparty broadcasting its
  commitment transaction (i.e. force-closing) would previously not generate a
  SpendableOutputs event for our to_remote (i.e. non-HTLC-encumbered)
  balance. Those with such balances available should fetch the missing
  SpendableOutputDescriptors using the new
  ChannelMonitor::get_spendable_outputs method (#2605).
• Anchor channels may result in spurious or missing Balance entries for HTLC
  balances (#2610).
• ChannelManager::send_spontaneous_payment_with_retry spuriously did not
  provide the recipient with enough information to claim the payment, leading
  to all spontaneous payments failing (#2475).
  send_spontaneous_payment_with_route was unaffected.
• The keysend feature on node announcements was spuriously un-set in 0.0.112
  and has been re-enabled (#2465).
• Fixed several races which could lead to deadlock when force-closing a channel
  (#2597). These races have not been seen in production.
• The ChannelManager is persisted substantially less when it has not changed,
  leading to substantially less I/O traffic for it (#2521, #2617).
• Passing new block data to ChainMonitor no longer results in all other
  monitor operations being blocked until it completes (#2528).
• When retrying payments, any excess amount sent to the recipient in order to
  meet an htlc_minimum constraint on the path is now no longer included in
  the amount we send in the retry (#2575).
• Several edge cases in route-finding around HTLC minimums were fixed which
  could have caused invalid routes or panics when built with debug assertions
  (#2570, #2575).
• Several edge cases in route-finding around HTLC minimums and route hints
  were fixed which would spuriously result in no route found (#2575, #2604).
• The user_channel_id passed to SignerProvider::generate_channel_keys_id
  for inbound channels is now correctly using the one passed to
  ChannelManager::accept_inbound_channel rather than a default value (#2428).
• Users of impl_writeable_tlv_based! no longer have use requirements (#2506).
• No longer force-close channels when counterparties send a channel_update
  with a bogus htlc_minimum_msat, which LND users can manually build (#2611).

Node Compatibility

• LDK now ignores error messages generated by LND in response to a
  shutdown message, avoiding force-closes due to LND bug 6039. This may
  lead to non-trivial bandwidth usage with LND peers exhibiting this bug
  during the cooperative shutdown process (#2507).

Security

0.0.117 fixes several loss-of-funds vulnerabilities in anchor output channels,
support for which was added in 0.0.116, in reorg handling, and when accepting
channel(s) from counterparties which are miners.

• When a counterparty broadcasts their latest commitment transaction for a
  channel with anchor outputs, we'd previously fail to build claiming
  transactions against any HTLC outputs in that transaction. This could lead
  to loss of funds if the counterparty is able to eventually claim the HTLC
  after a timeout (#2606).
• Anchor channels HTLC claims on-chain previously spent the entire value of any
  HTLCs as fee, which has now been fixed (#2587).
• If a channel is closed via an on-chain commitment transaction confirmation
  with a pending outbound HTLC in the commitment transaction, followed by a
  reorg which replaces the confirmed commitment transaction with a different
  (but non-revoked) commitment transaction, all before we learn the payment
  preimage for this HTLC, we may previously have not generated a proper
  claiming transaction for the HTLC's value (#2623).
• 0.0.117 now correctly handles channels for which our counterparty funded the
  channel with a coinbase transaction. As such transactions are not spendable
  until they've reached 100 confirmations, this could have resulted in
  accepting HTLC(s) which are not enforcible on-chain (#1924).

v0.0.116

0.0.116 - Jul 21, 2023 - "Anchoring the Roadmap"

API Updates

• Support for zero-HTLC-fee anchor output channels has been added and is now
  considered beta (#2367). Users who set
  ChannelHandshakeConfig::negotiate_anchors_zero_fee_htlc_tx should be
  prepared to handle the new Event::BumpTransaction, e.g. via the
  BumpTransactionEventHandler (#2089). Note that in order to do so you must
  ensure you always have a reserve of available unspent on-chain funds to use
  for CPFP. LDK currently makes no attempt to ensure this for you.
• Users who set ChannelHandshakeConfig::negotiate_anchors_zero_fee_htlc_tx
  and wish to accept inbound anchor-based channels must do so manually by
  setting UserConfig::manually_accept_inbound_channels (#2368).
• Support forwarding and accepting HTLCs with a reduced amount has been added,
  to support LSPs skimming a fee on the penultimate hop (#2319).
• BOLT11 and BOLT12 Invoice and related types have been renamed to include a
  BOLTNN prefix, ensuring uniqueness in lightning{,-invoice} crates (#2416).
• Scorers now have an associated type which represents a parameter passed
  when calculating penalties. This allows for the same Scorer to be used with
  different penalty calculation parameters (#2237).
• DefaultRouter is no longer restrained to a Mutex-wrapped Score,
  allowing it to be used in no-std builds (#2383).
• CustomMessageHandler::provided_{node,init}_features and various custom
  feature bit methods on *Features were added (#2204).
• Keysend/push payments using MPP are now supported when receiving if
  UserConfig::accept_mpp_keysend is set and when sending if specified in the
  PaymentParameters. Note that not all recipients support this (#2156).
• A new ConfirmationTarget::MempoolMinimum has been added (#2415).
• SpendableOutputDescriptor::to_psbt_input was added (#2286).
• ChannelManager::update_partial_channel_config was added (#2330).
• ChannelDetails::channel_shutdown_state was added (#2347).
• The shutdown script can now be provided at shutdown time via
  ChannelManager::close_channel_with_feerate_and_script (#2219).
• BroadcasterInterface now takes multiple transactions at once. While not
  available today, in the future single calls should be passed to a full node
  via a single batch/package transaction acceptance API (#2272).
• Balance::claimable_amount_satoshis was added (#2333).
• payment_{hash,preimage} have been added to some Balance variants (#2217).
• The lightning::chain::keysinterface is now lightning::sign (#2246).
• Routing to a blinded path has been implemented, though sending to such a
  route is not yet supported in ChannelManager (#2120).
• OffersMessageHandler was added for offers-related onion messages (#2294).
• The CustomMessageHandler parameter to PeerManager has moved to
  MessageHandler from PeerManager::new explicitly (#2249).
• Various P2P messages for dual funding channel establishment have been added,
  though handling for them is not yet in ChannelManager (#1794)
• Script-fetching methods in sign interfaces can now return errors, see docs
  for the implications of failing (#2213).
• The data_loss_protect option is now required when reading
  channel_reestablish messages, as many others have done (#2253).
• InFlightHtlcs::add_inflight_htlc has been added (#2042).
• The init message networks field is now written and checked (#2329).
• PeerManager generics have been simplified with the introduction of the
  APeerManager trait (#2249).
• ParitalOrd and Ord are now implemented for Invoice (#2279).
• ParitalEq and Debug are now implemented for InMemorySigner (#2328).
• ParitalEq and Eq are now implemented for PaymentError (#2316).
• NetworkGraph::update_channel_from_announcement_no_lookup was added (#2222).
• lightning::routing::gossip::verify_{channel,node}_announcement was added
  (#2307).

Backwards Compatibility

• PaymentParameters written with blinded path info using LDK 0.0.115 will not
  be readable in LDK 0.0.116, and vice versa.
• Forwarding less than Event::HTLCIntercepted::expected_outbound_amount_msat
  in ChannelManager::forward_intercepted_htlc may prevent the
  ChannelManager from being read by LDK prior to 0.0.116 (#2319)
• Setting ChannelConfig::accept_underpaying_htlcs may prevent the
  ChannelManager from being read by LDK prior to 0.0.116 and un-setting the
  parameter between restarts may lead to payment failures (#2319).
• ChannelManager::create_inbound_payment{,_for_hash}_legacy has been removed,
  removing the ability to create inbound payments which are claimable after
  downgrade to LDK 0.0.103 and prior. In the future handling such payments will
  also be removed (#2351).
• Some fields required by LDK 0.0.103 and earlier are no longer written, thus
  deserializing objects written by 0.0.116 with 0.0.103 may now fail (#2351).

Bug Fixes

• ChannelDetails::next_outbound_htlc_limit_msat was made substantially more
  accurate and a corresponding next_outbound_htlc_minimum_msat was added.
  This resolves issues where unpayable routes were generated due to
  overestimation of the amount which is payable over one of our channels as
  the first hop (#2312).
• A rare case where delays in processing Events generated by
  ChannelMonitors could lead to loss of those events in case of an untimely
  crash. This could lead to the loss of an Event::SpendableOutputs (#2369).
• Fixed a regression in 0.0.115 which caused PendingHTLCsForwardable events
  to be missed when processing phantom node receives. This caused such
  payments to be delayed until a further, unrelated HTLC came in (#2395).
• Peers which are unresponsive to channel messages for several timer ticks are
  now disconnected to allow for on-reconnection state machine reset. This
  works around some issues in LND prior to 16.3 which can cause channels to
  hang and eventually force-close (#2293).
• ChannelManager::new now requires the current time (either from a recent
  block header or the system clock), ensuring invoices created immediately
  after startup aren't already expired (#2372).
• Resolved an issue where reading a ProbabilisticScorer on some platforms
  (e.g. iOS) can lead to a panic (#2322).
• ChannelConfig::max_dust_htlc_exposure is now allowed to scale based on
  current fees, and the default has been updated to do so. This substantially
  reduces the chance of force-closure due to dust exposure. Note that existing
  channels will retain their current value and you may wish to update the
  value on your existing channels on upgrade (#2354).
• PeerManager::process_events no longer blocks in any case. This fixes a bug
  where reentrancy from PeerManager into user code which eventually calls
  process_events could lead to a deadlock (#2280).
• The persist timing of network graph and scoring in
  lightning-background-processor has been tweaked to provide more reliable
  persistence after updates to either (#2226).
• The number of route hints added to BOLT 11 invoices by the
  lightning-invoice::utils builders has been reduced to three to ensure
  invoices can be represented in scan-able QR codes (#2044).
• Fixed sending large onion messages, which would previously have resulted in
  an HMAC error on the second hop (#2277).
• Fixed a memory leak that may occur when a ChannelManager or
  ChannelMonitor is droped (#2233).
• A potential deadlock in calling NetworkGraph::eq was resolved (#2284).
• Fixed an overflow which prevented disconnecting peers in some minor cases
  with more than 31 peers (#2245).
• Gossip messages with an unknown chain hash are now ignored (#2230).
• Rapid Gossip Sync processing now fails on an unknown chain hash (#2324).
• RouteHintHop::htlc_maximum_msat is now enforced. Note that BOLT11 route
  hints do not have such a field so this code is generally unused (#2305).

Security

0.0.116 fixes a denial-of-service vulnerability which is reachable from
untrusted input from channel counterparties if a 0-conf channel exists with
that counterparty.

• A premature announcement_signatures message from a peer prior to a 0-conf
  channel's funding transaction receiving any confirmations would panic in any
  version since 0-conf channels were introduced (#2439).

v0.0.115

0.0.115 - Apr 24, 2023 - "Rebroadcast the Bugfixes"

API Updates

• The MSRV of the main LDK crates has been increased to 1.48 (#2107).
• Attempting to claim an un-expired payment on a channel which has closed no
  longer fails. The expiry time of payments is exposed via
  PaymentClaimable::claim_deadline (#2148).
• payment_metadata is now supported in Invoice deserialization, sending,
  and receiving (via a new RecipientOnionFields struct) (#2139, #2127).
• Event::PaymentFailed now exposes a failure reason (#2142).
• BOLT12 messages now support stateless generation and validation (#1989).
• The NetworkGraph is now pruned of stale data after RGS processing (#2161).
• Max inbound HTLCs in-flight can be changed in the handshake config (#2138).
• lightning-transaction-sync feature esplora-async-https was added (#2085).
• A ChannelPending event is now emitted after the initial handshake (#2098).
• PaymentForwarded::outbound_amount_forwarded_msat was added (#2136).
• ChannelManager::list_channels_by_counterparty was added (#2079).
• ChannelDetails::feerate_sat_per_1000_weight was added (#2094).
• Invoice::fallback_addresses was added to fetch bitcoin types (#2023).
• The offer/refund description is now exposed in Invoice{,Request} (#2206).

Backwards Compatibility

• Payments sent with the legacy *_with_route methods on LDK 0.0.115+ will no
  longer be retryable via the LDK 0.0.114- retry_payment method (#2139).
• Event::PaymentPathFailed::retry was removed and will always be None for
  payments initiated on 0.0.115 which fail on an earlier version (#2063).
• Routes and PaymentParameters with blinded path information will not be
  readable on prior versions of LDK. Such objects are not currently constructed
  by LDK, but may be when processing BOLT12 data in a coming release (#2146).
• Providing ChannelMonitorUpdates generated by LDK 0.0.115 to a
  ChannelMonitor on 0.0.114 or before may panic (#2059). Note that this is
  in general unsupported, and included here only for completeness.

Bug Fixes

• Fixed a case where process_events_async may poll a Future which has
  already completed (#2081).
• Fixed deserialization of u16 arrays. This bug may have previously corrupted
  the historical buckets in a ProbabilisticScorer. Users relying on the
  historical buckets may wish to wipe their scorer on upgrade to remove corrupt
  data rather than waiting on it to decay (#2191).
• The process_events_async task is now Send and can thus be polled on a
  multi-threaded runtime (#2199).
• Fixed a missing macro export causing
  impl_writeable_tlv_based_enum{,_upgradable} calls to not compile (#2091).
• Fixed compilation of lightning-invoice with both no-std and serde (#2187)
• Fix an issue where the background-processor would not wake when a
  ChannelMonitorUpdate completed asynchronously, causing delays (#2090).
• Fix an issue where process_events_async would exit immediately (#2145).
• Router calls from the ChannelManager now call find_route_with_id rather
  than find_route, as was intended and described in the API (#2092).
• Ensure process_events_async always exits if any sleep future returns true,
  not just if all sleep futures repeatedly return true (#2145).
• channel_update messages no longer set the disable bit unless the peer has
  been disconnected for some time. This should resolve cases where channels are
  disabled for extended periods of time (#2198).
• We no longer remove CLN nodes from the network graph for violating the BOLT
  spec in some cases after failing to pay through them (#2220).
• Fixed a debug assertion which may panic under heavy load (#2172).
• CounterpartyForceClosed::peer_msg is now wrapped in UntrustedString (#2114)
• Fixed a potential deadlock in funding_transaction_generated (#2158).

Security

• Transaction re-broadcasting is now substantially more aggressive, including a
  new regular rebroadcast feature called on a timer from the
  background-processor or from ChainMonitor::rebroadcast_pending_claims.
  This should substantially increase transaction confirmation reliability
  without relying on downstream TransactionBroadcaster implementations for
  rebroadcasting (#2203, #2205, #2208).
• Implemented the changes from BOLT PRs #1031, #1032, and #1040 which resolve a
  privacy vulnerability which allows an intermediate node on the path to
  discover the final destination for a payment (#2062).
