+# 0.0.119 - 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 `Record`s 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` `Description`s 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 `Txid`s 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
+ * `ChannelManager`s 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).
