+# 0.0.106 - 2022-04-03
+
+## API Updates
+ * Minimum supported rust version (MSRV) is now 1.41.1 (#1310).
+ * Lightning feature `option_scid_alias` is now supported and may be negotiated
+ when opening a channel with a peer. It can be configured via
+ `ChannelHandshakeConfig::negotiate_scid_privacy` and is off by default but
+ will be on by default in the future (#1351).
+ * `OpenChannelRequest` now has a `channel_type` field indicating the features
+ the channel will operate with and should be used to filter channels with
+ undesirable features (#1351). See the Serialization Compatibility section.
+ * `ChannelManager` supports sending and receiving short channel id aliases in
+ the `funding_locked` message. These are used when forwarding payments and
+ constructing invoice route hints for improved privacy. `ChannelDetails` has a
+ `inbound_scid_alias` field and a `get_inbound_payment_scid` method to support
+ the latter (#1311).
+ * `DefaultRouter` and `find_route` take an additional random seed to improve
+ privacy by adding a random CLTV expiry offset to each path's final hop. This
+ helps obscure the intended recipient from adversarial intermediate hops
+ (#1286). The seed is also used to randomize candidate paths during route
+ selection (#1359).
+ * The `lightning-block-sync` crate's `init::synchronize_listeners` method
+ interface has been relaxed to support multithreaded environments (#1349).
+ * `ChannelManager::create_inbound_payment_for_hash`'s documentation has been
+ corrected to remove the one-year restriction on `invoice_expiry_delta_secs`,
+ which is only applicable to the deprecated `create_inbound_payment_legacy`
+ and `create_inbound_payment_for_hash_legacy` methods (#1341).
+ * `Features` mutator methods now take `self` by reference instead of by value
+ (#1331).
+ * The CLTV of the last hop in a path is now included when comparing against
+ `RouteParameters::max_total_cltv_expiry_delta` (#1358).
+ * Invoice creation functions in `lightning-invoice` crate's `utils` module
+ include versions that accept a description hash instead of only a description
+ (#1361).
+ * `RoutingMessageHandler::sync_routing_table` has been renamed `peer_connected`
+ (#1368).
+ * `MessageSendEvent::SendGossipTimestampFilter` has been added to indicate that
+ a `gossip_timestamp_filter` should be sent (#1368).
+ * `PeerManager` takes an optional `NetAddress` in `new_outbound_connection` and
+ `new_inbound_connection`, which is used to report back the remote address to
+ the connecting peer in the `init` message (#1326).
+ * `ChannelManager::accept_inbound_channel` now takes a `user_channel_id`, which
+ is used in a similar manner as in outbound channels. (#1381).
+ * `BackgroundProcessor` now persists `NetworkGraph` on a timer and upon
+ shutdown as part of a new `Persister` trait, which also includes
+ `ChannelManager` persistence (#1376).
+ * `ProbabilisticScoringParameters` now has a `base_penalty_msat` option, which
+ default to 500 msats. It is applied at each hop to help avoid longer paths
+ (#1375).
+ * `ProbabilisticScoringParameters::liquidity_penalty_multiplier_msat`'s default
+ value is now 40,000 msats instead of 10,000 msats (#1375).
+ * The `lightning` crate has a `grind_signatures` feature used to produce
+ signatures with low r-values for more predictable transaction weight. This
+ feature is on by default (#1388).
+ * `ProbabilisticScoringParameters` now has a `amount_penalty_multiplier_msat`
+ option, which is used to further penalize large amounts (#1399).
+ * `PhantomRouteHints`, `FixedPenaltyScorer`, and `ScoringParameters` now
+ implement `Clone` (#1346).
+
+## Bug Fixes
+ * Fixed a compilation error in `ProbabilisticScorer` under `--feature=no-std`
+ (#1347).
+ * Invoice creation functions in `lightning-invoice` crate's `utils` module
+ filter invoice hints in order to limit the invoice size (#1325).
+ * Fixed a bug where a `funding_locked` message was delayed by a block if the
+ funding transaction was confirmed while offline, depending on the ordering
+ of `Confirm::transactions_confirmed` calls when brought back online (#1363).
+ * Fixed a bug in `NetGraphMsgHandler` where it didn't continue to receive
+ gossip messages from peers after initial connection (#1368, #1382).
+ * `ChannelManager::timer_tick_occurred` will now timeout a received multi-path
+ payment (MPP) after three ticks if not received in full instead of waiting
+ until near the HTLC timeout block(#1353).
+ * Fixed an issue with `find_route` causing it to be overly aggressive in using
+ MPP over channels to the same first hop (#1370).
+ * Reduced time spent processing `channel_update` messages by checking
+ signatures after checking if no newer messages have already been processed
+ (#1380).
+ * Fixed a few issues in `find_route` which caused preferring paths with a
+ higher cost (#1398).
+ * Fixed an issue in `ProbabilisticScorer` where a channel with not enough
+ liquidity could still be used when retrying a failed payment if it was on a
+ path with an overall lower cost (#1399).
+
+## Serialization Compatibility
+ * Channels open with `option_scid_alias` negotiated will be incompatible with
+ prior releases (#1351). This may occur in the following cases:
+ * Outbound channels when `ChannelHandshakeConfig::negotiate_scid_privacy` is
+ enabled.
+ * Inbound channels when automatically accepted from an `OpenChannel` message
+ with a `channel_type` that has `ChannelTypeFeatures::supports_scid_privacy`
+ return true. See `UserConfig::accept_inbound_channels`.
+ * Inbound channels when manually accepted from an `OpenChannelRequest` with a
+ `channel_type` that has `ChannelTypeFeatures::supports_scid_privacy` return
+ true. See `UserConfig::manually_accept_inbound_channels`.

+# 0.0.105 - 2022-02-28
+
+## API Updates
+ * `Phantom node` payments are now supported, allowing receipt of a payment on
+ any one of multiple nodes without any coordination across the nodes being
+ required. See the new `PhantomKeysManager`'s docs for more, as well as
+ requirements on `KeysInterface::get_inbound_payment_key_material` and
+ `lightning_invoice::utils::create_phantom_invoice` (#1199).
+ * In order to support phantom node payments, several `KeysInterface` methods
+ now accept a `Recipient` parameter to select between the local `node_id` and
+ a phantom-specific one.
+ * `ProbabilisticScorer`, a `Score` based on learning the current balances of
+ channels in the network, was added. It attempts to better capture payment
+ success probability than the existing `Scorer`, though may underperform on
+ nodes with low payment volume. We welcome feedback on performance (#1227).
+ * `Score::channel_penalty_msat` now always takes the channel value, instead of
+ an `Option` (#1227).
+ * `UserConfig::manually_accept_inbound_channels` was added which, when set,
+ generates a new `Event::OpenChannelRequest`, which allows manual acceptance
+ or rejection of incoming channels on a per-channel basis (#1281).
+ * `Payee` has been renamed to `PaymentParameters` (#1271).
+ * `PaymentParameters` now has a `max_total_cltv_expiry_delta` field. This
+ defaults to 1008 and limits the maximum amount of time an HTLC can be pending
+ before it will either fail or be claimed (#1234).
+ * The `lightning-invoice` crate now supports no-std environments. This required
+ numerous API changes around timestamp handling and std+no-std versions of
+ several methods that previously assumed knowledge of the time (#1223, #1230).
+ * `lightning-invoice` now supports parsing invoices with expiry times of more
+ than one year. This required changing the semantics of `ExpiryTime` (#1273).
+ * The `CounterpartyCommitmentSecrets` is now public, allowing external uses of
+ the `BOLT 3` secret storage scheme (#1299).
+ * Several `Sign` methods now receive HTLC preimages as proof of state
+ transition, see new documentation for more (#1251).
+ * `KeysInterface::sign_invoice` now provides the HRP and other invoice data
+ separately to make it simpler for external signers to parse (#1272).
+ * `Sign::sign_channel_announcement` now returns both the node's signature and
+ the per-channel signature. `InMemorySigner` now requires the node's secret
+ key in order to implement this (#1179).
+ * `ChannelManager` deserialization will now fail if the `KeysInterface` used
+ has a different `node_id` than the `ChannelManager` expects (#1250).
+ * A new `ErrorAction` variant was added to send `warning` messages (#1013).
+ * Several references to `chain::Listen` objects in `lightning-block-sync` no
+ longer require a mutable reference (#1304).
+
+## Bug Fixes
+ * Fixed a regression introduced in 0.0.104 where `ChannelManager`'s internal
+ locks could have an order violation leading to a deadlock (#1238).
+ * Fixed cases where slow code (including user I/O) could cause us to
+ disconnect peers with ping timeouts in `BackgroundProcessor` (#1269).
+ * Now persist the `ChannelManager` prior to `BackgroundProcessor` stopping,
+ preventing race conditions where channels are closed on startup even with a
+ clean shutdown. This requires that users stop network processing and
+ disconnect peers prior to `BackgroundProcessor` shutdown (#1253).
+ * Fields in `ChannelHandshakeLimits` provided via the `override_config` to
+ `create_channel` are now applied instead of the default config (#1292).
+ * Fixed the generation of documentation on docs.rs to include API surfaces
+ which are hidden behind feature flags (#1303).
+ * Added the `channel_type` field to `accept_channel` messages we send, which
+ may avoid some future compatibility issues with other nodes (#1314).
+ * Fixed a bug where, if a previous LDK run using `lightning-persister` crashed
+ while persisting updated data, we may have failed to initialize (#1332).
+ * Fixed a rare bug where having both pending inbound and outbound HTLCs on a
+ just-opened inbound channel could cause `ChannelDetails::balance_msat` to
+ underflow and be reported as large, or cause panics in debug mode (#1268).
+ * Moved more instances of verbose gossip logging from the `Trace` level to the
+ `Gossip` level (#1220).
+ * Delayed `announcement_signatures` until the channel has six confirmations,
+ slightly improving propagation of channel announcements (#1179).
+ * Several fixes in script and transaction weight calculations when anchor
+ outputs are enabled (#1229).
+
+## Serialization Compatibility
+ * Using `ChannelManager` data written by versions prior to 0.0.105 will result
+ in preimages for HTLCs that were pending at startup to be missing in calls
+ to `KeysInterface` methods (#1251).
+ * Any phantom invoice payments received on a node that is not upgraded to
+ 0.0.105 will fail with an "unknown channel" error. Further, downgrading to
+ 0.0.104 or before and then upgrading again will invalidate existing phantom
+ SCIDs which may be included in invoices (#1199).
+
+## Security
+0.0.105 fixes two denial-of-service vulnerabilities which may be reachable from
+untrusted input in certain application designs.
+
+ * Route calculation spuriously panics when a routing decision is made for a
+ path where the second-to-last hop is a private channel, included due to a
+ multi-hop route hint in an invoice.
+ * `ChannelMonitor::get_claimable_balances` spuriously panics in some scenarios
+ when the LDK application's local commitment transaction is confirmed while
+ HTLCs are still pending resolution.
