Note that mutexes are replaced with + no-ops for such builds (#1008, #1028). + * LDK now supports sending and receiving "keysend" payments. This includes + modifications to `lightning::util::events::Event::PaymentReceived` to + indicate the type of payment (#967). + * A new variant, `lightning::util::events::Event::PaymentForwarded` has been + added which indicates a forwarded payment has been successfully claimed and + we've received a forwarding fee (#1004). + * `lightning::chain::keysinterface::KeysInterface::get_shutdown_pubkey` has + been renamed to `get_shutdown_scriptpubkey`, returns a script, and is now + called on channel open only if + `lightning::util::config::ChannelConfig::commit_upfront_shutdown_pubkey` is + set (#1019). + * Closing-signed negotiation is now more configurable, with an explicit + `lightning::util::config::ChannelConfig::force_close_avoidance_max_fee_satoshis` + field allowing you to select the maximum amount you are willing to pay to + avoid a force-closure. Further, we are now less restrictive on the fee + placed on the closing transaction when we are not the party paying it. To + control the feerate paid on a channel at close-time, use + `ChannelManager::close_channel_with_target_feerate` instead of + `close_channel` (#1011). + * `lightning_background_processor::BackgroundProcessor` now stops the + background thread when dropped (#1007). It is marked `#[must_use]` so that + Rust users will receive a compile-time warning when it is immediately + dropped after construction (#1029). + * Total potential funds burn on force-close due to dust outputs is now limited + to `lightning::util::config::ChannelConfig::max_dust_htlc_exposure_msat` per + channel (#1009). + * The interval on which + `lightning::ln::peer_handler::PeerManager::timer_tick_occurred` should be + called has been reduced to once every five seconds (#1035) and + `lightning::ln::channelmanager::ChannelManager::timer_tick_occurred` should + now be called on startup in addition to once per minute (#985). + * The rust-bitcoin and bech32 dependencies have been updated to their + respective latest versions (0.27 and 0.8, #1012). + +## Bug Fixes + * Fix panic when reading invoices generated by some versions of c-lightning + (#1002 and #1003). + * Fix panic when attempting to validate a signed message of incorrect length + (#1010). + * Do not ignore the route hints in invoices when the invoice is over 250k + sats (#986). + * Fees are automatically updated on outbound channels to ensure commitment + transactions are always broadcastable (#985). + * Fixes a rare case where a `lightning::util::events::Event::SpendableOutputs` + event is not generated after a counterparty commitment transaction is + confirmed in a reorg when a conflicting local commitment transaction is + removed in the same reorg (#1022). + * Fixes a remotely-triggerable force-closure of an origin channel after an + HTLC was forwarded over a next-hop channel and the next-hop channel was + force-closed by our counterparty (#1025). + * Fixes a rare force-closure case when sending a payment as a channel fundee + when overdrawing our remaining balance. Instead the send will fail (#998). + * Fixes a rare force-closure case when a payment was claimed prior to a + peer disconnection or restart, and later failed (#977). ## Serialization Compatibility + * Pending inbound keysend payments which have neither been failed nor claimed + when serialized will result in a `ChannelManager` which is not readable on + pre-0.0.100 clients (#967). + * Because + `lightning::chain::keysinterface::KeysInterface::get_shutdown_scriptpubkey` + has been updated to return a script instead of only a `PublicKey`, + `ChannelManager`s constructed with custom `KeysInterface` implementations on + 0.0.100 and later versions will not be readable on previous versions. + `ChannelManager`s created with 0.0.99 and prior versions will remain readable + even after the a serialization roundtrip on 0.0.100, as long as no new + channels are opened. Further, users using a + `lightning::chain::keysinterface::KeysManager` as their `KeysInterface` will + have `ChannelManager`s which are readable on prior versions as well (#1019). + * `ChannelMonitorUpdate`s created by 0.0.100 and later for channels when + `lightning::util::config::ChannelConfig::commit_upfront_shutdown_pubkey` is + not set may not be readable by versions prior to 0.0.100 (#1019). * HTLCs which were in the process of being claimed on-chain when a pre-0.0.100 `ChannelMonitor` was serialized may generate `PaymentForwarded` events with spurious `fee_earned_msat` values. This only applies to payments which were - unresolved at the time of the upgrade. - * 0.0.100 clients with pending PaymentForwarded events at serialization-time - will generate serialized `ChannelManager` objects which 0.0.99 and earlier - clients cannot read. The likelihood of this can be reduced by ensuring you - process all pending events immediately before serialization (as is done by - the `lightning-background-processor` crate). + unresolved at the time of the upgrade (#1004). + * 0.0.100 clients with pending `Event::PaymentForwarded` events at + serialization-time will generate serialized `ChannelManager` objects which + 0.0.99 and earlier clients cannot read.
