This patch release fixes a panic that could have been hit when syncing to a TLS-enabled Electrum server, as well as some minor issues when shutting down the node.
- If not set by the user, we now install a default
CryptoProviderfor therustlsTLS library. This fixes an issue that would have the node panic whenever they first try to access an Electrum server behind anssl://address. (#600) - We improved robustness of the shutdown procedure. In particular, we now wait for more background tasks to finish processing before shutting down LDK background processing. Previously some tasks were kept running which could have lead to race conditions. (#613)

This patch release fixes minor issues with the recently-exposed Bolt11Invoice
type in bindings.
- The
Bolt11Invoice::descriptionmethod is now exposed asBolt11Invoice::invoice_descriptionin bindings, to avoid collisions with a Swift standard method of same name (#576)
- The
Displayimplementation ofBolt11Invoiceis now exposed in bindings, (re-)allowing to render the invoice as a string. (#574)

This sixth minor release mainly fixes an issue that could have left the on-chain wallet unable to spend funds if transactions that had previously been accepted to the mempool ended up being evicted.
- Onchain addresses are now validated against the expected network before use (#519).
- The API methods on the
Bolt11Invoicetype are now exposed in bindings (#522). - The
UnifiedQrPayment::receiveflow no longer aborts if we're unable to generate a BOLT12 offer (#548).
- Previously, the node could potentially enter a state that would have left the onchain wallet unable spend any funds if previously-generated transactions had been first accepted, and then evicted from the mempool. This has been fixed in BDK 2.0.0, to which we upgrade as part of this release. (#551)
- A bug that had us fail
OnchainPayment::send_allin theretrain_reservesmode when requiring sub-dust-limit anchor reserves has been fixed (#540). - The output of the
logfacade logger has been corrected (#547).
- The BDK dependency has been bumped to
bdk_walletv2.0 (#551).

- The ability to set a description hash when creating a BOLT11 invoice has been added (#438).
- The ability to export pathfinding scores has been added (#458).
- The ability to request inbound channels from an LSP via the bLIP-51 / LSPS1 protocol has been added (#418).
- The
ChannelDetailsreturned byNode::list_channelsnow exposes fields for the channel's SCIDs (#444). - Lightning peer-to-peer gossip data is now being verified when syncing from a Bitcoin Core RPC backend (#428).
- The logging sub-system was reworked to allow logging to backends using the Rust
logfacade, as well as via a custom logger trait (#407, #450, #454). - On-chain transactions are now added to the internal payment store and exposed via
Node::list_payments(#432). - Inbound announced channels are now rejected if not all requirements for operating as a forwarding node (set listening addresses and node alias) have been met (#467).
- Initial support for operating as an bLIP-52 / LSPS2 service has been added (#420).
- Note: bLIP-52 / LSPS2 support is considered 'alpha'/'experimental' and should not yet be used in production.

Node::sync_walletsmanually (#508). - The ability to configure the node's announcement addresses independently from the listening addresses has been added (#484).
- The ability to choose whether to honor the Anchor reserves when calling
send_all_to_addresshas been added (#345). - The ability to sync the node via an Electrum backend has been added (#486).
- When syncing from Bitcoin Core RPC, syncing mempool entries has been made more efficient (#410, #465).
- We now ensure the our configured fallback rates are used when the configured chain source would return huge bogus values during fee estimation (#430).
- We now re-enabled trying to bump Anchor channel transactions for trusted counterparties in the
ContentiousClaimablecase to reduce the risk of losing funds in certain edge cases (#461). - An issue that would potentially have us panic on retrying the chain listening initialization when syncing from Bitcoin Core RPC has been fixed (#471).
- The

Besides numerous API improvements and bugfixes this fourth minor release notably adds support for sourcing chain and fee rate data from a Bitcoin Core RPC backend, as well as experimental support for the VSS remote storage backend.
- Support for multiple chain sources has been added. To this end, Esplora-specific configuration options can now be given via
EsploraSyncConfigtoBuilder::set_chain_source_esplora. Furthermore, all configuration objects (including the mainConfig) is now exposed via theconfigsub-module (#365). - Support for sourcing chain and fee estimation data from a Bitcoin Core RPC backed has been added (#370).
- Initial experimental support for an encrypted VSS remote storage backend has been added (#369, #376, #378).
- Caution: VSS support is in alpha and is considered experimental. Using VSS (or any remote persistence) may cause LDK to panic if persistence failures are unrecoverable, i.e., if they remain unresolved after internal retries are exhausted.
- Support for setting the
NodeAliasin public node announcements as been added. We now ensure that announced channels can only be opened and accepted when the required configuration options to operate as a public forwarding node are set (listening addresses and node alias). As part of thisNode::connect_open_channelwas split intoopen_channelandopen_announced_channelAPI methods. (#330, #366). - The
Nodecan now be started via a newNode::start_with_runtimecall that allows to reuse an outertokioruntime context, avoiding runtime stacking when run inasyncenvironments (#319). - Support for generating and paying unified QR codes has been added (#302).
- Support for
quantityandpayer_notefields when sending or receiving BOLT12 payments has been added (#327). - Support for setting additional parameters when sending BOLT11 payments has been added (#336, #351).
- The
ChannelConfigobject has been refactored, now allowing to query the currently appliedMaxDustHTLCExposurelimit (#350). - A bug potentially leading to panicking on shutdown when stacking
tokioruntime contexts has been fixed (#373). - We now no longer panic when hitting a persistence failure during event handling. Instead, events will be replayed until successful (#374). ,
- The LDK dependency has been updated to version 0.0.125 (#358, #375).
- The BDK dependency has been updated to version 1.0-beta.4 (#358).
- Going forward, the BDK state will be persisted in the configured
KVStorebackend. - Note: The old descriptor state will not be automatically migrated on upgrade, potentially leading to address reuse. Privacy-concious users might want to manually advance the descriptor by requesting new addresses until it reaches the previously observed height.
- After the node as been successfully upgraded users may safely delete
bdk_wallet_*.sqlitefrom the storage path.
- Going forward, the BDK state will be persisted in the configured
- The
rust-bitcoindependency has been updated to version 0.32.2 (#358). - The UniFFI dependency has been updated to version 0.27.3 (#379).
- The
bip21dependency has been updated to version 0.5 (#358). - The
rust-esplora-clienthas been updated to version 0.9 (#358).

- Support for creating and paying BOLT12 offers and refunds has been added (#265).
- Support for Anchor channels has been added (#141).
- Support for sourcing inbound liquidity via LSPS2 just-in-time (JIT) channels has been added (#223).
- The node's local view of the network graph can now be accessed via interface methods (#293).
- A new
next_event_asyncmethod was added that allows polling the event queue asynchronously (#224). - A
default_configmethod was introduced that allows to retrieve sane default values, also in bindings (#242). - The
PaymentFailedandChannelClosedevents now includereasonfields (#260). - All available balances outside of channel balances are now exposed via a unified
list_balancesinterface method (#250). - The maximum in-flight HTLC value has been bumped to 100% of the channel capacity for private outbound channels (#303) and, if JIT channel support is enabled, for inbound channels (#262).
- The fee paid is now exposed via the
PaymentSuccessfulevent (#271). - A
statusmethod has been added allowing to retrieve information about theNode's status (#272). Nodeno longer takes aKVStoretype parameter, allowing to use the filesystem storage backend in bindings (#244).- The payment APIs have been restructured to use per-type (
bolt11,onchain,bolt12, ..) payment handlers which can be accessed via correspondingNode::{type}_paymentmethods (#270). - Fully resolved channel monitors are now eventually moved to an archive location (#307).
- The ability to register and claim from custom payment hashes generated outside of LDK Node has been added (#308).
- Node announcements are now correctly only broadcast if we have any public, sufficiently confirmed channels (#248, #314).
- Falling back to default fee values is now disallowed on mainnet, ensuring we won't startup without a successful fee cache update (#249).
- Persisted peers are now correctly reconnected after startup (#265).
- Concurrent connection attempts to the same peer are no longer overriding each other (#266).
- Several steps have been taken to reduce the risk of blocking node operation on wallet syncing in the face of unresponsive Esplora services (#281).
