v0.3.0

0.3.0 - June 21, 2024

This third minor release notably adds support for BOLT12 payments, Anchor channels, and sourcing inbound liquidity via LSPS2 just-in-time channels.

Feature and API updates

• 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_async method was added that allows polling the event queue asynchronously (#224).
• A default_config method was introduced that allows to retrieve sane default values, also in bindings (#242).
• The PaymentFailed and ChannelClosed events now include reason fields (#260).
• All available balances outside of channel balances are now exposed via a unified list_balances interface 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 PaymentSuccessful event (#271).
• A status method has been added allowing to retrieve information about the Node's status (#272).
• Node no longer takes a KVStore type 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 corresponding Node::{type}_payment methods (#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).

Bug Fixes

• 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).

Compatibility Notes

• LDK has been updated to version 0.0.123 (#291).

v0.1.0

0.1.0 - Jun 22, 2023

This is the first non-experimental release of LDK Node.

• Log files are now split based on the start date of the node (#116).
• Support for allowing inbound trusted 0conf channels has been added (#69).
• Non-permanently connected peers are now included in Node::list_peers (#95).
• A utility method for generating a BIP39 mnemonic is now exposed in bindings (#113).
• A ChannelConfig may now be specified on channel open or updated afterwards (#122).
• Logging has been improved and Builder now returns an error rather than panicking if encountering a build failure (#119).
• In Rust, Builder::build now returns a Node object rather than wrapping it in an Arc (#115).
• A number of Config defaults have been updated and are now exposed in bindings (#124).
• The API has been updated to be more aligned between Rust and bindings (#114).

Compatibility Notes

• Our currently supported minimum Rust version (MSRV) is 1.60.0.
• The superfluous SendingFailed payment status has been removed, breaking serialization compatibility with alpha releases (#125).
• The serialization formats of PaymentDetails and Event types have been updated, ensuring users upgrading from an alpha release fail to start rather than continuing operating with bogus data. Alpha users should wipe their persisted payment metadata (payments/*) and event queue (events) after the update (#130).
