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).
