0.7.0 - Dec. 3, 2025

This seventh minor release introduces numerous new features, bug fixes, and API improvements. In particular, it adds support for channel Splicing, Async Payments, as well as sourcing chain data from a Bitcoin Core REST backend.

Feature and API updates

• Experimental support for channel splicing has been added. (#677)
  • Note: Splicing-related transactions might currently still get misclassified in the payment store.
• Support for serving and paying static invoices for Async Payments has been added. (#621, #632)
• Sourcing chain data via Bitcoin Core's REST interface is now supported. (#526)
• A new Builder::set_chain_source_esplora_with_headers method has been added
  that allows specifying headers to be sent to the Esplora backend. (#596)
• The ability to import and merge pathfinding scores has been added. (#449)
• Passing a custom pre-image when sending spontaneous payments is now supported. (#549)
• When running in the context of a tokio runtime, we now attempt to reuse the
  outer runtime context for our main runtime. (#543)
• Specifying a RouteParametersConfig when paying BOLT12 offers or sending refunds is now supported. (#702)
• Liquidity service data is now persisted across restarts. (#650)
• The bLIP-52/LSPS2 service now supports the 'client-trusts-LSP' model. (#687)
• The manual-claiming flow is now also supported for JIT invoices. (#608)
• Any key-value stores provided to Builder::build_with_store are now
  required to implement LDK's KVStore as well as KVStoreSync interfaces.
  (#633)
• The generate_entropy_mnemonic method now supports specifying a word count. (#699)

Bug Fixes and Improvements

• Robustness of the shutdown procedure has been improved, minimizing risk of blocking during Node::stop. (#592, #612, #619, #622)
• The VSS storage backend now supports 'lazy' deletes, allowing it to avoid
  unnecessarily waiting on remote calls for certain operations. (#689, #722)
• The encryption and obfuscation scheme used when storing data against a VSS backend has been improved. (#627)
• Transient errors during bitcoind RPC chain synchronization are now retried with an exponential back-off. (#588)
• Transactions evicted from the mempool are now correctly handled when syncing via bitcoind RPC/REST. (#605)
• When sourcing chain data from a Bitcoin Core backend, we now poll for the
  current tip in Builder::build, avoiding re-validating the chain from
  genesis on first startup. (#706)
• A bug that could result in the node hanging on shutdown when sourcing chain data from a Bitcoin Core backend has been fixed. (#682)
• Unnecessary fee estimation calls to Bitcoin Core RPC are now avoided. (#631)
• The node now persists differential updates instead of re-persisting full channel monitor, reducing IO load. (#661)
• The previously rather restrictive MaximumFeeEstimate was relaxed. (#629)
• The node now listens on all provided listening addresses. (#644)

Compatibility Notes

• The minimum supported Rust version (MSRV) has been bumped to rustc v1.85 (#606)
• The LDK dependency has been bumped to v0.2.
• The BDK dependency has been bumped to v2.2. (#656)
• The VSS client dependency has been updated to utilize the new vss-client-ng crate v0.4. (#627)
• The rust-bitcoin dependency has been bumped to v0.32.7. (#656)
• The uniffi dependency has been bumped to v0.28.3. (#591)
• The electrum-client dependency has been bumped to v0.24.0. (#602)
