- If available, peer information is now persisted for inbound channels (#170).
- Transaction broadcasting and fee estimation have been reworked and made more robust (#205).
- A module persisting, sweeping, and rebroadcasting output spends has been added (#152).
## Bug Fixes

# 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).

# 0.1-alpha - Apr 27, 2023
This is the first alpha release of LDK Node. It features support for sourcing
chain data via an Esplora server, file system persistence, gossip sourcing via
the Lightning peer-to-peer network, and configurable entropy sources for the
integrated LDK and BDK-based wallets.

production, and no compatibility guarantees are given until the release of 0.1.
