BDK bindings 3.1.0 are out! Custom signers, coin selection, multipath descriptors & more, built on bdk_wallet 3.1.0

https://github.com/bitcoindevkit/bdk-ffi/releases#release-v3.1.0

📢 Version 4.0.0 of BDK CLI has been released! This release introduces experimental support for creating silent payment transactions and adds support for BIP-353 DNS payment instructions. It also adds UTXO locking through new wallet commands. Async payjoin sessions are now persisted to SQLite, so interrupted payjoin sessions can be resumed. The release also includes internal refactoring that improves readability and makes adding new commands easier and less prone to errors. It also updates the Wallet API to v3.1.0 amongst other improvements.

Massive thanks to all the contributors that made this release possible and especially to

for being the bdk-cli maintainer and delivering this release.

A thing of beauty should always get a closer look :-)

📣 BDK Wallet 3.0 was released two weeks ago but forgot to announce it, so here you go!

This release introduces major API changes including persistent UTXO locking, structured wallet events, and adopts NetworkKind throughout the codebase for improved network handling.

It also adds support for Caravan wallet format import/export and includes a special migration utility for SQLite databases existing prior to version 1.0. Documentation and test coverage have been expanded, along with several quality of life improvements.

Note: This release includes new persisted data for tracking UTXO lock statuses. The change is backwards compatible if you use the standard sqlite datastore. But if you've build a custom Wallet datastore you'll need to update your code to support the new data.

See all the details here:
