The asymmetry between attackers and maintainers shouldn't decide bitcoin's security.

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

📣 BDK Wallet 2.4 was released today! This release focuses on back porting migration support and event system enhancements from the 3.0 release. Key additions include get_pre_v1_wallet_keychains migration helper for upgrading from pre-1.0 bdk sqlite databases, new event tracking methods (apply_unconfirmed_txs_events, apply_evicted_txs_events), and an events_helper function for advanced event handling. The wallet::signer module deprecation from 2.3 has been reverted until the new PSBT signer is ready. See all the details here:

📣 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:
