v0.24.0

Summary

This release contains important dependency updates for rust-bitcoin to 0.29 and rust-miniscript to 8.0, plus related crates that also depend on the latest version of rust-bitcoin. The release also includes a breaking change to the BDK signer which now produces low-R signatures by default, saving one byte. A bug was found in the get_checksum and get_checksum_bytes functions, which are now deprecated in favor of fixed versions called calc_checksum and calc_checksum_bytes. And finally a new hardware-signer features was added that re-exports the hwi crate, along with a new hardware_signers.rs example file.

Changed

  • Updated dependency versions for rust-bitcoin to 0.29 and rust-miniscript to 8.0, plus all related crates. @afilini #770
  • BDK Signer now produces low-R signatures by default, saving one byte. If you want to preserve the original behavior, set allow_grinding in the SignOptions to false. @vladimirfomene #779

  • Remove deprecated "address validators". @afilini #770

Added

  • New calc_checksum and calc_checksum_bytes, replace deprecated get_checksum and get_checksum_bytes. @evanlinjin #765

v0.20.0

  • Fix hang when ElectrumBlockchainConfig::stop_gap is zero.
  • Set coin type in BIP44, BIP49, and BIP84 templates
  • Get block hash given a block height - A get_block_hash method is now defined on the GetBlockHash trait and implemented on every blockchain backend. This method expects a block height and returns the corresponding block hash.

  • Pin tokio dependency version to ~1.14 to prevent errors due to their new MSRV 1.49.0

v0.16.0

  • Fixed generating WIF in the correct network format.

v0.15.0

  • Overhauled sync logic for electrum and esplora.
