2.0.0 - 2026-06-09

BREAKING

• Upgrade blockchain_utils from ^1.4.1 to ^6.0.0. Resolves the dependency conflict reported in #20 (consumers using bitcoin_base 7.x / xrpl_dart 7.x, which require blockchain_utils ^6.0.0).
• Minimum Dart SDK raised to >=3.7.0 (required by blockchain_utils 6.0.0).

Changed

• Migrated the vendored bitcoin_base_hd and xrpl_dart forks to the blockchain_utils 6.x API: relocated utility imports to the package barrel, Tuple/item1,item2 → Dart records ($1,$2), mask*/writeUintXLE → BinaryOps.*, bytesEqual/iterableIsEqual → BytesUtils/CompareUtils, Secp256k1*KeyEcdsa → Secp256k1*Key, BitcoinSigner/BitcoinVerifier → BitcoinKeySigner/BitcoinSignatureVerifier, BigintUtils.orderLen → BigintUtils.bitlengthInBytes.
• ECDSA / Taproot / message signing outputs verified byte-for-byte identical to the pre-upgrade implementation; XRP secp256k1 family-seed derivation and classic/X-address conversion pinned with characterization tests.
• Bech32Validations / SegwitValidations declared as mixin (Dart 3 language level no longer permits using a plain class as a mixin).

Notes

• No public API changes beyond the SDK floor; all 782 unit tests pass.

2.0.1 - 2026-06-12

Added

• SC (Sia): native Go FFI transaction bridge (ScGoFfiBridge) as a faster, opt-in alternative to the WASM bridge. The default create() is unchanged and still uses the WASM bridge (ScWasmRunBridge), so existing callers are unaffected. The native library is not bundled: the caller builds it for their platform (see lib/src/forked_lib/sia-wasi/build.sh), loads it, and passes it via ScTransactionBuilder.createWithFfi(DynamicLibrary).

Changed

• Minimum Dart SDK raised to >=3.11.0 (required by the wasd WASM interpreter that backs the default SC bridge). Consumers on Dart 3.7–3.10 must upgrade.

Removed

• Pruned dead code from the vendored bitcoin_base_hd fork that is never reached by this package (BTC/LTC/BCH only use ECPrivate):
  • the entire provider/ subtree (Electrum/HTTP API providers and the BitcoinTransactionBuilder / BCH builder) and utils/btc_utils.dart (~2.2k lines).
  • ECPublic.verifyTransactionSignature and ECPublic.verifySchnorrTransactionSignature (unused; their post-upgrade bodies had latent argument-shape issues).
