0.42.0 - 2026-05-15

Highlights

This is a large release that reworks the SPV client, wallet, and FFI surface. The most impactful changes:

  • Sync architecture rewrite: the block, filter, and masternode sync pipelines were rewritten end-to-end, with explicit state machines, hardened reconnect and resume paths, deadlock fixes, and a long tail of correctness fixes around filter batching, in-flight state on disconnect, and post-sync header handling (#411, #440, #451, #452, #738).
  • dashd integration tests: end-to-end SPV sync tests against a real regtest dashd covering sync, restarts, disconnections, transactions, masternodes, and multi-wallet, gating the spv and ffi CI groups (#464, #697, #740).
  • Mempool support: a real mempool path through the SPV client with a --mempool-strategy CLI argument, plus a CoinSelector that can spend mempool UTXOs, driving a new transaction confirmation lifecycle (#558, #540, #552, #748).
  • Hardcoded masternode seeds: vendored masternode seed files with weekly CI auto-refresh so cold-start bootstrapping no longer waits for a full QRInfo sync (#678).
  • Wallet manager extraction and atomic events: core transaction building and signing moved into a dedicated wallet manager, wallet events are now atomic, and per-account balance diffs are carried on events (#594, #727, #696, #706).
  • FFI surface expansion: full TransactionRecord exposed through FFI and wallet events, asset-lock builder, MasternodeListEngine accessor, transaction broadcast, error callback registration, and an async Signer trait for iOS workflows (#614, #600, #608, #458, #661).
  • Platform and Asset Lock: a new PlatformPayment managed account to track Platform balances, plus Asset Lock derivation subfeatures 4 and 5 and a corrected AssetLockTx structure (#365, #368, #454, #659).
  • no-std support dropped: incomplete no-std support was removed across dashcore, hashes, internals, and key-wallet to simplify the codebase (#518, #519, #520, #521).

0.28 - 2022-04-20 "The Taproot Release"

At nearly nine months, this is our longest release cycle ever, and thanks to a huge increase in the number of active contributors this year and last, it is also by far our largest release ever, at 148 PRs merged from 23 different contributors. Our primary goal in this release was to introduce support for Taproot and its associated data structures: addresses, taptrees, sighashes, PSBT fields, and more. As it turned out, these changes required (or at least, incentivized) changing a lot of our APIs, causing a significant increase in scope.

We have more big changes coming down the pike. 2022 is going to be a big year for rust-bitcoin, which we know is exciting for us but disruptive to downstream users who ultimately want the library to just work. Our hope is that by 2023 we will have eliminated large amounts of technical debt, modernized our APIs to meet current Rust conventions, and clarified the scope of the individual crates in this ecosystem while still providing the essential functionality needed by our downstream users, especially wallet projects.

We will also develop a plan to make our releases more predictable and manageable, likely by having scheduled releases with limited scope. We would like to reach a point where we no longer have frequent breaking releases, but right now we are nowhere close.

Upcoming changes will include

  • A quick new release which updates our MRSV from 1.29 to 1.41 and does little else
  • Updating our codebase to take advantage of the new MSRV, especially regarding nostd and wasm support
  • A comprehensive rethinking and flattening of our public-facing APIs
  • Richer support for PSBT, Script, and BIP-0340/Schnorr signatures

With so many changes since 0.27, we cannot list every PR. Here are the highlights:

Additionally we made several minor API changes (renaming methods, etc.) to improve compliance with modern Rust conventions. Where possible we left the existing methods in place, marked as deprecated.

0.27 - 2021-07-21

0.26.2 - 2021-06-08

The previous release changed the behavior of Display for ChildNumber, assuming that any correct usage would not be affected. Issue 608 goes into the details of why this isn't the case and how we broke both rust-miniscript and BDK.
