    Release notes

    Consensus & Network

    • Only arm a peer stall deadline for a getblocks with a non-zero stop hash. An open-ended getblocks needs no reply, so the deadline disconnected honest, fully-synced peers (btcsuite/btcd#1317).
    • Stop replying to getblocks with an empty notfound when pruned.
    • Fix a hang on shutdown caused by a blocking queue send to a peer that had already quit.
    • Always signal the send completion channel when serving a merkle block, which could otherwise wedge a peer's input handler.
    • Fix two data races in the connection manager on ConnReq.Addr.
    • Log a warning when a transaction is relayed to no peer, which happens when its fee rate is below every peer's fee filter.

    Mining

    • Pad the coinbase to the minimum transaction size enforced at the block height. Block generation was permanently broken on regtest above height 1000 and simnet above 3000.
    • Set the Upgrade9 behavior flag in CheckConnectBlockTemplate, which rejected valid CashToken transactions in getblocktemplate.

    RPC & gRPC

    • Match transaction subscriptions on the address funding an input, so spends of outputs the subscription did not watch arrive now notify. Confirmed parents require --txindex.
    • Report the missing parent rather than "already have transaction" when submitting a transaction held in the orphan pool, matching BCHN.
    • Make the estimatefee nblocks parameter optional, matching BCHN and Bitcoin ABC 0.19.1.

    Database

    • Fix a panic when a block rolls the block store over to a new flat file. The panic was recovered while the file lock was held, leaving the database wedged rather than crashing.

    Security

    • Fix a CashTokens consensus rule violation allowing minting NFT forgery. The authorization check shared one flag across all output categories, so a single authorized minting output authorized every other one in the same transaction. Reported by 0xaudron.
    • Fix a remotely triggerable crash in the committed filter handlers, which dereferenced a missing index. --fastsync also advertised NODE_CF without maintaining one.
    • Reject raw transactions with trailing bytes in decoderawtransaction and sendrawtransaction, which were previously discarded and the transaction relayed.

    Build & Packaging

    • Publish the Docker image to GHCR on each release tag.
    • Rewrite the deprecated io/ioutil usage go-bindata emits, with a make bindata target so it survives regeneration.
    • Update dependencies, including google.golang.org/grpc, golang.org/x/crypto, and golang.org/x/net.

    Other

    • Export bchec.ErrInvalidSquareRoot for use with errors.Is.
    • Modernize loops to range over integers, and adopt slices.Backward and strings.Builder.
    • Assert the CHIP-2021-05 hashing density limit in the VM limits tests, which previously carried a check that could never execute.
    • Fail rather than skip in the invalid VMB vector tests when a vector executes without error.
    • Fix flaky address manager tests by generating only routable addresses.
    • Removed support for plan9.

  9. v0.22.130 Jun 2026
    Release notes

    Consensus & Network

    • Remove the defunct dnsseed.electroncash.de DNS seed.

    Mining

    • Include the Upgrade9 (CashTokens) script flags when building block templates. Templates were previously validated with the bare StandardVerifyFlags, so on token-active networks valid CashToken transactions already in the mempool were dropped from the template, producing empty or near-empty blocks; the flags are now computed the same way the mempool and consensus block validation do.

    Other

    • Modernize sync/atomic usage with the typed atomic APIs and adopt WaitGroup.Go.

  13. v0.22.023 Apr 2026
    Release notes

    This release adds support for the May 15, 2026 Bitcoin Cash network upgrade ("upgrade12"). All node operators must upgrade before activation to stay in consensus.

    What's new

    • CHIP-2021-05 — Bounded looping operations (OP_BEGIN / OP_UNTIL)
    • CHIP-2025-05 Functions — Function definition and invocation (OP_DEFINE / OP_INVOKE)
    • CHIP-2025-05 Bitwise — Re-enables OP_INVERT, OP_LSHIFTNUM, OP_RSHIFTNUM, OP_LSHIFTBIN, OP_RSHIFTBIN
    • CHIP-2024-12 P2S — Pay-to-Script standardization
    • VMB test vectors for all of the above

    Activation

    Network MTP activation
    Mainnet / testnet3 / testnet4 2026-05-15 12:00 UTC
    Chipnet 2025-11-15 12:00 UTC (already active)
    Regtest / simnet always active

    Upgrade notes

    • No database migration required.
    • Pre-upgrade script types (P2PKH, P2SH20, P2SH32, etc.) continue to behave as before.
    • Upgrade before May 15, 2026 to avoid consensus divergence.

    Full Changelog: v0.21.1...v0.22.0

    • Implement CHIP-2021-05 Loops: bounded looping operations.
    • Implement CHIP-2025-05: re-enable the bitwise opcodes OP_INVERT, OP_2MUL, OP_2DIV, OP_LSHIFT, and OP_RSHIFT.
    • Align Upgrade12 consensus, policy, and VMB tests with BCHN, including corrected operation-cost accounting.

    Security

    • Fix CVE-2018-17145 (inv-message memory-exhaustion denial-of-service vector).

    Build & Packaging

    • Bump the Dockerfile to the latest Go release and trim the Docker build context.

    Other

    • Add VMB (VM bytecode) test vectors for the May 2026 upgrade covering bitwise ops, loops, functions, and P2S.

    Release notes2 sources agree

    Consensus & Network

    • Avoid connecting to Bitcoin ABC nodes and prevent the connection manager from dialing duplicate addresses (#450).
    • Remove the dead seed-bch.bitcoinforks.org DNS seed (#443).
    • Add a clean-shutdown check in updateSyncPeer to avoid races during node shutdown (#442).

    Mempool & Policy

    • Allow multiple OP_RETURN (null-data) outputs per transaction via a configurable policy (#467).

    Mining

    • Add a SignMuSig function to the bchec package (#457).

    RPC & gRPC

    • Add SLP gRPC/REST endpoints and fields: GetParsedSlpScript, GetTrustedValidation, GetTokenMetadata, and CheckSlpTransaction (with DisableSlpBurnErrors), plus SLP token metadata/addresses on GetTransaction, GetUnspentOutput, and the transaction subscription filters (#387, #458).
    • Validate SLP transactions by default in SubmitTransaction (clients must opt out via skip_slp_validity_check) to guard against accidental token burns (#387).
    • Add a gRPC-gateway REST/JSON proxy server (with CORS and no-cache middleware) and regenerated Swagger definitions for the bchrpc API (#387).
    • Return pubkey (P2PK) outputs from GetAddressUnspentOutputs (#432).

    Wallet & Indexing

    • Add the SLP (Simple Ledger Protocol) token index, validating SLP/NFT1 token transactions (genesis, mint, send, mint-baton tracking, burn detection) with a new --slpindex config option (#387, #452).
    • Add SLP Graph Search, building a token transaction graph to support trusted client-side validation (#451).
    • Fix index-manager handling of indexers whose StartBlock() height is greater than 0, so SLP and other late-starting indexes sync correctly (#455).
    • Refuse to start an index on a pruned node (print an error and exit) and prevent a crash when SLP index initialization fails (#433).

    Performance

    • Flush the UTXO cache during state reconstruction and correctly set lastFlushHash on init, with tests for a hard shutdown mid-flush (#445, #446, #447).

    Build & Packaging

    • Add Prometheus metrics support and per-component shutdown logging (#453).
    • Add darwin/arm64 (Apple Silicon) binary builds.
    • Add RegressionTestAnyHost and RegressionTestNoReset regtest options for Docker-based setups (#462).

    Bug Fixes

    • Fix a panic in the fee estimator triggered by chain reorgs (#434).
    • Fix a crash related to unconfirmed NFT child tokens in the gRPC server (#387).
