Arbitrum Nitro v3.11.1

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.11.1-8512b8c
This Docker image specifies default flags in its entrypoint which should be replicated if you're overriding the entrypoint: /usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines\

If you're running a validator without a split validation server (this will be true of most validators), you should instead use the image offchainlabs/nitro-node:v3.11.1-8512b8c-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

v3.11.1 - 2026-06-29

Fixed

• The Stylus warm-start cache is now rolled back when a transaction is dropped after executing. [commit]
• Use mutex for history reads [commit]

Arbitrum Nitro v3.11.0

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.11.0-a618155
This Docker image specifies default flags in its entrypoint which should be replicated if you're overriding the entrypoint: /usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines\

If you're running a validator without a split validation server (this will be true of most validators), you should instead use the image offchainlabs/nitro-node:v3.11.0-a618155-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

v3.11.0 - 2026-06-22

Added

• ArbOS60 supported.
• Add --execution.legacy-zero-base-fee-until restores the pre-v3.7 behavior of treating headers with ArbOSFormatVersion <= 40 and BaseFee == 0 for affected chains.
• Add --execution.transaction-filtering.enable replaces --execution.address-filter.enable.
• Sequencer reports filtered regular transactions to the filtering-report service via FilteringReportRPCClient.
• Unified replay binary (cmd/unified-replay/) combining MEL message extraction and block production into a single WASM-compilable program.
• GetEndParentChainBlockHash host I/O opcode for MEL proving.
• melwavmio package providing WASM imports and native stubs for MEL.
• Extended GlobalState to 4 bytes32 slots with backward-compatible hashing.
• Makefile targets build-unified-replay-env and build-unified-wasm-bin.
• Sign outbound webhook payloads from cmd/filtering-report with an Ed25519 leaf certificate issued by an internal CA, so receivers verify the signature against the CA root and rotate keys transparently.
• Add scripts/rust-val-entry.sh Docker entrypoint script that launches a single Rust validation server alongside the nitro node.
• Add nitro-node-rust-validator Docker target.
• Support for ArbOS 61.
• Add per-worker slowdown on consecutive retryable HTTP errors from the external endpoint to avoid hammering a degraded service and consuming max receive count quota unnecessarily.
• Download the consensus-v61-rc.1 replay machine in the Docker build.

Changed

• S3SyncManager now includes filterSetID in the successful hash-list load log line so operators can correlate it with the FilterSetID reported on filtered tx reports.
• Replace sha3/digest keccak with tiny-keccak across prover and caller-env.
• --node.transaction-streamer.shutdown-on-blockhash-mismatch now defaults to true: on a feed-vs-local block hash mismatch the node refuses to persist or rebroadcast the result and shuts down gracefully.
• Update README.md with support policy.
• Update CONTRIBUTING.md with the new development process.
• Reduced GC frequency for in replay binary (for wasm targets).
• Use Option for interface vars that can be empty.

Fixed

• Skip extra header columns in iostat parsing.
• Improve locking mechanism in backlogSizeInBytes().
• Reduce log spam during node sync. ExecuteNextMsg now throttles accumulator not found errors via an ephemeral error handler.
• Iterator leak in deleteWasmEntries: defer is now late-bound so the post-flush iterator is released.
• Allow retrying --init.url after a prior init created the wasm/ subdirectory but did not complete chain initialization.
• Fixed initialization of redis-validator.
• Re-run genesis assertion validation on startup while the chain head is still at genesis, so a previously failed validation is not silently skipped on subsequent restarts.
• Canonicalize NaN values returned by soft-float library functions so WAVM and JIT produce identical results when floating-point operations yield NaN.
• Fixed honest-validator self-challenge bug in BoLD where a slow catchup goroutine could downgrade latestAgreedAssertion
• ArbOS 61: skip multi-gas refund when no constraints are configured.
• ArbOS 61: use block basefee for the SingleDim refund override.
• ArbOS 61: account for EVM SSTORE refunds in the multi-gas refund.
• Stylus pre-VM OOG: when contract.BurnGas(callCost) drains the call frame before WASM runs, attribute the residual to WasmComputation so receipt.MultiGasUsed.SingleGas() matches receipt.GasUsed.
• Updated log.* calls to use slog key/value pairs.
• Address filter now records the L1 destination of ArbSys.withdrawEth / ArbSys.sendTxToL1 via a new ReasonToL1, closing a gap where L2→L1 withdrawals to a filtered address were not caught.
• Fix invalid Prometheus metric names in filtering-report and transaction-filterer components; hyphens in geth metric paths survive the /→_ translation and produce names that violate the Prometheus spec.
• Removed legacy validator (was included but not working since wasmer upgrade).
• Removed unnecessary tokens from consensus machine downloads in Dockerfile.
• pin nitro-testnode master branch.
• Sequencer no longer rejects clean transactions following a filtered one in the same block. PreTxFilter now operates on a fresh per-tx addressCheckerState instead of inheriting the previous tx's filter state.
• Do not combine multi-gas refunds with EVM refunds.

Internal

• stylus-raw-deploycode - a small utility that helps deploy stylus contracts for testing.
• Make validation crate no-std friendly.
• Remove JIT wrappers for wasi and wavmio.
• Fix inner call and pushcontract address filter recording
• cmd/filtering-report forwarder now emits an info log on successful report forwarding and includes the SQS message body in the existing forward-failure error log.
• NIT-5012: fail fast when delayed-sequencing filtering is active but transaction-filterer-rpc-client.url is unset, and pin the transaction-filterer binary to serve only the transactionfilterer RPC namespace.
• Make GuestPtr field private with checked addition (panics on overflow instead of silent wraparound).
• Remove JIT wrappers for arbcrypto and arbcompress.
• Address-filter S3 hash list now expects the upstream latest.json schema
• Address-filter HashStore now supports hashing_scheme: "sha256-rawbytesinput"
• Optional --execution.transaction-filtering.address-filter.s3.max-file-size-mb flag
• The transaction prechecker now reports address-filtered transactions to the filtering-report service.
• Send non-retryable HTTP errors to an optional poison queue for manual inspection or reprocessing.
• Include transaction-filterer binary in nitro-node and nitro-node-stripped Docker images.
• Report filtered delayed transactions to filtering-report service with structured FilteredTxReport.
• Add script to generate large filtered-addresses-hashed-list.json test fixtures.
• Refactor filtering report test infrastructure: rename CheckReportBlockNumberAndParentBlockHash to CheckCommonReportFields with additional common assertions and update SetupFilteringReport to return the RPC stack.
• Remove -A static_mut_refs from clippy invocation in CI (we do not use mutable statics anymore).
• Add forge version validation to scripts/check-build.sh.
• Cache hash keys for MultiGasFees substorage.
• Add FilterSetID field to FilteredAddressRecord and expose it through the AddressChecker and StateDB interfaces so callers can stamp each record with the active filter set id.
• EnableETHCallFilter now scopes to eth_estimateGas only; no longer gates prechecker filtering.
• Set default EnableETHCallFilter to false.
• Skip prechecker transaction-filter dry-run on sequencer nodes.

Arbitrum Nitro v3.10.2

Important Note: Once a database is run with v3.10.x, the database cannot be used with v3.9.9.

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.10.2-db30ef0
This Docker image specifies default flags in its entrypoint which should be replicated if you're overriding the entrypoint: /usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines\

Special note: On Monday, May 18, 2026 at 17:00 UTC, ArbOS 60 will activate on the Arbitrum Sepolia chain. Arbitrum Sepolia node operators must upgrade to Nitro v3.10 ahead of this activation to continue syncing the chain. This is not a required upgrade for Arbitrum One at this time, the date for Arbitrum One ArboOS upgrade has not been set yet.

Sepolia validators can use block-validator.pending-upgrade-module root="0x7a9e6a77354888257a9989ce0b6bb39df5fedf222d453932933fdf7a489cbb57" to validate against the planned arbos-60 upgrade

Important for any chains still on ArbOS40:

• Any chain running ArbOS40 can upgrade non-validator nodes to latest version.
• Any chain running ArbOS40, upgrading validators to Nitro v3.10.x needs to update module root to Consensus v60-rc.4 at the same time.  Do NOT perform ArbOS upgrade to ArbOS60, only ArbOS5x.
• If a chain is on ArbOS40 and has already upgraded validators to v3.10.x, the module root should be updated to Consensus v60-rc.4 as soon as possible. Do NOT perform ArbOS upgrade to ArbOS60, only ArbOS5x.

v3.10.2 - 2026-06-02

Configuration

• Add --execution.transaction-filtering.enable master switch (default false), replaces --execution.address-filter.enable.

Fixed

• Improve BoLD assertion poster logs.
• Fixed initialization of redis-validator.

Added

• NIT-4804: address-filter now supports hashing_scheme: "sha256-rawbytesinput"

• Validator should use configuration option --node.block-validator.pending-upgrade-module-root="" to avoid performing unnecessary work trying to validate consensus_v51.1.

v3.10.1 - 2026-05-12

Configuration

• Add --execution.legacy-zero-base-fee-until <unix-ts> opt-in compatibility flag (default 0 = disabled). When set, restores the pre-v3.7 behavior of treating headers with ArbOSFormatVersion <= 40 and BaseFee == 0 as non-arbitrum, for blocks with timestamp strictly less than the given value.

Added

• Include transaction-filterer binary in nitro-node and nitro-node-stripped Docker images.

Changed

• Set default EnableETHCallFilter to false.
• Update address-filter S3 hash list format
• Ensure genesis block is appropriately validated

Fixed

• Resolve BoLD Staking Bug That Attempts Self-Challenge

Arbitrum Nitro v3.10.0

Important Note: v3.10.0 should not be used to run staking validator

Important Note: Once a database is run with v3.10.0, the database cannot be used with v3.9.9.

Important Note: Please add this option to nodes running v3.10:
execution.transaction-filtering.enable-ethcall-filter=false
The default doesn't make anything behave incorrectly, but it does a lot of unnecessary work for the sequencer and for precheckers/forwarders.
We will fix the default on future versions.

Arbitrum Nitro v3.10.0-rc.10

Release candidates should not be run in general

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.10.0-rc.10-b1cf6db
This Docker image specifies default flags in its entrypoint which should be replicated if you're overriding the entrypoint: /usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines

Important for any chains still on ArbOS40:

• If you're running a validator without a split validation server (this will be true of most validators), you should instead use the image offchainlabs/nitro-node:v3.10.0-rc.10-b1cf6db-validator which has the extra script /usr/local/bin/split-val-entry.sh as the default entrypoint (no need to override the default entrypoint). This will run both v3.10.0 and v3.7.6 validator workers for you.
• If you are using a split validator, you do not want to use -validator image, you need to run a validator worker on v3.7.6 as well as a worker for v3.10.0

Important for any chains that previously upgraded to ArbOS51 with consensus_v51

• Validator should use configuration option --node.block-validator.pending-upgrade-module-root="" to avoid performing unnecessary work trying to validate consensus_v51.1.
