This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v2.2.0-f7dc9de

This release will be required for the Arbitrum Sepolia testnet, and should the ArbOS 11 Arbitrum DAO vote pass, this release will be required for the Arbitrum One and Arbitrum Nova mainnets mid-January. Exact details on the timelines will be released soon.

Archive Nodes

This release has issues with database compaction on archive nodes. It's highly recommended to upgrade to v2.2.1.

ArbOS 11

This release adds support for ArbOS 11, which includes EVM Shanghai support and the PUSH0 opcode. The Arbitrum DAO forum proposal documents the full extent of the upgrade. This release will be a required upgrade for any Arbitrum networks that chose to adopt ArbOS 11.

What's Changed

This release adds support for ArbOS 11, significantly improves batch poster performance, and continues splitting the execution and consensus parts of the node.

Configuration Changes

  • The --node.caching.*, --node.forwarder.*, --node.forwarding-target, --node.parent-chain-reader.*, --node.rpc.*, --node.tx-lookup-limit, --node.sequencer.*, --node.tx-pre-checker.*, and --node.recording-database flags have all been moved from --node.* to --execution.*. E.g. --node.caching.archive is now --execution.caching.archive.
  • If you were running a sequencer with --node.sequencer.enable, you must now specify both --execution.sequencer.enable and --node.sequencer.
  • The --node.archive flag was deprecated for a while as it was being moved, and it has now been removed in favor of --execution.caching.archive.
  • If you're running your node outside of docker and haven't downloaded the WASM machine files necessary for validation, you may need to add --validation.wasm.enable-wasmroots-check=false to your config.
