Arbitrum Nitro v2.2.0 Alpha 1

on GitHub

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v2.2.0-alpha.1-fdd098e

What's Changed

This release continues work on the execution split, and has many improvements, such as allowing chains to increase the contract size limit and adding a --dev flag to the node to easily spin up a local dev 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.
