OffchainLabs/nitro v3.8.0-rc.1

Arbitrum Nitro v3.8.0-rc.1

on GitHub

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.8.0-rc.1-3ca9e30
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:v3.8.0-rc.1-3ca9e30-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

User facing changes

• Important! If you have previously used the ArbOwner.setMaxTxGasLimit to set the max transaction and block gas limits for your chain, you should add calls to ArbOwner.setMaxTxGasLimit and ArbOwner.SetMaxBlockGasLimit to your upgrade action to arbos 50. (When it's time.)
• After the arbos 50 upgrade, there is a new ArbOwner.setL1CalldataPrice which can be used to set the parent chain's blob base fee per byte of caldata. This is for allowing the state transition function to adjust for the parent chain having enabled EIP-7623: Increase calldata cost

Highlights

• Nitro is ready for Fusaka
• Arbitrum One node operators need to upgrade to v3.8.0 before mainnet upgrades to Fusaka
• Arbitrum One and Arbitrum Nova will both upgrade to ArbOS 50 as described in the AIP
