OffchainLabs/nitro v3.9.4

Arbitrum Nitro v3.9.4

on GitHub

Nitro v3.9.4 is an optional release, only minor updates on top of v3.9.3.

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.9.4-7f582c3
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:v3.9.4-7f582c3-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint (no need to override the default entrypoint).

Configuration Changes

• --node.batch-poster.data-poster.enable-cell-proofs has been removed
• --parent-chain.blob-client.use-legacy-endpoint has been removed
