Offchain Labs has published version 3.11.1 of the Arbitrum Nitro node software. The update is available as a Docker image on Docker Hub and includes the same default configuration that the official entrypoint uses.
The image is tagged `offchainlabs/nitro-node:v3.11.1-8512b8c`. Users can pull it with `docker pull offchainlabs/nitro-node:v3.11.1-8512b8c` and run it directly, or embed it in CI/CD pipelines.
The entrypoint sets default flags that point the node to the allowed WASM module roots: `/usr/local/bin/nitro --validation.wasm.allowed-wasm-module-roots /home/user/nitro-legacy/machines,/home/user/target/machines`. If a custom entrypoint is used, these flags should be replicated to maintain the same validation behavior.
Validators that do not use a split validation server—most validators in production—should use the `offchainlabs/nitro-node` image and rely on the default flags. The split validation server is typically only required for specialized setups that separate validation logic from the main node.
The release notes are available on GitHub, and developers can review the full changelog for any additional changes. The new Docker image simplifies deployment and ensures consistency across environments.
