OffchainLabs/nitro v3.1.0-rc.1

Arbitrum Nitro v3.1.0 Release Candidate 1

on GitHub

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.1.0-rc.1-2c1feee

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:v3.1.0-rc.1-2c1feee-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

What's Changed

This release candidate adds support for ArbOS 31 and a new Anytrust filestore layout compared to v3.3.4-beta.1.
