This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.2.0-f847be0
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:v3.2.0-f847be0-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.
The hash in the Docker image tag is different than this commit hash because the published commit was squashed.
What's Changed
This release contains security fixes activated by a new upgrade, ArbOS 32. The Arbitrum Security council is planning to execute an emergency action in order to activate ArbOS 32 in the coming days which is why the version upgrade is required. A binary of the release has been provided ahead of time to allow for more time to upgrade, and the source code will be made available some time before the upgrade action is taken.
If you encounter the error "cpu flags not supported on local cpu", your CPU may be missing support for standard x86 extensions. This can be resolved by adding the --execution.stylus-target.amd64=x86_64-linux-unknown+sse4.2 flag to disable use of these extensions.
