Arbitrum Nitro v3.3.0 Release Candidate 1

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.3.0-rc.1-a81da40

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:v3.3.0-rc.1-a81da40-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

What's Changed

This release makes miscellaneous improvements to the batch poster, Stylus execution, block validation, and merges in upstream go-ethereum v1.14.0.

Configuration Changes

• --execution.caching.stylus-lru-cache has been replaced by --execution.caching.stylus-lru-cache-capacity which is now measured in megabytes.
• --blocks-reexecutor.blocks-per-thread has been renamed to --blocks-reexecutor.min-blocks-per-thread
• --chain.info-ipfs-url and --chain.info-ipfs-download-path have been removed, however, they were already nonfunctional in previous releases.
• --node.block-validator.redis-validation-client-config.producer-config.* no longer has the enable-reproduce, check-pending-interval, keepalive-timeoutandcheck-pending-items` config options.
• --validation.arbitrator.redis-validation-server-config.consumer-config.keepalive-timeout has been removed.
