Arbitrum Nitro v2.4.0 Release Candidate 1

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v2.4.0-rc.1-3deb9ca

This Docker image specifies new 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, you should instead use the image offchainlabs/nitro-node:v2.4.0-rc.1-3deb9ca-validator

What's Changed

This release fixes some miscellaneous issues compared to the last beta release.

User-facing Improvements

• feat(das): add support to configure http body limit: #2321

Internal Highlights

• Allow 0x prefix for allowed-wasm-module-roots flag: #2338
• Implement tracing and CPU profiling of long running block creations: #2305
• Create streams in redis client, poll on it in redis-server: #2303
