OffchainLabs/nitro v3.0.3-rc.1

Arbitrum Nitro v3.0.3 Release Candidate 1

on GitHub

This release is available as a Docker image on Docker Hub at offchainlabs/nitro-node:v3.0.3-rc.1-3ecd01e

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:v3.0.3-rc.1-3ecd01e-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

What's Changed

This release fixes batch posting for Anytrust DAS chains, and fixes the optional Stylus program lazy recreation feature.

User-facing Improvements

• Add option to disable posting new batches in dataposter (useful for clearing out current batches from mempool without posting more): #2395
• Split envvars with commas in them into a slice: #2407
  • This allows for specifying e.g. --validation.wasm.allowed-wasm-module-roots as an environment variable instead of as a CLI option or JSON configuration option.
• Adds additional metrics to the batch-posting path: #2369

Internal Highlights

• Remove sig from DAS writer iface, sign in client: #2433
• Fix lazy asm recreation: #2408
• Use persisted basefee in txProcessor hooks and ArbGasInfo precompile when basefee is lowered to 0: #2358
• Define a Filesystem Cache for BOLD Machine Hash Computations: #2391
• Work around duplicate response from CL: #2432
• Consensus/Execution split: simplifies ConsensusSequencer and ExecutionEngine interfaces: #2415
