Arbitrum Nitro v3.6.0-rc.2

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.6.0-rc.2-608725a

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:v3.6.0-rc.2-608725a-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

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

What's Changed

This is the first version of Nitro with support for the features in Pectra https://eips.ethereum.org/EIPS/eip-7600
This release includes updates to the nitro fork of go-ethereum equivalent to v1.15.5.

Purposefully NOT included in this release are these 4 EIPs related to supporting consensus-layer client operations like deposits, withdrawals, and consolidation since Arbitrum uses a very different consensus mechanism which does not rely on proof of stake:

• EIP-6110: Supply validator deposits on chain
• EIP-7002: Execution layer triggerable exits
• EIP-7251: Increase the MAX_EFFECTIVE_BALANCE
• EIP-7685: General purpose execution layer requests

Support for EIP-7623 (increased calldata cost) has been added, but hidden behind a new ArbOwner precompile method setCalldataPriceIncrese(bool) which is disabled by default. Contract Code
