Arbitrum Nitro v3.9.0-rc.3

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.9.0-rc.3-cca645a
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:v3.9.0-rc.3-cca645a-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

Internal Highlights

• Add back split-val-entry: #3999

Arbitrum Nitro Consensus v50

This release signifies a WASM fraud proof consensus version, and is not a good version to run a node on

WAVM Module Root: 0x2c54f6e9e378ba320ed9c713a1d9f067a572b1437e4f1c40b1a915d3066c04f2

This is a consensus release for ArbOS 50, including support for Fusaka.

Full Changelog: consensus-v40...consensus-v50

Arbitrum Nitro v3.8.0

This release has many bug fixes and improvements. This is not a mandatory upgrade, but any nodes running v3.8.0-rc.* versions are highly encouraged to upgrade.

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.8.0-62c0aa7
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

Special Note about ArbOS 50 Support

Release v3.8.0 is unrelated to ArbOS50. A future version of Nitro that supports ArbOS50 will eventually be mandatory if the DAO votes to adopt ArbOS50, but this will be addressed later.

Special Note For Database Schema

• Nitro 3.8.0 changes the database schema, so once a database has been run with 3.8.0, the database can no longer be opened with Nitro 3.7.x.

Schema Change

• ArbOS database schema version is updated to version 2. This is a one-way upgrade and nodes may not be downgraded to a pre-v3.8.0 release without restoring their database from a backup.
