This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.8.0-rc.15-f3dc927
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:v3.8.0-rc.15-f3dc927-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.
Note
This is a Release Candidate, and should only be used to upgrade nodes that are already running a previous release candidate.
Special Note about ArbOS 50 Support
Release v3.8.0-rc.14 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.
