Arbitrum Nitro v3.5.0-rc.3

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.5.0-rc.3-4d43771

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:v3.5.0-rc.3-4d43771-validator which has the extra script /usr/local/bin/split-val-entry.sh as the entrypoint.

What's Changed

Various timeboost related changes

Internal Highlights

• Mark timeboost options as dangerous since timeboost is a work in progress: #2928
• Fix reading of pending ExpressLane messages from redis: #2926

Arbitrum Nitro v3.5.0-rc.1

This release is available as a Docker Image on Docker Hub at offchainlabs/nitro-node:v3.5.0-rc.1-1d9c68d

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 Nitro release adds support for Timeboost, a novel transaction ordering policy for Arbitrum chains. This includes changes to both the sequencer to add an express lane for time-advantaged transaction inclusion and a new process for managing the second price, sealed bid auction for the rights to use said express lane.
