Overview

This release adds 3 Safe extensions that are intended to help OP Stack chains reach Stage 1. You can read more about this in the governance post.

Contract Changes

Only the following 3 contracts are released with the version:

• LivenessGuard, a guard for Safes
• LivenessModule, a module for Safes, intended to be paired with LivenessGuard.
• DeputyGuardianModule, a module for Safes.

These are all unrelated to the core OP Stack protocol contracts.

Full Changelog

The full contracts diff between this release and the prior release can be found at the link below. Note that, because this is a monorepo, this will likely include many unrelated changes and will be a noisy diff. Because op-contracts/v1.4.0 is also pending governance approval, this release is compared to op-contracts/v1.3.0
