What's Changed
The version add 4844 support to the SequencerInbox and OneStepProof contracts, and is the version used in ArbOS 20 “Atlas” upgrade AIP. When upgrading from a version before 1.2.0, SequencerInbox.postUpgradeInit MUST be called with the upgradeTo call due to a storage change. ChallengeManager.postUpgradeInit is also required to set the new osp.
