+All fault proof enabled chains (both permisionless and permissioned fault proof systems) need to update their `op-challenger` binary to [`op-challenger/v1.3.1`](https://github.com/ethereum-optimism/optimism/releases/tag/op-challenger%2Fv1.3.1).

 The following steps are to update your absolute prestate with new dispute game contracts. **This is absolutely necessary for chains running permissionless fault proofs.** For chains running the Fault Proof System with permissioned games you can skip this section because games will not be played out and the absolute prestate is not used. 
 
 The Pectra upgrade changes the derivation rules, permissionless fault proof chains need to upgrade the `op-program` version used in the fault proof system to support these changes. The `op-program` version used is specified via the `faultGameAbsolutePrestate` setting, deployed as part of `FaultDisputeGame` and `PermissionedDisputeGame` contracts.

   ### Verify the new absolute prestate
 
   The absolute prestate is generated with the [op-program/v1.5.0-rc.2](https://github.com/ethereum-optimism/optimism/tree/op-program/v1.5.0-rc.2). You can use this new absolute prestate (`0x035ac388b5cb22acf52a2063cfde108d09b1888655d21f02f595f9c3ea6cbdcd`) for the following chains:

 ## Design principles for USEful software
 
 The OP Stack is USEful software. The OP Stack is a set of software components for building L2 blockchain ecosystems, built by the Optimism Collective to power Optimism.
-Components to be added to the OP Stack should be built according to three key design principles: **U**tility, **S**implicity, **E**xtensibility.
-Software that follows these principles is **USE**ful software for the Optimism Collective!
