V0.2.3 Upgrade Guide

AltLayer Mach AVS has been upgraded to v0.2.3. This release is a mandatory upgrade and we require all operators to perform the upgrade. The new features in this upgrade are:

• Extends support to Arbitrum Sepolia (Holesky) and Arbitrum One (Mainnet)

• Heath checks for operator liveness

Note: Only operators for AltLayer MACH AVS need to be upgraded. No action is needed for other MACH AVS (e.g. Xterio, DODOchain and Cyber).
