February 2025 — Scroll Proving SDK: Delivered a controlled dependency upgrade for RevM to scroll-evm-executor/v55 with rollback to stable state, balancing access to newer features with system reliability. The changes were implemented in scroll-tech/scroll-proving-sdk to prepare for next-scale capabilities while ensuring release readiness.

January 2025 delivered a major reliability improvement for EVM proof verification by switching from a boolean to a fallible Result return type, enabling granular error handling and richer error reporting across the SDK and CLI. The change also included dependency updates and alignment of verification logic to accommodate the new error model, resulting in clearer debugging and fewer silent failures for users and operators.
