July 2025 monthly summary for matter-labs/zksync-airbender: Implemented RISC-V simulator state standardization and interface unification. Refactored the RISC-V simulator state to adhere to the RISC-V32Machine trait and introduced RISCV32ObservableState to standardize state access across simulator backends, including the new unrolled prover. This work enhances interface consistency, maintainability, and cross-backend integration, laying the groundwork for future prover integrations and performance improvements.

November 2024 monthly summary for matter-labs/zksync-crypto focusing on build system simplification and cross-platform stability improvements. Key achievements delivered a streamlined Rust toolchain build by removing the obsolete const_slice_index feature gate, stabilizing the feature and merging it into the main Rust distribution, thereby reducing build complexity and ongoing maintenance. On macOS, stabilized the Darwin toolchain by disabling NEON vectorization and replacing the arm_asm_impl module with a generic_impl, improving compatibility and overall stability on macOS across environments. Commits highlighted: - refactor: Remove `const_slice_index` feature gate (#49) — 09ca79c6f9d731d225ed31fcaf0572794fdb3146 - fix: Disabled vectorisation for neon (#52) — 3900a4b4b225545e9cc05ad7ebca570aac3dd300
