In November 2025, Pi-Squared-Inc/evm-semantics delivered two high-impact enhancements to the EVM semantics, strengthening cost modeling, contract capabilities, and readiness for future standards. The Osaka schedule was introduced into the EVM semantics, enabling a richer gas-cost model and operation rules that support future features and more accurate contract execution costs. Separately, the CLZ opcode (per EIP-7939) was added, expanding 256-bit bitwise operations and enabling new algorithms that rely on count-leading-zeros. These changes improve cost predictability, performance modeling, and capability parity with evolving Ethereum standards, while laying groundwork for upcoming optimizations and feature work. Commit references tie the work to specific milestones and issues for traceability.
