February 2026 monthly summary for wasmtime focusing on feature delivery and business impact. Delivered the WebAssembly Operator Cost Configuration System for wasmtime, centralizing operator-level fuel costs and enabling per-operator cost customization across Cranelift and Winch backends. Introduced OperatorCostStrategy and OperatorCost, wired into Config::operator_cost and wasmtime-environ tunables, enabling Default behavior or a per-operator Table cost map. This unifies cost calculation, reduces duplication, and improves cost predictability and tunability for WebAssembly execution. Prepared groundwork for future cost-based scheduling and resource budgeting. Adjusted internal drop semantics to support non-trivial destructors in Tunables and updated tests accordingly for non-const fns in critical paths.
