Highlights
42 commits since v0.5.1112 — a broad Node.js + TypeScript parity push: language-correctness fixes (assignment evaluation order, arrow binding, default-param TDZ, new.target), more Node built-in surface (Atomics, Intl, X509, child_process options, web stream adapters), and runtime prototype/reflection fixes.
