WebAssembly's JavaScript Promise Integration (JSPI) API has a new API available in Chrome release M126. The new API eliminates the use of Suspender objects and provides specific functions and constructors for JSPI wrappers. It also introduces the restriction of using WebAssembly functions and suspends calls only when the JavaScript function returns a Promise. Emscripten users can adopt the new API without code changes, while custom integrations become simpler. The old API will be available until Chrome release M128 and Emscripten version 3.1.61 no longer supports it.
