We will discuss the evolution underway in WASI from being specified in a C header file, into a standard that can be used across many different languages, and takes advantage of new WebAssembly proposals. Powering this evolution is witx, an interface description language designed to fit into the WebAssembly universe. Bytecode alliance members have built a set of tools which use witx to keep WASI software working as the underlying system interfaces evolve.
