ⓘ This documentation is aimed at users of the component model: developers of libraries and applications. Compiler and Wasm runtime developers can take a look at the Component Model specification to see how to add support for the component model to their project.
Status
WASI 0.2.0 was released Jan 25, 2024, providing a stable release of WASI and the component model. This is a stable set of WIT definitions that components can target. WASI proposals will continue to evolve and new ones will be introduced; however, users of the component model can now pin to the stable 0.2.0 release.
