This PR renames the WebAssembly target triple from
wasm32-unknown-wasitowasm32-unknown-wasip1to align with the broader WebAssembly ecosystem's naming conventions.Motivation
The WebAssembly ecosystem has been migrating from the generic wasi target name to more explicit version-specific names like wasip1 and wasip2. This change has been adopted across multiple toolchains and language ecosystems:
wasm32-wasitarget towasm32-wasi-preview1rust-lang/compiler-team#607)The "p1" suffix explicitly indicates WASI Preview 1, which helps distinguish it from the newer WASI Preview 2 (wasip2) and provides clarity about which version of the WASI specification is being targeted.
Also we already use
wasm32-unknown-wasip1for Embedded WASI target, and having different names for Embedded and non-Embedded is confusing users.Compatibility
Since this is a breaking change to the target name, users will need to update their build configurations. However, the underlying functionality remains identical; only the target identifier changes. Given that we still don't have a stable release for the SDK, I believe it's not too late to migrate.
