Wasm 2.0 Completed

As mentioned in the link, this is somewhat old news – the WebAssembly 2.0 spec was published 9 months ago.

https://webassembly.github.io/spec/versions/core/WebAssembly-2.0.pdf (August 2024)

This announcement seems to be something related to the W3C’s endorsement / adoption of WebAssembly’s active development branch. I’m not sure what value the W3C is adding here – active development continues to happen in https://github.com/webassembly/spec, and if I need to target a specific WebAssembly profile (e.g. for conformance testing) then I want a stable version number instead of an indefinitely-mutating “living standard”.

It would be nice to have something like <picture> for wasm. I can provide a short declarative set of creature/version requirements and corresponding URLs and the browser downloads the best one.

Although I guess since the call is in JavaScript anyways it would be easy enough to just implement this yourself. Is there a good way to query supported wasm features?
