I haven't really been following WASM development in the last year and didn't realize that WASM had moved to a versioned release model. I've been aware of the various features in development[1] and had thought many of the newer features were going to remain optional but I guess now that implementations are expected to support all the features to be able to claim compatibility with e.g. "WASM 3.0"?
It'll be interesting to see what the second non-browser-based WASM runtime to fully support 3.0 will be (I'm guessing wasmtime will be first; I'm not counting Deno since it builds on v8). Garbage collection seems like a pretty tricky feature in particular.
Does anyone know how this 3.0 release fits into the previously announced "evergreen" release model?[2]
> With the advent of 2.0, the Working Group is switching to a so-called “evergreen” model for future releases. That means that the Candidate Recommendation will be updated in place when we create new versions of the language, without ever technically moving it to the final Recommendation state. For all intents and purposes, the latest Candidate Recommendation Draft[3] is considered to be the current standard, representing the consensus of the Community Group and Working Group.
