I see threads are going up to Phase 3 - Implementation Phase (where GC already is): [proposals/README.md at d2f6ce711249d37fc21a8933de1f7903cb521302 · WebAssembly/proposals · GitHub](https://github.com/WebAssembly/proposals/blob/d2f6ce711249d37fc21a8933de1f7903cb521302/README.md)

It’s ~~not done~~ but both would help Julia. Julia can already run in WebAssemly with its own GC. Do you see anything there important for Julia, or good to have such as GC, not needing to provide your own. I guess couldn’t provide threads even if it wanted (except for green threading).

[https://webassembly.org/roadmap/](https://webassembly.org/roadmap/)

I actually that some of the “In-progress proposals” are actually already done (just not part of the standard yet), e.g. “[Threads and atomics](https://github.com/WebAssembly/threads/blob/master/proposals/threads/Overview.md)”, I suppose the same thing (and [Exception handling](https://github.com/WebAssembly/exception-handling/blob/master/proposals/exception-handling/Exceptions.md)) in the major web browsers: [Roadmap - WebAssembly](https://webassembly.org/roadmap/)

Anything important going on for Julia with WebAssembly, as is, i.e. not needed any changes?
