Wasmer now supports WASI 🎉.
The emscripten implementation has improved vastly, and now Wasmer can run PHP, SQLite and Lua (check them on the examples dir on this repo)
The wasmer CLI now ships with three different backends: Singlepass (fast compilation), Cranelift (default) and LLVM (fast runtime). You can try it with wasmer run --backend=singlepass ...
We also improved the APIs and shipped tons of bug fixes and improvements.
