## Roadmap
The project is not currently production-ready, but you can already run some tests.
The compiler is feature complete for milestone 1. There is a release candidate. Please test it and report bugs if the compiled code has the same behavior as Java.
Also the current browsers (Chrome, Edge, Firefox, Opera, ...) supports the [needed features](https://wasm-feature-detect.surma.technology/).

#### Status of Required WebAssembly Features
The following table shows the status of future WebAssembly features required by JWebAssembly in nightly builds in various implementations. These features are already used by the trunk version of JWebAssembly. If you want know the status of your current browser then look for [your browser support](https://wasm-feature-detect.surma.technology/).

- For SpiderMonkey it based on the nightly build of [jsshell](https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/).
- For WABT it based on [libwabt.js](https://github.com/WebAssembly/wabt/blob/master/demo/libwabt.js) via node module wabt@nightly.
To use it also some flags and switches are currently needed.
