Status and Roadmap

NOTE: Current state of development is also tracked in GitHub projects.

---

Most importantly: While the initial prototype had some preliminary support for memory management through linking with a C-based runtime and thus strings, arrays and classes, these features are not yet implemented in AssemblyScript NEXT.
