Today, the Melange team is excited to introduce Melange 2.0. This iteration brings an upgrade to the OCaml 5.1 type checker, along with increased compatibility with the OCaml Platform. Melange 2.0 unifies the compiler attributes and libraries under the Melange brand and it improves developer experience across the ecosystem. We’re also publishing a few battle-tested libraries to OPAM.
Everything we have included in this release has been designed to enhance your experience writing Reason / OCaml for modern JS workflows. Here's a comprehensive look at what's new.
OCaml 5.1 has just been released. Melange 2.0 has been upgraded to use the newly released OCaml 5.1 type checker and compiler libs. As the OCaml community starts to upgrade to the newest version of OCaml, Melange will be co-installable in your OPAM switch.
While the Melange type checker has been upgraded to the 5.x release line, Melange doesn’t yet include support for effect handlers and some of the multicore OCaml primitives. Stay tuned for future updates on this.
