+title: ReasonReact is back (and powered by Melange)
+---
+
+ReasonReact moved to `@rescript/react` after the ReScript announcement. The future of ReasonReact has been uncertain ever since. In the meantime, the Melange team announced the first major release of [Melange](https://anmonteiro.substack.com/p/melange-10-is-here) and took the first steps towards deeper integration with the OCaml ecosystem.
+
+Today, we are happy to announce that ReasonReact is back and will be maintained by the Melange team going forward.
+
+## What's changing?
+
+We released ReasonReact to the [opam repository](https://ocaml.org/p/reason-react/latest). In the Melange docs, we document [how to depend](https://melange.re/v1.0.0/package-management/) on packages in opam.
+
+We updated the documentation to reflect these new changes and we will continue to improve it over time.
+
+## Adopting ReasonReact
+
+To use ReasonReact, you must be using Melange. [Get started here](https://melange.re/v1.0.0/getting-started/).
+
+Next:
+
+- Install the latest version of ReasonReact: `opam install reason-react`
+- In your dune file, add `reason-react` to `libraries` and preprocess with `reactjs-jsx-ppx`:
+
+> (libraries reason-react)
+> (preprocess (pps react-jsx-ppx))
+
+- Replace any previously deprecated modules with their new names: `ReactDOMRe` -> `ReactDOM`, `ReactEventRe` -> `ReactEvent`, `ReasonReact` -> `React`.
+- Remove any usage of `ReasonReactCompat` and `ReasonReactOptimizedCreateClass`. These have long been deprecated, and have been removed in this version.
+
+## Future
+
+We started moving all ReasonReact related packages to Melange and 0.11 and want to make sure the ReasonML community can update the 3rd party libraries to use Melange as well.
+
+Some of them are published in [github.com/melange-community](https://github.com/melange-community/) or [github.com/ahrefs](https://github.com/ahrefs). Examples include [melange-react-dates](https://github.com/ahrefs/melange-react-dates) or [melange-recharts](https://github.com/ahrefs/melange-recharts).
+
+There's lots to do for the next version. We are committed to continue improving ReasonReact and make it a great library for the Melange and ReasonML community. In the future, we expect to make the following changes:
+
+- Track `reacjs-jsx-ppx` in this repository, and rename it to `reason-react-ppx`, a more suitable name
+- Use the [new JSX transform](https://legacy.reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html) from React 17
+- Fix code-generation locations for JSX and props
+- Continue improving the documentation
+
+Feel free to reach out if you have any feedback. You can [open an issue](https://github.com/reasonml/reason-react/issues) in this repository, or join the [ReasonML Discord](https://discord.gg/reasonml).
+
