+Lagom.js moved to Scala.js 1.x starting with version `0.4.0-1.6.2`. Scala.js 0.6 is no longer supported, the last version to support it was `0.3.2-1.6.2 `. For all past releases, see [releases](#Releases).
 
 Lagom.js does not support the Lagom Java API. It only supports the Lagom Scala API because Scala.js only supports Scala.

+## Releases
+
+Lagom.js tracks Lagom and generally doesn't continue development on previous Lagom releases. Since Lagom maintains a stable API within a minor release (e.g., 1.6.x) any version of Lagom.js built for that minor release should work. However, if you need Lagom.js for a specific previous Lagom release the previous Lagom.js releases are listed below. If you have an issue with a previous Lagom.js release please open an [issue](https://github.com/mliarakos/lagom-js/issues) and it will be considered on a case-by-case basis.
