 #### :boom: Breaking Change
 
 - Remove support for the legacy Reason syntax. Existing Reason code can be converted to ReScript syntax using ReScript 9 as follows:
   - `npm i -g rescript@9`
   - `rescript convert <reason files>`
-- Remove obsolete built-in project templates and the "rescript init" functionality. This will be replaced by the create-rescript-app project that is maintained separately.
+- Remove obsolete built-in project templates and the "rescript init" functionality. This is replaced by [create-rescript-app](https://github.com/rescript-lang/create-rescript-app) which is maintained separately.
+- Do not attempt to build ReScript from source on npm postinstall for platforms without prebuilt binaries anymore.
 - Made pinned dependencies transitive: if *a* is a pinned dependency of *b* and *b* is a pinned dependency of *c*, then *a* is implicitly a pinned dependency of *c*. This change is only breaking if your build process assumes non-transitivity.
 - Curried after uncurried is not fused anymore: `(. x) => y => 3` is not equivalent to `(. x, y) => 3` anymore. It's instead equivalent to `(. x) => { y => 3 }`.
 Also, `(. int) => string => bool` is not equivalen to `(. int, string) => bool` anymore.
