 ## [Unreleased]
 
+## [6.0.3]
+##### Fixed
+- Added assets symlinking support on Heroku [#446](https://github.com/shakacode/react_on_rails/pull/446) by [Alexey Karasev](https://github.com/alleycat-at-git).
+
 ## [6.0.2]
 ##### Fixed
 - Fix colisions in ids of DOM nodes generated by `react_component` by indexing in using an UUID rather than an auto-increment value. This means that it should be overriden using the `id` parameter of `react_component` if one wants to generate a predictable id (_e.g._ for testing purpose). See [Issue #437](https://github.com/shakacode/react_on_rails/issues/437). Fixed in [#438](https://github.com/shakacode/react_on_rails/pull/438) by [Michael Baudino](https://github.com/michaelbaudino).
