CHANGELOG.md

+## 0.8.5 (January 9, 2017)
+
+#### :bug: Bug Fix
+* `create-react-app`, `react-scripts`
+  * [#1365](https://github.com/facebookincubator/create-react-app/pull/1365) Use yarnpkg alias to run Yarn. ([@fson](https://github.com/fson))
+
+    Fixes an issue where running `create-react-app` failed on systems with Apache Hadoop installed because it falsely detected Hadoop YARN executable as Yarn package manager.
