## The dependency [uglify-js](https://github.com/mishoo/UglifyJS2) was updated from `3.5.14` to `3.5.15`.

🚨 [View failing branch](https://github.com/aethant/merino/compare/master...aethant:greenkeeper%2Fuglify-js-3.5.15).

This version is **covered** by your **current version range** and after updating it in your project **the build failed**.

uglify-js is a direct dependency of this project, and **it is very likely causing it to break**. If other packages depend on yours, this update is probably also breaking those in turn.
