+
+## Upgrading
+Make sure you fllow the instructions below for upgrading from `1.x` to `2.x`. In the `2.0.2` release, we had to make a small change to the `optimization` config. If you override this config, please review the [change](https://github.com/ionic-team/ionic-app-scripts/commit/785e044) and update your config accordingly.
+
+### Bug Fixes
+
+* **sass:** fix potential null pointer, though it really should never happen ([427e556](https://github.com/ionic-team/ionic-app-scripts/commit/427e556))
+* **webpack:** don't output deptree.js, this requires a minor tweak to the optimization config if you have it customized ([785e044](https://github.com/ionic-team/ionic-app-scripts/commit/785e044))
+* **webpack:** upgrade to webpack 3.2.0 to fix some bugs within Webpack surrounding the ModuleConcatenationPlugin ([f85ade0](https://github.com/ionic-team/ionic-app-scripts/commit/f85ade0))
