 - Wrap `EuiHorizontalStep` text instead of truncating it ([#653](https://github.com/elastic/eui/pull/653))
 - Fixed a bug where `EuiSideNavItem` wouldn't pass an `onClick` handler down to `<a>` tags if they also had an `href`. ([#664](https://github.com/elastic/eui/pull/664))
 
+**Bug fixes**
