 - Altered `EuiHeader`'s location of `EuiHeaderBreadcrumbs` based on the new `truncate` ability ([#1346](https://github.com/elastic/eui/pull/1346))
 - Added support for `href` and `target` props in `EuiBasicTable` actions ([#1347](https://github.com/elastic/eui/pull/1347))
 
+**Bug fixes**
+
+- Fixed EUI when used in an environment lacking ES Modules support, e.g. Jest ([#1358](https://github.com/elastic/eui/pull/1358))
+
 ## [`5.4.0`](https://github.com/elastic/eui/tree/v5.4.0)
 
+**Note: this release broke usage of EUI in non-ES Module compatible environments. This is fixed in `5.5.0`.**
+
 - Added 3 new icons — `folderOpen`, `folderClosed`, and `crosshairs` ([#1350](https://github.com/elastic/eui/pull/1350))
 - Added `bottomGraphic` prop to `EuiCard` for Kibana home page ([#1338](https://github.com/elastic/eui/pull/1338))
 - Added keyboard and screenreader support to `EuiDatePicker` ([#1337](https://github.com/elastic/eui/pull/1337))
