 ## [`master`](https://github.com/elastic/eui/tree/master)
 
+- Added the ability for `EuiBetaBadge` to appear on `EuiPanel` similar to `EuiCard` ([#885](https://github.com/elastic/eui/pull/888))
+
 **Bug fixes**
 - Removed `.nvmrc` file from published npm package ([#892](https://github.com/elastic/eui/pull/892))
 - `EuiComboBox` no longer shows the _clear_ icon when it's a no-op ([#890](https://github.com/elastic/eui/pull/890))
