 # Changelog
 
+## v5.1.0
+- This release introduces the **backdrop** option (`true` by default). If set to `false`, the spinner background will remain clickable, without any background color.
+
 ## v5.0.1
 - The `rxjs` `peerDependency` has been relaxed from `~6.3.3` to `^6.3.3` so that no warning is thrown when the `rxjs` version has been bumped at application side.
