+#### New `@angular/google-maps` package!
+Earlier this year, we changed the name of this repo to "angular/components" to emphasize our goal
+to provide more than Material Design components. The 9.0.0 release includes one of the next new
+features in that regard- a new package that wraps the
+[Google Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/tutorial)
+in an easy-to-use Angular component.
+
+You can see the
+[documentation on GitHub](https://github.com/angular/components/blob/master/src/google-maps/README.md)
+for the time being.

+Big thanks to @mbehrlich for contributing this!
