Is MarkerClusterer deprecated? What should I use instead?
<p>I need to implement marker clustering and found a tutorial in the official <a href="https://developers.google.com/maps/documentation/javascript/marker-clustering" rel="nofollow">Google Maps Documentation</a>, but when following the link to the <a href="https://github.com/googlemaps/js-marker-clusterer" rel="nofollow">MarkerClusterer repo</a> it says its no longer maintained and kept for <em>historical purpose only</em>. </p>

<p>Should I use something else, or is this safe to use? </p>
