May 19, 2015 -- Esri has released ArcGIS 10.3.1, bringing new capabilities:

Smart Mapping is an innovative approach for creating maps that is available through ArcGIS Online. You can quickly style the features of your map to create useful and visually stunning maps every time.

3D Web Scenes allow you to view, create, and share 3D web scenes in your browser. Available in ArcGIS for Server and Portal for ArcGIS, you can share these scenes within your own infrastructure, and if you choose to, share them publically.

With the ArcGIS 10.3.1 release, ArcGIS for Server with Portal for ArcGIS can now host web scenes and layers that include multipatch–based 3D models and symbology, such as photo-realistic buildings, trees, and visibility domes.
