Developer Edition 2.11 has two new widgets and numerous improvements to existing widgets. The new Threat Analysis widget targets public safety personnel and first responders. It helps identify safe distances and zones for planning events. The new Visibility widget determines what is visible based on distance, observer’s height, and a field of view. In addition, Directions now allows you to configure barriers from your map layers. Analysis adds three new tools: Find Centroids, Find Point Clusters, and Summarize Center and Dispersion. 3D Search enables you to search feature layers. For more information, see the blog.
