• Unlimited bandwidth usage (outbound data transfer) is now included with your ArcGIS Online subscription.
• Uploading tile packages from ArcGIS for Desktop is now also included with your subscription.
• Geocoding costs have been reduced by 50%.
• Routing and GeoEnrichment costs have been reduced by nearly 65%.
• Infographic costs have been reduced by more than 80%.
