Cool new features released with ArcGIS JS APIs 4.17, my first take aways:
- View Constraints: now you can limit the user navigation to be around certain geometry, help the user to focus on specific area
- Layer Visibility Animation: the APIs now supports fading effect while toggling layer visibility
- OGC Support: this is emphasized with 2 new features
- WCSLayer: new layer allows rendering raster data from OGC Web Coverage Service
- WMSLayer time enabled: now you can configured widgets like Time Slider with time-enabled WMS layers
- Widgets updates, now Bookmarks widgets saves the bookmark thumbnail, the user will have to set thumbnail URL
