• The new MaskExtension allows layers to show/hide objects by a geofence. For example, a map may filter a list of user locations by the boundaries of a given country, or highlight part of a base map that is inside a user-drawn circle or lasso area.
• The new QuadkeyLayer renders filled and/or stroked polygons, with geometry automatically calculated based on a quadkey (geospatial index).
• TileLayer reduced refinementStrategy: 'no-overlap'.
• TileLayer refinementStrategy now accepts a callback function enabling customer refinement strategies.
• TerrainLayer can now be used with non-geospatial views.
• ColumnLayer adds flatShading prop.
• GlobeView lighting in 3D layers is more consistent.
• GoogleMapsOverlay supports camera tilt and bearing for raster maps.
• MVTLayer now supports pointType: 'text' in binary mode.
• Picking with project3D: true now returns more accurate result in non-geospatial views.
• @deck.gl/carto adds fetchMap, streamlining the display of maps created using CARTO platform.
• @deck.gl/carto support for large tables and Databricks. See CARTO documentation for more details.
