• Initial release of glmap: High-Performance GPU Geospatial Mapping for sf and terra in R.
• Added C++17 GLMP (vector) and GLMR (Float32 raster) binary encoders (gl_pack_sf_binary(), gl_pack_raster_binary()) with mapbox/earcut.h polygon hole triangulation.
• Added WebGL2 + MapLibre GL JS rendering engine with instanced SDF point shaders, polygon/line mesh shaders, additive Gaussian kernel heatmaps, 64-bit C++ hexagonal spatial binning (add_hexbin()), and RGBA32F floating-point raster fragment shaders (add_raster()) with 0 ms LUT palette switching, real-time surface-normal hillshading, and multi-band math.
• Added gl_providers, add_provider_tiles(), gl_set_api_key(), and gl_get_api_key() supporting CARTO, OpenFreeMap, OpenStreetMap, Esri, OpenTopoMap, USGS, MapTiler, Stadia, Thunderforest, Jawg, and Mapbox.
• Added full leaflet superuser parity functions (add_circles(), add_rectangles(), add_popups(), add_labels(), add_wms_tiles(), show_group(), hide_group(), clear_group(), fly_to_bounds(), set_max_bounds()).
• Added glmap_proxy(), glmapOutput(), and renderGlmap() with leaflet-compatible Shiny events (_click, _bounds, _zoom, _center, _marker_click, _shape_click, _selected) and crosstalk linked brushing.
• Added optional out-of-core DuckDB / .parquet viewport streaming (add_duckdb()) and C++17 spatial grid/R-tree indexing (gl_spatial_index()).
