Changes in version 0.1.7 (2026-05-12) - Updated the CRAN Rust build path to use a dependency graph compatible with rustc/cargo 1.77.2. Changes in version 0.1.0 Initial release. Tile generation - freestile() creates PMTiles archives from sf data frames with zero external dependencies (no tippecanoe, no Java, no Go). - Supports MapLibre Tiles (MLT) and Mapbox Vector Tiles (MVT) output formats. - Multi-layer output via named lists or freestile_layer() per-layer zoom control. Geometry types - POINT, MULTIPOINT, LINESTRING, MULTILINESTRING, POLYGON, MULTIPOLYGON. - Automatic CRS transformation to WGS84. - Z/M dimension handling (dropped automatically). Performance features - Parallel tile encoding with rayon (across tiles and within tiles). - Tile-pixel grid snapping for zoom-adaptive simplification without slivers. - Buffered tile assignment and clipping for seamless tile boundaries. Feature management - drop_rate exponential feature thinning with Morton-curve spatial ordering for points and area-based ordering for polygons/lines. - base_zoom control for ensuring all features present at higher zooms. - cluster_distance point clustering with point_count attribute. - coalesce line merging and polygon grouping. MLT encoder - Spec-compliant MapLibre Tile encoder with varint, delta, RLE, and dictionary encoding. - Validated against mlt-core 0.1.2 reference decoder.
