+## 0.1.0 - 2026-05-21
+
+Initial public release.
+
+### Added
+
+- First-order Fast Marching Method solver for 2D eikonal arrival-time fields.
+- Multi-source solving and target early termination.
+- Upwind FMM path backtracing from finalized cells.
+- 8-neighbor weighted graph routing with exact shortest paths for the graph model.
+- Terrain-aware graph routing with 3D surface distance, elevation profiles, ascent/descent statistics, and configurable uphill/downhill factors.
+- Isochrone and isochrone-boundary extraction from distance fields.
+- `CostField` construction from uniform values, obstacle masks, arrays, and slope rasters.
+- Optional `parallel` feature for Rayon-accelerated cost-field construction.
+
+### Notes
+
+- The crate operates on regular `ndarray::Array2` grids and keeps raster I/O, CRS handling, reprojection, and vertical datum handling out of scope.
+- Terrain nodata is represented by non-finite DEM elevations; cost-field barriers use zero-valued cells.
+- Early-terminated solves return incomplete distance fields with unfinished cells reported as `f64::INFINITY`.
