This project adheres to Semantic Versioning.

Possible sections are:

  • Added for new features.
  • Changed for changes in existing functionality.
  • Deprecated for soon-to-be removed features.
  • Removed for now removed features.
  • Fixed for any bug fixes.
  • Security in case of vulnerabilities.

[Unreleased] - ReleaseDate

Added

  • h3o::geom::Solvent to compute the shape of a set of H3 cells.
    • opt-in duplicate detection
    • can works with heterogeneous set of cells

Changed

  • CellIndex::compact now works in-place instead of using iterators.

Removed

  • h3o::geom::dissolve is removed.
    • you can use SolventBuilder::new().build().dissolve(cells) instead.

[0.7.1] - 2024-12-24

Fixed

  • Fix a bug in the Tiler when dealing with transmeridian cells.

[0.7.0] - 2024-11-15

Added

  • h3o::geom::Plotter to compute the cells along lines.
  • h3o::geom::Tiler to compute the cell coverage of plane figures.

Changed

  • small performance enhancement for aarch64, should not affect other platforms
  • error types now derive Error, even in no-std mode.

Removed

  • remove the geometry types wrapper (you can now use geo types directly).
  • remove the ToCells trait, now you can use:
    • h3o::LatLng for Point & MultiPoint.
    • h3o::geom::Plotter for Line, LineString and MultiLineString.
    • h3o::geom::Tiler for Polygon, MultiPolygon, Rect and Triangle.
  • Geometry and GeometryCollection are not directly supported
  • remove the support for geoJSON.
  • remove the ToGeo trait, now you can use:
    • From trait for CellIndex, DirectedEdgeIndex and VertexIndex geom::dissolve` for a set of cell indexes.

[0.6.4] - 2024-05-10

Fixed

  • fix to_geom when dealing with shapes crossing the prime meridian.

[0.6.3] - 2024-05-09

Fixed

  • fix to_cells when dealing with transmeridian cells

[0.6.2] - 2024-03-31

Changed

  • bump dependencies

[0.6.1] - 2024-03-25

Fixed

  • fix a bug in the antimeridian heuristic of to_cells

[0.6.0] - 2024-02-23

Removed

  • remove public constants VERSION_MAJOR, VERSION_MINOR and VERSION_PATCH

[0.5.2] - 2024-02-22

Added

  • add no_std support (std is still enabled by default though)
  • add typed_floats support (disabled by default)

[0.5.1] - 2024-01-27

Fixed

  • fix to_cells when dealing with transmeridian cells

[0.5.0] - 2024-01-15

Added

  • new containment mode, Covers, to handle small geometries within a cell.
  • clarification on the IntersectsBoundary mode.

Removed

  • LocalIJ::anchor, LocalIJ::i and LocalIJ::j no longer exists (fields are public now).

Changed

  • CoordIJ is now public
  • LocalIJ::new_unchecked is replaced by LocalIJ::new

[0.4.0] - 2023-08-09

Changed

  • to_cells and max_cells_count now takes a PolyfillConfig as input.
  • from_radians constructors for geometry now take ownership of the input.

[0.3.5] - 2023-08-05

Fixed

  • update precomputed average edge lengths (they were underestimated).
  • HUGE improvements, both in term of speed and memory usage, for Polygon::to_cells.
  • HUGE improvements, in term of memory usage, for to_geom on cells.

[0.3.4] - 2023-07-28

Fixed

  • fix Point to LatLng conversion

[0.3.3] - 2023-07-21

Fixed

  • compilation issue on Rust 1.71+ due to an outdated version of geo

[0.3.2] - 2023-05-30

Fixed

  • fix the to_geom implementation

Added

  • CellIndex::succ
