Changelog

All notable changes to this project will be documented in this file.

The format is loosely based on Keep a Changelog, and this project adheres to Semantic Versioning.

After version 0.12 the version numbers from the individual crates are decoupled from each other as releases are now done without github actions and without having to coordinate the release process with the h3ronpy python extension.

h3ron-graph Unreleased

h3ron-graph 0.7.0 - 2023-12-16

Changed

  • Upgrade lz4_flex to 0.11, osmpbfreader to 0.16
  • Upgraded geo to 0.26
  • Upgrade indexmap to 2
  • Upgrade h3ron to 0.18

h3ron-graph 0.6.0 - 2023-01-19

Changed

  • Removed io_gdal feature and GDAL dependency.

h3ron-graph 0.5.0 - 2022-10-25

Changed

  • Upgrade geo from 0.22 to 0.23, gdal from 0.12 to 0.13.

h3ron-graph 0.4.0 - 2022-08-23

This version includes the migration from H3 version 3.x to 4.x. This includes some renaming of functions and structs to stay somewhat consistent with the changes made in H3 as well as making most functions return Result<T, Error> as H3 now returns error codes in most functions of its API.

Added

  • h3ron::io module has been relocated to h3ron_graph:io::serde_util as it is fairly custom and only used there. Requires the io_serde_util feature.

Changed

  • Refactored GetGapBridgedCellNodes trait to NearestGraphNodes
  • Make OSM parsing failable.
  • Make path transformation functions failable.
  • Rename ShortestPathOptions::num_gap_cells_to_graph to max_distance_to_graph.
  • Modify Path to contain the intended origin and destination cells.
  • Upgrade geo dependency to 0.21.
  • Optimize ShortestPath to reduce overheads. This change also lead to the introduction of the GetCellEdges trait.
  • According to the naming-convention used by crates like arrow2 the feature gates have been renamed. use-gdal became io_gdal and osm became io_osm. The osm module has been moved into the io module.
  • Reduced the stack-footprint of the OwnedEDgeValue struct. This allows holding larger graphs in memory.

h3ron-graph 0.3.0 - 2022-01-23

Added

  • added WithinWeightThreshold and WithinWeightThresholdMany traits.
  • add Path::cells().
  • Implemented h3ron::to_geo::ToLineString for LongEdge.
  • Add Path::length_m().

Changed

  • Upgraded gdal from 0.10 to 0.12
  • Re-export algorithm traits from algorithm module.
  • The replacement of CompressedIndexVec with IndexBlock in h3ron required making a few LongEdge failable.
  • Switch to rust edition 2021

h3ron-graph 0.2.0 - 2021-11-06

Changed

  • Simplified GetGapBridgedCellNodes trait
  • Converted Path to an enum and added variant to support paths where origin == destination.
  • Improved ShortestPath to support paths where origin == destination. Also added an unittest.

h3ron-graph 0.1.0 - 2021-11-01

Added

  • Added initial version of this crate.
