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

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

## Versioning
The H3 core library adheres to [Semantic Versioning](http://semver.org/).
H3-pg has a `major.minor.patch` version scheme. The major and minor version
numbers of H3-pg are the major and minor version of the bound core library,
respectively. The patch version is incremented independently of the core
library.

Because H3-pg is versioned in lockstep with the H3 core library, please
avoid adding features or APIs which do not map onto the
[H3 core API](https://uber.github.io/h3/#/documentation/api-reference/).

## [3.5.0] - 2019-08-01
### Added
- `h3_get_faces` function to find icosahedron faces for an index.
- `h3_hex_area` replacing `h3_hex_area_m2` and `h3_hex_area_km2`.
- `h3_edge_length` replacing `h3_edge_length_m` and `h3_edge_length_km`.
- Check bindings against `binding-functions` exported by H3.
### Changed
- Bump `h3` to `3.5.0`.
### Fixed
- Fix build for PostgreSQL 12 (#4, thanks @Komzpa)
### Removed
- Removed H3 core library version check, since we know which version we are linking.
- Removed `h3_hex_area_m2`, `h3_hex_area_km2`, `h3_edge_length_m` and `h3_edge_length_km` in favor of `h3_hex_area` and `h3_edge_length`.
- Removed `hex_range`, `hex_ranges` and `hex_range_distances` to align with `binding-functions`.

### Added
- Added more docker test utilities.
### Fixed
- Fix `abs` warning.

## [3.4.0] - 2019-06-13
### Changed
- Use same versioning scheme as python and java bindings, which is to lock major and minor to h3 core, and incrementing patch independently.
### Fixed

### Removed
- Removed degree/radian conversion helpers, recommend postgres built-in RADIANS/DEGREES instead.

### Changed
- Renamed `h3_basecells` to `h3_get_res_0_indexes`.
- Renamed all functions with double `h3_h3_` prefix to use single `h3_` prefix.
