# Changelog

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

The format is loosely based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres
to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

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-ndarray 0.15.0 - 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](https://github.com/uber/h3/releases/tag/v4.0.0-rc3)
as well as making most functions return `Result<T, Error>` as H3 now returns error codes in most functions of its API.
