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

Critical bugfixes or breaking changes are marked using a warning symbol: ⚠️

The format is based on Keep a Changelog.

Versioning

The H3 core library adheres to Semantic Versioning. 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.
