# Changelog
All notable changes to the Mesh API will be documented in this file.

The format is 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).

The versions used in the changelog are _API_ versions, not Mesh versions. Each release entry should include both
the API version, and the Mesh version in which said API has been released.
