Changelog

The repo is versioned based on SemVer 2.0 using the tiny-but-mighty MinVer from @adamralph. See here for more information on how it works.

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog.

The Unreleased section name is replaced by the expected version of next release. A stable version's log contains all changes between that version and the previous stable version (can duplicate the prereleases logs).
