Description of the various changes can be found below: Note The release notes are non-cumulative. If you update e.g. from 0.0.2.0 to 0.0.2.3, it makes sense to read the release notes 0.0.2.1 en 0.0.2.2 as well as the 0.0.2.3. Note Release Notes 0.0.2.0. and older are not always available in English, but since 0.0.2.0 is a fully documented version, this should in our opinion not be a problem
