Branch rel/0.2.1 has been opened Friday morning on all Novius OS repositories. In our jargon, 'rel' is between beta and RC. Basically, it means the development is over and we're now running quality checks.
The version 0.2.1 of documentation has also been opened. You can see release notes and the migration guide for more details. The english documentation is not yet complete, but it will be done before the official release. Don't hesitate to send us suggestions or push fixes on Github.
The version 0.2.1 of API documentation has also been opened.
