The new version 0.2.3 has been released today.
This version fixes a problem when loading the website.
At the backend site some more things happened. The project’s code now is much more modular, which should ease further developments by far (because testing should be easier).
Further some libraries have been updated (e.g. RequireJS) and other code changes were made. The backend now requires at least Java7 and is not compatible to Java1.6 anymore.
