We appreciate the confusion you describe.
The root of this lies in our release schedule in which we make a distinction between stable and latest versions. As a rule we keep most of the content in our site in-sync with the stable version, but we do tend to make exceptions to this rule when we include significant changes to the platform which we want to expose as soon as possible - the change to our mobile implementation included as of version 2.0.5 is one such exception.
Until we release an updated stable version, you can update your studio to the latest version (currently 2.0.8) by following the instructions here .
