We have a more complete post coming soon, but the short version is that the Mark II ships with the “retail” version of the software. This version does not have certain features that we found problematic to get right for the non-technical user.
Rest assured, we will soon be releasing images that allow you make use of the hardware with any version of Mycroft. This should be within days, not months.
We are also working on making the documentation more clear, for all the versions.
