Hi,
As already announced in January this year [1] these will be the last
releases for the Marionette client and harness, which are getting pushed
to PyPI. Means that from now on you have to build these packages on your
own if you really need bug fixes and features.
Given that the usage of both packages will be faded out also for us
internally, we won't care about backward compatibility from now on.
All the changes which went into those releases can be seen here:

Cheers,
Henrik
