Hello Lecoq,

A new set of images will be released soon resolving the current
compatibility version number difference, the pace of development on master
has a small offset for the moment. For now here is the most recent commit
which has compat 17 for both host and images.
https://github.com/EttusResearch/uhd/commit/b17b440d75a874b404f5493cc8ca9a1d6dbeb08c

Please let us know if you have any problems with this version.

Regards,
Derek
