Hello everyone, Just a quick mail to let you know that gr-tempest now supports GNU Radio 3.8 too. It was actually much easier than I thought it would be, thanks to the guide at the wiki. I had a little bit of trouble creating both branches (one for 3.7 and master supporting 3.8), but that's my lack of experience on using git (i.e. using it for other than the typical git add, git commit, git push :-) ). best Federico PS Thanks Jared for your comments.
