0.7.4 is now in Debian SID and 0.7.5 has been just released with some minor fixes. Coming soon on Debian SID. (Maybe end of this week, early next week)
0.7.4 add support for 4.14 Kernel which is important when backports update the kernel to 4.14.
I've been following progress. I just uploaded the 0.7.4 versions of all of the zfs and spl packages.
