Thomas,

Thank you so much for fixing my problems!

I was curious `make showversion` because make command told me that `-r` is illegal even if giving options same as DPDK and no 
warnings for compiling DPDK's documentation.

By the way, do you use python3 for sphinx-build? I am using python2 and there are no warnings in the second issue while docs 
compilation. If so, I should update to python3 to be the same environment as yours.

I understand pushing tag is also incorrect. I simply added the tag and pushed.
   $ git tag v18.08
   $ git push origin v18.08

Thanks,
