Bearing in mind our distro support policy, we need to continue to
support 3.0 series of capstone for a while yet based on what I
see in various distros. eg Ubuntu 18.04 LTS has 3.0.4, as does
Fedora 29.  Version 4.0 is only in a few very new distros:

   https://repology.org/project/capstone/versions

We can of course use features from newer capstone, *provided* we correctly
do conditional compilation so that we can still build against 3.0 series
on distros that have that version.

Regards,
Daniel
