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.
