AppArmor 2.11.3 is a maintenance release of the user space components
of the AppArmor security project. The kernel portion of the project
is maintained and pushed separately.
This version of the userspace should work with all kernel versions from
2.6.15 and later (some earlier version of the kernel if they have the
apparmor patches applied). And supports features released in the 4.18
kernel and ubuntu 18.04 kernel.
