    Release 2015.1
    
    This is the first real feature release in two years.  In the
    intervening time, there has been a *lot* of interest in Linux
    containers.  However, there is to my knowledge still not another
    project that achieves the same targeted feature set linux-user-chroot
    has around *non-root* containers.
    
    There are two new *opt-in* restrictions:
    
     - `--mount-devapi /dev`: Create just the API mount points
     - `--seccomp-profile-version 0`: Initial seccomp filtering
    
    This release also drops support for RHEL6 era systems, and seccomp
    is a hard requirement.
