apt-listbugs (0.1.14) unstable; urgency=medium

    Starting from this version, apt-listbugs stores package pins in
    /etc/apt/preferences.d/apt-listbugs, instead of /etc/apt/preferences ;
    during the upgrade of apt-listbugs to a version >= 0.1.14, all your
    apt-listbugs-managed pins are automatically migrated to the new
    location.
    In case you need to _downgrade_ apt-listbugs from a version >= 0.1.14
    to a version <= 0.1.13, you may migrate all your apt-listbugs-managed
    pins back to the old location by issuing the following commands:

      # cat /etc/apt/preferences.d/apt-listbugs >> /etc/apt/preferences
      # rm -f /etc/apt/preferences.d/apt-listbugs
