propellor (0.3.0) unstable; urgency=medium

  * ipv6to4: Ensure interface is brought up automatically on boot.
  * Enabling unattended upgrades now ensures that cron is installed and
    running to perform them.
  * Properties can be scheduled to only be checked after a given time period.
  * Fix bootstrapping of dependencies.
  * Fix compilation on Debian stable.
  * Include security updates in sources.list for stable and testing.
  * Use ssh connection caching, especially when bootstrapping.
  * Properties now run in a Propellor monad, which provides access to
    attributes of the host.
