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. # imported from the archive
