- A new htool called ``hroller`` helps scheduling parallel shutdown of

  nodes on clusters where all instances are shut down, but without ever

  rebooting both primary and secondary node for an instance at the same

  time.

- Queries not needing locks or RPC access to the node can now be

  performed by the confd daemon, making them independent from jobs, and

  thus faster to execute. This is selectable at configure time.

- The KVM hypervisor has been updated with many new hypervisor

  parameters, including a generic one for passing arbitrary command line

  values. See a complete list in :manpage:`gnt-instance(8)`.

- A new tool, called ``mon-collector``, is the stand-alone executor of

  the data collectors for a monitoring system. As of this version, it

  just includes the DRBD data collector, that can be executed by calling

  ``mon-collector`` using the ``drbd`` parameter. See

  :manpage:`mon-collector(7)`.

- New ``exclusive-storage`` node parameter added. When it's set to true,

  physical disks are assigned in an exclusive fashion to instances, as

  documented in :doc:`Partitioned Ganeti <design-partitioned>`.

  Currently, only instances using the ``plain`` disk template are

  supported.

- New network management functionality to support automatic allocation

  of IP addresses and managing of network parameters. See

  :manpage:`gnt-network(8)` for more details.

- New external storage backend, to allow managing arbitrary storage

  systems external to the cluster. See

  :manpage:`ganeti-extstorage-interface(7)`.
