+Version 2.8.0 beta1
+-------------------
+
+*(Released Mon, 24 Jun 2013)*
+
+Incompatible/important changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Instance policy can contain multiple instance specs, as described in
+ the “Constrained instance sizes” section of :doc:`Partitioned Ganeti
+ <design-partitioned>`. As a consequence, it's not possible to partially change
+ or override instance specs. Bounding specs (min and max) can be specified as a
+ whole using the new option ``--ipolicy-bounds-specs``, while standard
+ specs use the new option ``--ipolicy-std-specs``.
+- The output of the info command of gnt-cluster, gnt-group, gnt-node,
+ gnt-instance is a valid YAML object.
+- hail now honors network restrictions when allocating nodes. This led to an
+ update of the IAllocator protocol. See the IAllocator documentation for
+ details.
+
+New features
+~~~~~~~~~~~~
+
+- The :doc:`Remote API <rapi>` daemon now supports a command line flag
+ to always require authentication, ``--require-authentication``. It can
+ be specified in ``$sysconfdir/default/ganeti``.
+- A new cluster attribute 'enabled_disk_templates' is introduced. It will
+ be used to manage the disk templates to be used by instances in the cluster.
+ Initially, it will be set to a list that includes plain, drbd, if they were
+ enabled by specifying a volume group name, and file and sharedfile, if those
+ were enabled at configure time. Additionally, it will include all disk
+ templates that are currently used by instances. The order of disk templates
+ will be based on Ganeti's history of supporting them. In the future, the
+ first entry of the list will be used as a default disk template on instance
+ creation.
+- ``cfgupgrade`` now supports a ``--downgrade`` option to bring the
+ configuration back to the previous stable version.
+- Disk templates in group ipolicy can be restored to the default value.
+- Initial support for diskless instances and virtual clusters in QA.
+- More QA and unit tests for instance policies.
+- Every opcode now contains a reason trail (visible through ``gnt-job info``)
+ describing why the opcode itself was executed.
+- The monitoring daemon is now available. It allows users to query the cluster
+ for obtaining information about the status of the system. The daemon is only
+ responsible for providing the information over the network: the actual data
+ gathering is performed by data collectors (currently, only the DRBD status
+ collector is available).
+- In order to help developers work on Ganeti, a new script
+ (``devel/build_chroot``) is provided, for building a chroot that contains all
+ the required development libraries and tools for compiling Ganeti on a Debian
+ Squeeze system.
+- A new tool, ``harep``, for performing self-repair and recreation of instances
+ in Ganeti has been added.
+- Split queries are enabled for tags, network, exports, cluster info, groups,
+ jobs, nodes.
+- New command ``show-ispecs-cmd`` for ``gnt-cluster`` and ``gnt-group``.
+ It prints the command line to set the current policies, to ease
+ changing them.
+
+New dependencies
+~~~~~~~~~~~~~~~~
+The following new dependencies have been added:
+
+For Haskell:
+- The ``curl`` library is not optional anymore for compiling the Haskell code.
+- ``snap-server`` library (if monitoring is enabled).
+
+For Python:
+- The minimum Python version needed to run Ganeti is now 2.6.
+- ``yaml`` library (only for running the QA).
+
