+Version 2.9.0 rc2
+-----------------
+
+*(unreleased)*
+
+Incompatible/important changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- hroller now also plans for capacity to move non-redundant instances off
+ any node to be rebooted; the old behavior of completely ignoring any
+ non-redundant instances can be restored by adding the --ignore-non-redundant
+ option.
+- The cluster option '--no-lvm-storage' was removed in favor of the new option
+ '--enabled-disk-templates'.
+- On instance creation, disk templates no longer need to be specified
+ with '-t'. The default disk template will be taken from the list of
+ enabled disk templates.
+- The monitoring daemon is now running as root, in order to be able to collect
+ information only available to root (such as the state of Xen instances).
+- The ConfD client is now IPv6 compatible.
+- File and shared file storage is no longer dis/enabled at configure time,
+ but using the option '--enabled-disk-templates' at cluster initialization and
+ modification.
+- The default directories for file and shared file storage are not anymore
+ specified at configure time, but taken from the cluster's configuration.
+ They can be set at cluster initialization and modification with
+ '--file-storage-dir' and '--shared-file-storage-dir'.
+- Cluster verification now includes stricter checks regarding the
+ default file and shared file storage directories. It now checks that
+ the directories are explicitely allowed in the 'file-storage-paths' file and
+ that the directories exist on all nodes.
+- The list of allowed disk templates in the instance policy and the list
+ of cluster-wide enabled disk templates is now checked for consistency
+ on cluster or group modification. On cluster initialization, the ipolicy
+ disk templates are ensured to be a subset of the cluster-wide enabled
+ disk templates.
+
+New features
+~~~~~~~~~~~~
+
+- DRBD 8.4 support. Depending on the installed DRBD version, Ganeti now uses
+ the correct command syntax. It is possible to use different DRBD versions
+ on different nodes as long as they are compatible to each other. This
+ enables rolling upgrades of DRBD with no downtime. As permanent operation
+ of different DRBD versions within a node group is discouraged,
+ ``gnt-cluster verify`` will emit a warning if it detects such a situation.
+- New "inst-status-xen" data collector for the monitoring daemon, providing
+ information about the state of the xen instances on the nodes.
+- New "lv" data collector for the monitoring daemon, collecting data about the
+ logical volumes on the nodes, and pairing them with the name of the instances
+ they belong to.
+- New "diskstats" data collector, collecting the data from /proc/diskstats and
+ presenting them over the monitoring daemon interface.
+- The ConfD client is now IPv6 compatible.
+
+New dependencies
+~~~~~~~~~~~~~~~~
+The following new dependencies have been added.
+
+Python
+
+- ``python-mock`` (http://www.voidspace.org.uk/python/mock/) is now a required
+ for the unit tests (and only used for testing).
+
+Haskell
+
+- ``hslogger`` (http://software.complete.org/hslogger) is now always
+ required, even if confd is not enabled.
+
+Since 2.9.0 rc1
+~~~~~~~~~~~~~~~
+
+- Fix bug in cfgupgrade that led to failure when upgrading from 2.8 with
+ at least one DRBD instance.
+
+
+Version 2.9.0 rc1
+-----------------
+
+*(Released Tue, 1 Oct 2013)*
+
+The first release candidate in the 2.9 series. Since 2.9.0 beta1:
+
+- various bug fixes
+- update of the documentation, in particular installation instructions
+- merging of LD_* constants into DT_* constants
+- python style changes to be compatible with newer versions of pylint
+
+
+Version 2.9.0 beta1
+-------------------
+
+*(Released Thu, 29 Aug 2013)*
+
+This was the first beta release of the 2.9 series. All important changes
+are listed in the latest 2.9 entry.
+
+
+Version 2.8.0
+-------------
+
+*(Released Mon, 30 Sep 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.
+- confd now only answers static configuration request over the network. luxid
+ was extracted, listens on the local LUXI socket and responds to live queries.
+ This allows finer grained permissions if using separate users.
+
+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.
+- Add the ``vnet_hdr`` HV parameter for KVM, to control whether the tap
+ devices for KVM virtio-net interfaces will get created with VNET_HDR
+ (IFF_VNET_HDR) support. If set to false, it disables offloading on the
+ virtio-net interfaces, which prevents host kernel tainting and log
+ flooding, when dealing with broken or malicious virtio-net drivers.
+ It's set to true by default.
+- Instance failover now supports a ``--cleanup`` parameter for fixing previous
+ failures.
+- Support 'viridian' parameter in Xen HVM
+- Support DSA SSH keys in bootstrap
+- To simplify the work of packaging frameworks that want to add the needed users
+ and groups in a split-user setup themselves, at build time three files in
+ ``doc/users`` will be generated. The ``groups`` files contains, one per line,
+ the groups to be generated, the ``users`` file contains, one per line, the
+ users to be generated, optionally followed by their primary group, where
+ important. The ``groupmemberships`` file contains, one per line, additional
+ user-group membership relations that need to be established. The syntax of
+ these files will remain stable in all future versions.
+
+
+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).
+
+Since 2.8.0 rc3
+~~~~~~~~~~~~~~~
+- Perform proper cleanup on termination of Haskell daemons
+- Fix corner-case in handling of remaining retry time
+
+
+Version 2.8.0 rc3
+-----------------
+
+*(Released Tue, 17 Sep 2013)*
+
+- To simplify the work of packaging frameworks that want to add the needed users
+ and groups in a split-user setup themselves, at build time three files in
+ ``doc/users`` will be generated. The ``groups`` files contains, one per line,
+ the groups to be generated, the ``users`` file contains, one per line, the
+ users to be generated, optionally followed by their primary group, where
+ important. The ``groupmemberships`` file contains, one per line, additional
+ user-group membership relations that need to be established. The syntax of
+ these files will remain stable in all future versions.
