+Incompatible/important changes and bugfixes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
resource's ``ip_check`` parameter changed from ``True`` to ``False``
- to match the underlying LUXI interface
+ to match the underlying LUXI interface.
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use
body parameters, see :doc:`RAPI documentation <rapi>`. The server does
not maintain backwards-compatibility as the underlying operation
changed in an incompatible way. The RAPI client can talk to old
servers, but it needs to be told so as the return value changed.
- When creating file-based instances via RAPI, the ``file_driver``
- parameter no longer defaults to ``loop`` and must be specified
-- The deprecated "bridge" nic parameter is no longer supported. Use
- "link" instead.

+- The deprecated ``bridge`` NIC parameter is no longer supported. Use
+ ``link`` instead.
- Support for the undocumented and deprecated RAPI instance creation
request format version 0 has been dropped. Use version 1, supported
since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
- Pyparsing 1.4.6 or above is required, see :doc:`installation
- documentation <install>`
+ documentation <install>`.
- The "cluster-verify" hooks are now executed per group by the
- OP_CLUSTER_VERIFY_GROUP opcode. This maintains the same behavior if
- you just run "gnt-cluster verify", which generates one op per group.

- The environment as passed to the OS scripts is cleared, and thus no

+- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been
+ deprecated.
+- :doc:`New iallocator modes <design-multi-reloc>` have been added to
+ support operations involving multiple node groups.
+- Offline nodes are ignored when failing over an instance.
+
+New features
+~~~~~~~~~~~~
+
+- The ganeti-htools project has been merged into the ganeti-core source
+ tree and will be built as part of Ganeti (see :doc:`install-quick`).
+- Implemented support for :doc:`shared storage <design-shared-storage>`.
+- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting
+ GPT-style partition tables (requires `parted
+ <http://www.gnu.org/s/parted/>`_).
+- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor.
+- Allowed adding tags on instance creation.
+- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`)
+- Allow instances to be started in a paused state, enabling the user to
+ see the complete console output on boot using the console.
+- Added new hypervisor flag to control default reboot behaviour
+ (``reboot_behavior``).
+- Added support for KVM keymaps (hypervisor parameter ``keymap``).
+- Improved out-of-band management support:
+
+ - Added ``gnt-node health`` command reporting the health status of
+ nodes.
+ - Added ``gnt-node power`` command to manage power status of nodes.
+ - Added command for emergency power-off (EPO), ``gnt-cluster epo``.
+
+- Instance migration can fall back to failover if instance is not
+ running.
+- Filters can be used when listing nodes, instances, groups and locks;
+ see *ganeti(7)* manpage.
+- Added post-execution status as variables to :doc:`hooks <hooks>`
+ environment.
+- Instance tags are exported/imported together with the instance.
+- When given an explicit job ID, ``gnt-job info`` will work for archived
+ jobs.
+- Jobs can define dependencies on other jobs (not yet supported via
+ RAPI or command line, but used by internal commands and usable via
+ LUXI).
+
+ - Lock monitor (``gnt-debug locks``) shows jobs waiting for
+ dependencies.
+
+- Instance failover is now available as a RAPI resource
+ (``/2/instances/[instance_name]/failover``).
+- ``gnt-instance info`` defaults to static information if primary node
+ is offline.
+- Opcodes have a new ``comment`` attribute.
+
+Node group improvements
+~~~~~~~~~~~~~~~~~~~~~~~
+
+- ``gnt-cluster verify`` has been modified to check groups separately,
+ thereby improving performance.
+- Node group support has been added to ``gnt-cluster verify-disks``,
+ which now operates per node group.
+- Watcher has been changed to work better with node groups.
+
+ - One process and state file per node group.
+ - Slow watcher in one group doesn't block other group's watcher.
+
+- Added new command, ``gnt-group evacuate``, to move all instances in a
+ node group to other groups.
+- Added ``gnt-instance change-group`` to move an instance to another
+ node group.
+- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support
+ per-group operations.
+- Node groups can be tagged.
+- Some operations switch from an exclusive to a shared lock as soon as
+ possible.
+- Instance's primary and secondary nodes' groups are now available as
+ query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group``
+ and ``snodes.group.uuid``).
+
+Misc
+~~~~
+
+- Numerous updates to documentation and manpages.
+
+ - :doc:`RAPI <rapi>` documentation now has detailed parameter
+ descriptions.
+
+- A lockset's internal lock is now also visible in lock monitor.
+- Log messages from job queue workers now contain information about the
+ opcode they're processing.
+- ``gnt-instance console`` no longer requires the instance lock.
+- A short delay when waiting for job changes reduces the number of LUXI
+ requests significantly.
+- DRBD metadata volumes are overwritten with zeros during disk creation.
