+Version 2.1.0
+-------------
+
+Ganeti 2.1 brings many improvements with it. Major changes:
+
+- Added infrastructure to ease automated disk repairs
+- Added new daemon to export configuration data in a cheaper way than
+ using the remote API
+- Instance NICs can now be routed instead of being associated with a
+ networking bridge
+- Improved job locking logic to reduce impact of jobs acquiring multiple
+ locks waiting for other long-running jobs
+
+Detailed implementation details can be found in the Ganeti 2.1 design
+document.
+
+Details
+~~~~~~~
+
+- Added chroot hypervisor
+- Added more options to xen-hvm hypervisor (``kernel_path`` and
+ ``device_model``)
+- Added more options to xen-pvm hypervisor (``use_bootloader``,
+ ``bootloader_path`` and ``bootloader_args``)
+- Added luxi call to submit multiple jobs in one go
+- Added cluster initialization time option to not modify ``/etc/hosts``
+ file on nodes
+- Added network interface parameters
+- Added dry run mode to some LUs
+- Added RAPI resources:
+
+ - ``/2/instances/[instance_name]/info``
+ - ``/2/instances/[instance_name]/replace-disks``
+ - ``/2/nodes/[node_name]/evacuate``
+ - ``/2/nodes/[node_name]/migrate``
+ - ``/2/nodes/[node_name]/role``
+ - ``/2/nodes/[node_name]/storage``
+ - ``/2/nodes/[node_name]/storage/modify``
+ - ``/2/nodes/[node_name]/storage/repair``
+
+- Added OpCodes to evacuate or migrate all instances on a node
+- Added new command to list storage elements on nodes (``gnt-node
+ list-storage``) and modify them (``gnt-node modify-storage``)
+- Added new ssconf files with master candidate IP address
+ (``ssconf_master_candidates_ips``), node primary IP address
+ (``ssconf_node_primary_ips``) and node secondary IP address
+ (``ssconf_node_secondary_ips``)
+- Added ``ganeti-confd`` and a client library to query the Ganeti
+ configuration via UDP
+- Added ability to run hooks after cluster initialization and before
+ cluster destruction
+- Added automatic mode for disk replace (``gnt-instance replace-disks
+ --auto``)
+- Added ``gnt-instance recreate-disks`` to re-create (empty) disks
+ after catastrophic data-loss
+- Added ``gnt-node repair-storage`` command to repair damaged LVM volume
+ groups
+- Added ``gnt-instance move`` command to move instances
+- Added ``gnt-cluster watcher`` command to control watcher
+- Added ``gnt-node powercycle`` command to powercycle nodes
+- Added new job status field ``lock_status``
+- Added parseable error codes to cluster verification (``gnt-cluster
+ verify --error-codes``) and made output less verbose (use
+ ``--verbose`` to restore previous behaviour)
+- Added UUIDs to the main config entities (cluster, nodes, instances)
+- Added support for OS variants
+- Added support for hashed passwords in the Ganeti remote API users file
+ (``rapi_users``)
+- Added option to specify maximum timeout on instance shutdown
+- Added ``--no-ssh-init`` option to ``gnt-cluster init``
+- Added new helper script to start and stop Ganeti daemons
+ (``daemon-util``), with the intent to reduce the work necessary to
+ adjust Ganeti for non-Debian distributions and to start/stop daemons
+ from one place
+- Added more unittests
+- Fixed critical bug in ganeti-masterd startup
+- Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
+ reinstalling an instance
+- Migrated to Sphinx (http://sphinx.pocoo.org/) for documentation
+- Many documentation updates
+- Distribute hypervisor files on ``gnt-cluster redist-conf``
+- ``gnt-instance reinstall`` can now reinstall multiple instances
+- Updated many command line parameters
+- Introduced new OS API version 15
+- No longer support a default hypervisor
+- Treat virtual LVs as inexistent
+- Improved job locking logic to reduce lock contention
+- Match instance and node names case insensitively
+- Reimplemented bash completion script to be more complete
+- Improved burnin
