+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 physical volumes on nodes (``gnt-node
+ physical-volumes``) and to modify them (``gnt-node modify-volume``)
+- 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-volume`` command to repair damanged 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 more unittests
+- Fixed critical bug in ganeti-masterd startup
+- Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
+ reinstalling an instance
+- Converted 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
+- Added option to specify maximum timeout on instance shutdown
+
+
Version 2.0.4
-------------
- Added a cluster parameter that prevents Ganeti from modifying of
/etc/hosts
- Added more node information to RAPI responses
-- Added a “gnt-job watch” command that allows following the ouput of a
+- Added a ``gnt-job watch`` command that allows following the ouput of a
job
- Added a bind-address option to ganeti-rapi
- Added more checks to the configuration verify
automatically
- Converted instance reinstall to multi-instance model
+
Version 2.0.3
-------------
any configuration mismatches for disk sizes
- Added ``gnt-master cluste-failover --no-voting`` to allow master
failover to work on two-node clusters
-- Fixed the ‘--net’ option of ``gnt-backup import``, which was unusable
+- Fixed the ``--net`` option of ``gnt-backup import``, which was
+ unusable
- Fixed detection of OS script errors in ``gnt-backup export``
- Fixed exit code of ``gnt-backup export``
- Fixed a couple of issues in instance listing
- Added display of the disk size in ``gnt-instance info``
- Fixed checking for valid OSes in instance creation
-- Fixed handling of the ‘vcpus’ parameter in instance listing and in
+- Fixed handling of the "vcpus" parameter in instance listing and in
general of invalid parameters
- Fixed http server library, and thus RAPI, to handle invalid
username/password combinations correctly; this means that now they
report unauthorized for queries too, not only for modifications,
allowing earlier detect of configuration problems
-- Added a new ‘role’ node list field, equivalent to the master/master
+- Added a new "role" node list field, equivalent to the master/master
candidate/drained/offline flags combinations
- Fixed cluster modify and changes of candidate pool size
- Fixed cluster verify error messages for wrong files on regular nodes
- Fixed a couple of issues with node demotion from master candidate role
- Fixed node readd issues
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
-- Added a new ‘--no-voting’ option for masterfailover to fix failover on
- two-nodes clusters when the former master node is unreachable
+- Added a new ``--no-voting`` option for masterfailover to fix failover
+ on two-nodes clusters when the former master node is unreachable
- Added instance reinstall over RAPI
