-Version 2.6.0 beta1
+Version 2.7.0 beta1

 -------------------
 
 -------------------
 

-*(Released Wed, 23 Mar 2011)*
+*(unreleased)*
+
+- ``gnt-instance batch-create`` has been changed to use the bulk create
+  opcode from Ganeti. This lead to incompatible changes in the format of
+  the JSON file. It's now not a custom dict anymore but a dict
+  compatible with the ``OpInstanceCreate`` opcode.
+- Parent directories for file storage need now to be listed in
+  ``$sysconfdir/ganeti/file-storage-paths``. ``cfgupgrade`` will write
+  the file automatically based on old configuration values, but it can
+  not distribute it across all nodes and the file contents should be
+  verified. Use ``gnt-cluster copyfile
+  $sysconfdir/ganeti/file-storage-paths`` once the cluster has been
+  upgraded. The reason for requiring this list of paths now is that
+  before it would have been possible to inject new paths via RPC,
+  allowing files to be created in arbitrary locations. The RPC protocol
+  is protected using SSL/X.509 certificates, but as a design principle
+  Ganeti does not permit arbitrary paths to be passed.
+- The parsing of the variants file for OSes (see
+  :manpage:`ganeti-os-interface(8)` has been slightly changed: now empty
+  lines and comment lines are ignored for better readability.
+- The ``setup-ssh`` tool added in Ganeti 2.2 has been replaced.
+  ``gnt-node add`` now invokes a new tool on the destination node, named
+  ``prepare-node-join``, to configure the SSH daemon. Paramiko is no
+  longer necessary to configure nodes' SSH daemons via ``gnt-node add``.
+- A new user option, :pyeval:`rapi.RAPI_ACCESS_READ`, has been added
+  for RAPI users. It allows granting permissions to query for
+  information to a specific user without giving
+  :pyeval:`rapi.RAPI_ACCESS_WRITE` permissions.
+
+
+Version 2.6.1
+-------------
+
+*(Released Fri, 12 Oct 2012)*
+
+A small bugfix release. Among the bugs fixed:
+
+- Fixed double use of ``PRIORITY_OPT`` in ``gnt-node migrate``, that
+  made the command unusable.
+- Commands that issue many jobs don't fail anymore just because some jobs
+  take so long that other jobs are archived.
+- Failures during ``gnt-instance reinstall`` are reflected by the exit
+  status.
+- Issue 190 fixed. Check for DRBD in cluster verify is enabled only when
+  DRBD is enabled.
+- When ``always_failover`` is set, ``--allow-failover`` is not required
+  in migrate commands anymore.
+- ``bash_completion`` works even if extglob is disabled.
+- Fixed bug with locks that made failover for RDB-based instances fail.
+- Fixed bug in non-mirrored instance allocation that made Ganeti choose
+  a random node instead of one based on the allocator metric.
+- Support for newer versions of pylint and pep8.
+- Hail doesn't fail anymore when trying to add an instance of type
+  ``file``, ``sharedfile`` or ``rbd``.
+- Added new Makefile target to rebuild the whole distribution, so that
+  all files are included.
+
+
+Version 2.6.0
+-------------
+
+*(Released Fri, 27 Jul 2012)*
+
+
+.. attention:: The ``LUXI`` protocol has been made more consistent
+   regarding its handling of command arguments. This, however, leads to
+   incompatibility issues with previous versions. Please ensure that you
+   restart Ganeti daemons soon after the upgrade, otherwise most
+   ``LUXI`` calls (job submission, setting/resetting the drain flag,
+   pausing/resuming the watcher, cancelling and archiving jobs, querying
+   the cluster configuration) will fail.

+Version 2.6.0 rc4
+-----------------
+
+*(Released Thu, 19 Jul 2012)*
+
+Very few changes from rc4 to the final release, only bugfixes:
+
+- integrated fixes from release 2.5.2 (fix general boot flag for KVM
+  instance, fix CDROM booting for KVM instances)
+- fixed node group modification of node parameters
+- fixed issue in LUClusterVerifyGroup with multi-group clusters
+- fixed generation of bash completion to ensure a stable ordering
+- fixed a few typos
+
+
+Version 2.6.0 rc3
+-----------------
+
+*(Released Fri, 13 Jul 2012)*
+
+Third release candidate for 2.6. The following changes were done from
+rc3 to rc4:
+
+- Fixed ``UpgradeConfig`` w.r.t. to disk parameters on disk objects.
+- Fixed an inconsistency in the LUXI protocol with the provided
+  arguments (NOT backwards compatible)
+- Fixed a bug with node groups ipolicy where ``min`` was greater than
+  the cluster ``std`` value
+- Implemented a new ``gnt-node list-drbd`` call to list DRBD minors for
+  easier instance debugging on nodes (requires ``hconfd`` to work)
+
+
+Version 2.6.0 rc2
+-----------------
+
+*(Released Tue, 03 Jul 2012)*
+
+Second release candidate for 2.6. The following changes were done from
+rc2 to rc3:
+
+- Fixed ``gnt-cluster verify`` regarding ``master-ip-script`` on non
+  master candidates
+- Fixed a RAPI regression on missing beparams/memory
+- Fixed redistribution of files on offline nodes
+- Added possibility to run activate-disks even though secondaries are
+  offline. With this change it relaxes also the strictness on some other
+  commands which use activate disks internally:
+  * ``gnt-instance start|reboot|rename|backup|export``
+- Made it possible to remove safely an instance if its secondaries are
+  offline
+- Made it possible to reinstall even though secondaries are offline
+
+
+Version 2.6.0 rc1
+-----------------
+
+*(Released Mon, 25 Jun 2012)*
+
+First release candidate for 2.6. The following changes were done from
+rc1 to rc2:
+
+- Fixed bugs with disk parameters and ``rbd`` templates as well as
+  ``instance_os_add``
+- Made ``gnt-instance modify`` more consistent regarding new NIC/Disk
+  behaviour. It supports now the modify operation
+- ``hcheck`` implemented to analyze cluster health and possibility of
+  improving health by rebalance
+- ``hbal`` has been improved in dealing with split instances
+
+
+Version 2.6.0 beta2
+-------------------
+
+*(Released Mon, 11 Jun 2012)*
+
+Second beta release of 2.6. The following changes were done from beta2
+to rc1:
+
+- Fixed ``daemon-util`` with non-root user models
+- Fixed creation of plain instances with ``--no-wait-for-sync``
+- Fix wrong iv_names when running ``cfgupgrade``
+- Export more information in RAPI group queries
+- Fixed bug when changing instance network interfaces
+- Extended burnin to do NIC changes
+- query: Added ``<``, ``>``, ``<=``, ``>=`` comparison operators
+- Changed default for DRBD barriers
+- Fixed DRBD error reporting for syncer rate
+- Verify the options on disk parameters
+
+And of course various fixes to documentation and improved unittests and
+QA.
+
+
+Version 2.6.0 beta1
+-------------------
+
+*(Released Wed, 23 May 2012)*
+
+First beta release of 2.6. The following changes were done from beta1 to
+beta2:
+
+- integrated patch for distributions without ``start-stop-daemon``
+- adapted example init.d script to work on Fedora
+- fixed log handling in Haskell daemons
+- adapted checks in the watcher for pycurl linked against libnss
+- add partial support for ``xl`` instead of ``xm`` for Xen
+- fixed a type issue in cluster verification

+  clusters)
+
+Plus integrated fixes from the 2.5 branch:
+
+- fixed ``kvm-ifup`` to use ``/bin/bash``
+- fixed parallel build failures
+- KVM live migration when using a custom keymap
+
+
+Version 2.5.2
+-------------
+
+*(Released Tue, 24 Jul 2012)*
+
+A small bugfix release, with no new features:
+
+- fixed bash-isms in kvm-ifup, for compatibility with systems which use a
+  different default shell (e.g. Debian, Ubuntu)
+- fixed KVM startup and live migration with a custom keymap (fixes Issue
+  243 and Debian bug #650664)
+- fixed compatibility with KVM versions that don't support multiple boot
+  devices (fixes Issue 230 and Debian bug #624256)
+
+Additionally, a few fixes were done to the build system (fixed parallel
+build failures) and to the unittests (fixed race condition in test for
+FileID functions, and the default enable/disable mode for QA test is now
+customisable).
