+A new command ``list-drbd`` has been added to the ``gnt-node`` script to

+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
