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.

+ ``$sysconfdir/ganeti/file-storage-paths`` now. ``cfgupgrade`` will

$sysconfdir/ganeti/file-storage-paths`` once the cluster has been
upgraded. The reason for requiring this list of paths now is that
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.

- ``prepare-node-join``, to configure the SSH daemon. Paramiko is no

- 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.
+- A new tool named ``node-cleanup`` has been added. It cleans remains of
+ a cluster from a machine by stopping all daemons, removing
+ certificates and ssconf files. Unless the ``--no-backup`` option is
+ given, copies of the certificates are made.
+- Draining (``gnt-cluster queue drain``) and un-draining the job queue
+ (``gnt-cluster queue undrain``) now affects all nodes in a cluster and
+ the flag is not reset after a master failover.
+- Instance creations now support the use of opportunistic locking,
+ potentially speeding up the (parallel) creation of multiple instances.
+ This feature is currently only available via the :doc:`RAPI
+ <rapi>` interface and when an instance allocator is used. If the
+ ``opportunistic_locking`` parameter is set the opcode will try to
+ acquire as many locks as possible, but will not wait for any locks
+ held by other opcodes. If the not enough resources can be found to
+ allocate the instance, the temporary error code
+ :pyeval:`errors.ECODE_TEMP_NORES` is returned. The operation can be
+ retried thereafter, with or without opportunistic locking.
