+Version 2.7.0 beta0
+-------------------
+
+*(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.
