+Version 0.1.1 ( Mon, 25 May 2009):
+  - Add a new program, “hail”, which is an iallocator plugin and can
+    allocate/relocate instances
+  - Experimental support for non-mirrored instances (hail supports them,
+    hbal should no longer abort when it finds such instances and simply
+    ignore them)
+  - The RAPI port and/or scheme can be overriden now, and even “file://”
+    schemes can be used if the message body has been saved under the
+    appropriate name
+  - Lots of code reorganization, esp. rewritten loading pipeline

+    returned by ganeti) as offline
