+Version 0.1.0 (Tue, 19 May 2009):
+  - Drop compatibility with Ganeti 1.2
+  - Add a new minimum score option (with a very low default), should
+    help with very good clusters (but is still not optimal)
+  - Add a --quiet option to hbal
+  - Add support for reading offline nodes directly from the cluster
+
+Version 0.0.8 (Tue, 21 Apr 2009):
+  - hbal: prevent mismatches in wrong node names being passed to -O, by
+	aborting in this case
+  - add the ability to write the commands (-C) to a script via (-C<file>), so
+	that it can be later executed directly; this has also changed the commands
+	to include the ncessary -f flags to skip confirmations
+  - add checks for extra argument in hbal and hn1, so that unintended errors
+	are catched
+  - raise the accepted “missing” memory limit to 512MB, to cover usual Xen
+	reservations
+
+Version 0.0.7 (Mon, 23 Mar 2009):
+  - added support for offline nodes, which are not used as targets for
+    instance relocation and if they hold instances the hbal algorithm
+    will attempt to relocate these away
+  - added support for offline instances, which now will no longer skew
+    the free memory estimation of nodes; the algorithm will no longer
+    create conditions for N+1 failures when such instances are later
+    started
+  - implemented a complete model of node resources, in order to
+    prevent an unintended re-occurrence of cases like the offline
+    instance were we miscalculate some node resource; this gives warning
+    now in case the node reported free disk or free memory deviates by
+    more than a set amount from the expected value
+  - a new tool *hscan* that can generate the input text-file for the
+    other tools by collection via RAPI
+  - some small changes to the build system to make it more friendly;
+    also included the generated documentation in the source archive
+
 Version 0.0.6 (Mon, 16 Mar 2009):
-  - refactored the hbal algorithm to make it stable in the sense that it
+  - re-factored the hbal algorithm to make it stable in the sense that it
     gives the same solution when restarted from the middle; barring
-    rouding of disk/memory and incomplete reporting from Ganeti (for
+    rounding of disk/memory and incomplete reporting from Ganeti (for
     1.2), it should be now feasible to rely on its output without
     generating moves ad infinitum
   - the hbal algorithm now uses two more variables: the node N+1
