+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
- initial release of the hbal, a cluster rebalancing tool
- input data format changed due to hbal requirements
-Previous version was initial announcement.
+Version 0.0.2 (Tue, 06 Jan 2009):
+ - fix handling of some common cases (cluster N+1 compliant from the
+ start, too big depth given, failure to compute solution)
+ - add option to print the needed command list for reaching the
+ proposed solution
+
+Version 0.0.1 (Tue, 06 Jan 2009):
+ - initial release of hn1 tool
