Release 0.70.1 on 2/1/2010

Changes made since 0.70:

* Fixed issue 205: if no keys passed to getAll() were in partitions
  undergoing rebalancing, proxyGetAll() would be called with an
  empty list even if rebalancing wasn't happening

Release 0.70 on 1/27/2010

Changes made since 0.60.1:

* A beta of rebalancing (dynamic cluster expansion) support merged
  into the main branch. See the project's wiki for more information:
  http://wiki.github.com/voldemort/voldemort/voldemort-rebalancing
* New failure detector merged into the main branch:
  http://wiki.github.com/voldemort/voldemort/failure-detection
* Beta mechanism for restoring all of node's data from replicas on
  demand. This is an alternative to a more gradual mechanism provided
  by read-repair: useful when a machine is down for a prolonged period
  and is then re-inserted into the cluster.
  Invoked via JMX: the operation is restoreDataFromReplication in the
  voldemort.server.VoldemortServer MBean, with a mandatory parameter
  (integer >= 1) indicating the number of transfers to do in parallel.
* Simple gossip protocol (for cluster metadata) merged
  into the main branch. Disabled by default: use "enable.gossip=true"
  to enable, use "gossip.interval.ms" to set an interval at which gossip
  occurs (default: 30000 i.e., 30 seconds).
* Fixed issue 190: add a way of aggregating performance data over
  all stores
* Fixed issue 181: stack trackes shouldn't be filled for Obsolete
  version exception

Release 0.60.1 on 12/18/2009

Minor changes made since 0.60:

  archives, fixing an error in the stores.xml for single_node_cluster
  sample config

Release 0.60 on 12/15/2009

Changes made since 0.57.1:

  of entries between nodes, deleting entries on remote nodes,
  remotely deleting and updating metadata
* EC2 testing: a way to periodically run integration and performance
  tests which involve Voldemort instances on different machines
* Experimental support for views
* Interpolation search for read-only stores
* Support for large lists and strings in the JSON serializer
* LZF compression support
* Ruby client contributed
* Fixed issue 170: hanging if a port is used by another process
* Fixed issue 122: suspicious integer division in
  RequestCounter.getThroughput
* Miscellaneous improvements and bug fixes for read-only stores
* Fixed issue 168: added StorageEngine.keys()
