-* Added a way to programatically list and stop asynchronous
- operations; sharing a common threadpool between SchedulerService,
- AsyncOperationRunner and GossipService.
-* Gossip protocol merged into the main branch.
+* 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).

- all stores.
