+Release 0.81 on 6/15/2010
+
+Changes made since 0.80.2:
+
+* IMPORTANT: we have upgraded the Hadoop Core jar to v0.20.2. Since
+ this version of Hadoop requires Java 6, in order to retain backwards
+ compatibility with Java 5, you will need to replace this jar with
+ the Hadoop 0.18.* core jar.
+* Multiple donors for Voldemort Rebalancing: speeds up rebalancing, by
+ allowing a single stealer node to transfer partitions from multiple
+ nodes
+* Features for EC2 Testing
+* Read-only Stores: backwards compatibility with 0.70, bug fix in
+ Checksum code
+* Hadoop InputFormat, Pig LoadFunc in Contrib: ability to perform
+ Map/Reduce (either directly via Hadoop or using Pig) over data in
+ Voldemort stores. See:
+ < contrib/hadoop/test/voldemort/hadoop/VoldemortWordCount.java > for
+ an example.
+* Voldemort Performance Tool: performance measurement tool based on
+ YCSB (Yahoo Cloud Serving Benchmark) code. Run
+ < bin/voldemort-performance-tool.sh --help > for more information.
+* Reverted default failure detector implementation back to
+ BannagedPeriodFailureDetector due to potential bugs in the
+ ThresholdFailureDetector
+
Release 0.80.2 on 4/27/2010
Changes made since 0.80.1:
-* Batched NIO writes

-* Minor bugs in Rebalancing
-* Issue 240: Voldemort fetcher should use different temp directory for different stores

+* Batched NIO writes (improves performance for AdminClient/Streaming
+ operations when the NIO connector is enabled)
+* VoldemortAdminTool: Added support to specify stores, support to
+ fetch all keys to a binary file, support to save keys in ASCII
+ (JSON) format [experimental], capability to add stores. Run
+ < bin/voldemort-admin-tool.sh --help > for more information.
