Upgrading
---------
- Avro record classes used in map/reduce and Hadoop streaming code have
- moved from org.apache.cassandra.avro to org.apache.cassandra.hadoop.avro,
- applications using these classes will need to be updated accordingly.
+ - Upgrading from version 0.7.1 or later can be done with a rolling
+ restart, one node at a time. You do not need to bring down the
+ whole cluster.

+ - The loadbalance command has been removed from nodetool. For similar
+ behavior, decommission then rebootstrap with empty initial_token.
+ - repair now works on a token range, rather than the entire ring. This
+ means that "run repair against each node" will now repair the ring with
+ no redundant work.

+Features
+--------
+ - added CQL client API and JDBC/DBAPI2-compliant drivers for Java and
+ Python, respectively (see: drivers/ subdirectory and doc/cql)
+ - added distributed Counters feature;
+ see http://wiki.apache.org/cassandra/Counters
+ - optional intranode encryption; see comments around 'encryption_options'
+ in cassandra.yaml
+ - compaction multithreading and rate-limiting; see
+ 'compaction_multithreading' and 'compaction_throughput_mb_per_sec' in
+ cassandra.yaml
