+2.1
+ * add listsnapshots command to nodetool (CASSANDRA-5742)
+ * Introduce AtomicBTreeColumns (CASSANDRA-6271)
+ * Multithreaded commitlog (CASSANDRA-3578)

+ to use less memory (CASSANDRA-5519)
+ * Removed multithreaded compaction (CASSANDRA-6142)
+ * Parallelize fetching rows for low-cardinality indexes (CASSANDRA-1337)
+ * change logging from log4j to logback (CASSANDRA-5883)
+ * switch to LZ4 compression for internode communication (CASSANDRA-5887)
+ * Stop using Thrift-generated Index* classes internally (CASSANDRA-5971)
+ * Remove 1.2 network compatibility code (CASSANDRA-5960)
+ * Remove leveled json manifest migration code (CASSANDRA-5996)
+ * Remove CFDefinition (CASSANDRA-6253)
