<commit_before>dev
 * sstable versioning (CASSANDRA-389)
 * bitmask matching in SliceRange queries (CASSANDRA-764)
 * switched to slf4j logging (CASSANDRA-625)
 * drain method to flush memtables and purge commit log prior to shutdown. 
   (CASSANDRA-880)
 * access levels for authentication/authorization (CASSANDRA-900)
 * add ReadRepairChance to CF definition (CASSANDRA-930)
 * fix heisenbug in system tests, especially common on OS X (CASSANDRA-944)
 * convert to byte[] keys internally and all public APIs (CASSANDRA-767)
 * ability to alter schema definitions on a live cluster (CASSANDRA-44)
 * renamed configuration file to cassandra.xml, and log4j.properties to
   log4j-server.properties, which must now be loaded from
   the classpath (which is how our scripts in bin/ have always done it)
   (CASSANDRA-971)
 * change get_count to require a SlicePredicate. create multi_get_count
   (CASSANDRA-744)
 * re-organized endpointsnitch implementations and added SimpleSnitch
   (CASSANDRA-994)
 * Added preload_row_cache option (CASSANDRA-946)
 * add CRC to commitlog header (CASSANDRA-999)
 * removed multiget thrift method (CASSANDRA-739)
 * removed deprecated batch_insert and get_range_slice methods (CASSANDRA-1065)
 * add truncate thrift method (CASSANDRA-531)
 * http mini-interface using mx4j (CASSANDRA-1068)
 * optimize away copy of sliced row on memtable read path (CASSANDRA-1046)
 * replace constant-size 2GB mmaped segments and special casing for index 
   entries spanning segment boundaries, with SegmentedFile that computes 
   segments that always contain entire entries/rows (CASSANDRA-1117)


0.6.3
 * retry to make streaming connections up to 8 times. (CASSANDRA-1019)
 * fix potential for duplicate rows seen by Hadoop jobs (CASSANDRA-1042)
 * reject describe_ring() calls on invalid keyspaces (CASSANDRA-1111)<commit_msg>update CHANGES<commit_after>dev
