+0.4.0 beta
  * On-disk data format has changed to allow billions of keys/rows per
    node instead of only millions
  * Multi-keyspace support
- * Added option to fsync before acknowledging writes
  * Scan all sstables for all queries to avoid situations where
    different types of operation on the same ColumnFamily could
    disagree on what data was present
  * Snapshot support via JMX
- * BinaryMemtable support for bulk load via hadoop; see
-   contrib/bmt_example for an example of using it.
  * Thrift API has changed a _lot_:
     - removed time-sorted CFs; instead, user-defined comparators
       may be defined on the column names, which are now byte arrays.

       columns as well as an offset.  (This allows use of indexes.)
       Added "ascending" flag to allow reasonably-efficient reverse
       scans as well.  Removed get_slice_by_range as redundant.

     - get_key_range operates on one CF at a time
     - changed `block` boolean on insert methods to ConsistencyLevel enum,
       with options of NONE, ONE, QUORUM, and ALL.
