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
* 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
* 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.
Default comparators are provided for UTF8, Bytes, Ascii, Long (i64),
and UUID types.
- removed colon-delimited strings in thrift api in favor of explicit
structs such as ColumnPath, ColumnParent, etc. Also normalized
thrift struct and argument naming.
- Added columnFamily argument to get_key_range.
- Change signature of get_slice to accept starting and ending
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.
- added similar consistency_level parameter to read methods
- column-name-set slice with no names given now returns zero columns
instead of all of them. ("all" can run your server out of memory.
use a range-based slice with a high max column count instead.)

using the newly introduced nodeprobe utility.
* More JMX stats
* Remove magic values from internals (e.g. special key to indicate
when to flush memtables)

* Moved to crash-only design; no more shutdown (just kill the process)

0.3.0 RC3
* Fix potential deadlock under load in TCPConnection.
0.3.0 RC2
* Fix possible data loss when server is stopped after replaying
log but before new inserts force memtable flush.
* Added BUGS file
0.3.0 RC1
* Range queries on keys, including user-defined key collation
* Remove support
* Workarounds for a weird bug in JDK select/register that seems
particularly common on VM environments. Cassandra should deploy
fine on EC2 now
* Much improved infrastructure: the beginnings of a decent test suite
("ant test" for unit tests; "nosetests" for system tests), code
coverage reporting, etc.
* Expanded node status reporting via JMX
* Improved error reporting/logging on both server and client
* Reduced memory footprint in default configuration
* Combined blocking and non-blocking versions of insert APIs
* Added FlushPeriodInMinutes configuration parameter to force
flushing of infrequently-updated ColumnFamilies
