* All non-seed nodes will attempt to bootstrap when started, until
bootstrap successfully completes. -b option is removed.
(CASSANDRA-438)
* Allow multiple simultaneous flushes, improving flush throughput
on multicore systems (CASSANDRA-401)
* Split up locks to improve write and read throughput on multicore systems
(CASSANDRA-444, CASSANDRA-414)
* More efficient use of memory during compaction (CASSANDRA-436)
* autobootstrap option: when enabled, all non-seed nodes will attempt
to bootstrap when started, until bootstrap successfully
completes. -b option is removed. (CASSANDRA-438)
* Unless a token is manually specified in the configuration xml,
a bootstraping node will use a token that gives it half the

* Web client interface added to contrib (CASSANDRA-457)
* More-efficient flush for Random, CollatedOPP partitioners
for normal writes (CASSANDRA-446) and bulk load (CASSANDRA-420)
