The new year is here, and so is Cassandra 1.2.0!

Key improvements include:

<ul>
	<li><a href="https://www.datastax.com/dev/blog/virtual-nodes-in-cassandra-1-2">Virtual nodes</a>, which improve the granularity of capacity increases and dramatically improve repair and rebuild times in larger clusters. See also&nbsp;this post&nbsp;on upgrading an existing cluster to vnodes.</li>
	<li><a href="https://www.datastax.com/dev/blog/schema-in-cassandra-1-1">CQL3</a>&nbsp;improvements, notably the addition of&nbsp;<a href="https://www.datastax.com/dev/blog/cql3_collections">collection types</a>,&nbsp;<a href="https://www.datastax.com/dev/blog/the-data-dictionary-in-cassandra-1-2">queryable system information</a>, and a&nbsp;<a href="https://www.datastax.com/dev/blog/binary-protocol">CQL-native protocol</a>.</li>
	<li><a href="https://www.datastax.com/dev/blog/tracing-in-cassandra-1-2">Request tracing</a>&nbsp;is available to both CQL and classic Thrift requests, and can also be&nbsp;<a href="https://www.datastax.com/dev/blog/advanced-request-tracing-in-cassandra-1-2">managed programatically</a>.</li>
	<li><a href="https://www.datastax.com/dev/blog/atomic-batches-in-cassandra-1-2">Atomic batches</a>&nbsp;address the possibility of mid-batch coordinator failure.</li>
	<li>Configurable&nbsp;<a href="https://www.datastax.com/dev/blog/handling-disk-failures-in-cassandra-1-2">policies for disk failure</a></li>
	<li>Last but not least, many&nbsp;<a href="https://www.datastax.com/dev/blog/performance-improvements-in-cassandra-1-2">performance improvements</a>&nbsp;to memory usage, column indexes, compaction, streaming, startup time, and more.</li>
