- <title> 8 June, 2007: release 0.13.0 available </title>
- <p>
- In addition to new features, this release contains significant
performance and reliability improvements.
- For example, MapReduce sort performance on large clusters has <a

- </p>
- <note>
- When upgrading an existing <acronym title="Hadoop Distributed File
System">HDFS</acronym> filesystem to this release, you should first start HDFS
with <code>bin/start-dfs.sh -upgrade</code>
- which makes it possible to revert the upgrade. For more information on
this issue, see <a

+ <ul>
+ <li>Better checksums in HDFS. Checksums are no longer
+ stored in parallel HDFS files, but are stored directly by
+ datanodes alongside blocks. This is more efficient for the
+ namenode and also improves data integrity.</li>

- <title> 6 February, 2006: nightly builds </title>
+ <title>25 July, 2007: release 0.13.1 available</title>
