+<p>We are now aiming for monthly releases.  There have been many
+      bug fixes and improvements in the past month.  MapReduce and DFS
+      are now fairly reliable on clusters with up to 200 nodes.  See

 <h3 class="h4">6 February, 2006: nightly builds</h3>
 <p>Hadoop now has nightly builds.  This automatically creates a
       <a href="http://cvs.apache.org/dist/lucene/hadoop/nightly/">downloadable version of Hadoop every
       night</a>.  All unit tests must pass, or a message is sent to
       the developers mailing list and no new version is created.  This
       also updates the <a href="docs/api/">javadoc</a>.</p>

 <p>The Hadoop code has now been moved into its own Subversion
       tree, renamed into packages under <span class="codefrag">org.apache.hadoop</span>.
       All unit tests pass, but little else has yet been tested.</p>
