5 May, 2006: release 0.2.0 available
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.
6 February, 2006: nightly builds
Hadoop now has nightly builds. This automatically creates a downloadable version of Hadoop every night. 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 javadoc.
3 February, 2006: Hadoop code moved out of Nutch
The Hadoop code has now been moved into its own Subversion tree, renamed into packages under org.apache.hadoop. All unit tests pass, but little else has yet been tested.
