           <p><b>MADlib v0.2.1beta</b> patch release is ready. It includes multiple bug fixes and
           improvements. See <a href="https://github.com/madlib/madlib/blob/v0.2.1beta/ReleaseNotes.txt"
             target="blank">release notes</a> to find out more about the content.

           <p><b>MADlib v0.2beta</b> version is ready for download. For detail information about
             its content please refer to the <a href="https://github.com/madlib/madlib/blob/v0.2beta/ReleaseNotes.txt"
             target="blank"> Release Notes</a> file. Although
             the bulk of the code is standard SQL, some methods use platform-specific
             subroutines to achieve good performance. Initial targets are PostgreSQL and
             Greenplum; ports to other SQL platforms are expected. After beta release,
             we will invite participation from the broader community through a standard
             open-source contribution submission process.
           </p>
           <h2>History</h2>
           <p>MADlib grew out of discussions between database engine developers, data
             scientists, IT architects and academics, who were interested in new
             approaches to scalable, sophisticated in-database analytics. These
             discussions were written up in a paper in VLDB 2009 that coined the phrase
             <a href="http://db.cs.berkeley.edu/papers/vldb09-madskills.pdf" target="blank">
             "MAD Skills"</a> for data analysis. The MADlib software project began the
             following year as a collaboration between researchers at
             <a href="http://db.cs.berkeley.edu/" target="blank">UC Berkeley</a> and
             engineers and data scientists at
             <a href="http://www.greenplum.com/" target="blank">EMC/Greenplum.</a></p>
