+        
+          <p>Apache Drill 0.7.0, the third beta release for Drill, is designed to help
+enthusiasts start working and experimenting with Drill. It also continues the
+Drill monthly release cycle as we drive towards general availability.</p>
+
+<p>This release is available as
+<a href="http://www.apache.org/dyn/closer.cgi/drill/drill-0.7.0/apache-%0Adrill-0.7.0.tar.gz">binary</a> and
+<a href="http://www.apache.org/dyn/closer.cgi/drill/drill-0.7.0/apache-%0Adrill-0.7.0-src.tar.gz">source</a> tarballs that are compiled against Apache Hadoop.
+Drill has been tested against MapR, Cloudera, and Hortonworks Hadoop
+distributions. There are associated build profiles and JIRAs that can help you
+run Drill against your preferred distribution</p>
+
+<p>Apache Drill 0.7.0 Key Features</p>
+
+<ul>
+<li><p>No more dependency on UDP/Multicast - Making it possible for Drill to work well in the following scenarios:</p>
+
+<ul>
+<li>UDP multicast not enabled (as in EC2)</li>
+<li>Cluster spans multiple subnets</li>
+<li>Cluster has multihome configuration</li>
+</ul></li>
+<li><p>New functions to natively work with nested data - KVGen and Flatten </p></li>
+<li><p>Support for Hive 0.13 (Hive 0.12 with Drill is not supported any more) </p></li>
+<li><p>Improved performance when querying Hive tables and File system through partition pruning</p></li>
+<li><p>Improved performance for HBase with LIKE operator pushdown</p></li>
+<li><p>Improved memory management</p></li>
+<li><p>Drill web UI monitoring and query profile improvements</p></li>
+<li><p>Ability to parse files without explicit extensions using default storage format specification</p></li>
+<li><p>Fixes for dealing with complex/nested data objects in Parquet/JSON</p></li>
+<li><p>Fast schema return - Improved experience working with BI/query tools by returning metadata quickly</p></li>
+<li><p>Several hang related fixes</p></li>
+<li><p>Parquet writer fixes for handling large datasets</p></li>
+<li><p>Stability improvements in ODBC and JDBC drivers</p></li>
+</ul>
+
+<p>Apache Drill 0.7.0 Key Notes and Limitations</p>
+
+<ul>
+<li>The current release supports in-memory and beyond-memory execution. However, you must disable memory-intensive hash aggregate and hash join operations to leverage this functionality.</li>
+<li>While the Drill execution engine supports dynamic schema changes during the course of a query, some operators have yet to implement support for this behavior, such as Sort. Other operations, such as streaming aggregate, may have partial support that leads to unexpected results.</li>
+</ul>

+          <p>Apache Drill 0.8.0, continues the Drill release cycle as we drive towards general availability.
+This release includes <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&amp;version=12328812">243 resolved JIRAs</a> and numerous enhancements.</p>
+
+<p>This release is available as
+<a href="http://www.apache.org/dyn/closer.cgi/drill/drill-0.8.0/apache-drill-0.8.0.tar.gz">binary</a> and
+<a href="http://www.apache.org/dyn/closer.cgi/drill/drill-0.8.0/apache-drill-0.8.0-src.tar.gz">source</a> tarballs that are compiled against Apache Hadoop.
+Drill has been tested against MapR, Cloudera, and Hortonworks Hadoop
+distributions. There are associated build profiles and JIRAs that can help you
+run Drill against your preferred distribution</p>
+
+<p>Apache Drill 0.8.0 Key Features:</p>
+
+<ul>
+<li><strong>Bytecode rewriting</strong>. Drill now leverages code optimization techniques such as bytecode rewriting and inlining to enhance the speed of many queries by reducing overall memory usage and CPU instructions.</li>
+<li><strong>Advanced partition pruning</strong>. Drill can now prune partitions based on arbitrarily complex expressions. For example, specify WHERE dir0 LIKE &#39;2015-%&#39; and your query will look inside the directory &quot;2015-01&quot; but not inside &quot;2014-12&quot;.</li>
+<li><strong>Real-time query diagnostics</strong>. You can now see exactly what your queries are doing in real-time, making it easy to troubleshoot, optimize and manage execution.</li>
+<li><strong>Large records, large # of files</strong>. Drill was previously limited to small records of up to 128KB. It now supports records of any size. In addition, query performance has been improved when dealing with large numbers of files thanks to a variety of optimizations such as parallel metadata reads.</li>
+<li><strong>More SQL</strong>. Drill now features complete support for UNION ALL and COUNT(DISTINCT). Drill 0.8 also includes new functions such as unix_timestamp and the window functions sum, count and rank. Note that these window functions should be considered beta.</li>
+<li><strong>Better compression</strong>. Drill can now query compressed JSON files. In addition, the user can control Parquet compression in CTAS (CREATE TABLE AS) statements.</li>
+<li><strong>Performance</strong>. Drill 0.8 includes broadcast joins, disk-based joins, parallel metadata reads and many other performance-related enhancements.</li>
