   <div class="entry-content">
     <p>The Apache Kudu team is happy to announce the release of Kudu 1.5.0!</p>

 <p>Apache Kudu 1.5.0 is a minor release which offers several new features,
 improvements, optimizations, and bug fixes.</p>

 <p>Highlights include:</p>

 <!--more-->

 <ul>
   <li>optimizations to improve write throughput and failover recovery times</li>
   <li>the Raft consensus implementation has been made more resilient and flexible
 through “tombstoned voting”, which allows Kudu to self-heal in more edge-case
 scenarios</li>
   <li>the number of threads used by Kudu servers has been further reduced, with
 additional reductions planned for the future</li>
   <li>a new configuration dashboard on the web UI which provides a high-level
 summary of important configuration values</li>
   <li>a new <code class="language-plaintext highlighter-rouge">kudu tablet move</code> command which moves a tablet replica from one tablet
 server to another</li>
   <li>a new <code class="language-plaintext highlighter-rouge">kudu local_replica data_size</code> command which summarizes the space usage
 of a local tablet</li>
   <li>all on-disk data is now checksummed by default, which provides error detection
 for improved confidence when running Kudu on unreliable hardware</li>
 </ul>

 <p>The above list of changes is non-exhaustive. Please refer to the
 <a href="/releases/1.5.0/docs/release_notes.html">release notes</a>
 for an expanded list of important improvements, bug fixes, and
 incompatible changes before upgrading.</p>

 <ul>
   <li>Download the <a href="/releases/1.5.0/">Kudu 1.5.0 source release</a></li>
   <li>Convenience binary artifacts for the Java client and various Java
 integrations (eg Spark, Flume) are also now available via the ASF Maven
 repository.</li>
 </ul>
