   <div class="entry-content">
     <p>The Apache Kudu team is happy to announce the release of Kudu 1.15.0!</p>

 <p>The new release adds several new features and improvements, including the
 following:</p>

 <!--more-->

 <ul>
   <li>
     <p>Kudu now experimentally supports multi-row transactions. Currently only <code class="language-plaintext highlighter-rouge">INSERT</code> and
 <code class="language-plaintext highlighter-rouge">INSERT_IGNORE</code> operations are supported.
 See <a href="https://github.com/apache/kudu/blob/master/docs/design-docs/transactions.adoc">here</a> for a
 design overview of this feature.</p>
   </li>
   <li>
     <p>Kudu now supports Raft configuration change for Kudu masters and CLI tools for orchestrating
 addition and removal of masters in a Kudu cluster. These tools substantially simplify the process
 of migrating to multiple masters, recovering a dead master and removing masters from a Kudu
 cluster. For detailed steps, see the latest administration documentation. This feature is evolving
 and the steps to add, remove and recover masters may change in the future.
 See <a href="https://issues.apache.org/jira/browse/KUDU-2181">KUDU-2181</a> for details.</p>
   </li>
   <li>
     <p>Kudu now supports table comments directly on Kudu tables which are automatically synchronized
 when the Hive Metastore integration is enabled. These comments can be added at table creation time
 and changed via table alteration.</p>
   </li>
   <li>
     <p>Kudu now experimentally supports per-table size limits based on leader disk space usage or number
 of rows. When generating new authorization tokens, Masters will now consider the size limits and
 strip tokens of <code class="language-plaintext highlighter-rouge">INSERT</code> and <code class="language-plaintext highlighter-rouge">UPDATE</code> privileges if either limit is reached. To enable this
 feature, set the <code class="language-plaintext highlighter-rouge">--enable_table_write_limit</code> master flag; adjust the <code class="language-plaintext highlighter-rouge">--table_disk_size_limit</code>
 and <code class="language-plaintext highlighter-rouge">--table_row_count_limit</code> flags as desired or use the <code class="language-plaintext highlighter-rouge">kudu table set_limit</code> tool to set
 limits per table.</p>
   </li>
   <li>
     <p>It is now possible to change the Kerberos Service Principal Name using the <code class="language-plaintext highlighter-rouge">--principal</code> flag. The
 default SPN is still <code class="language-plaintext highlighter-rouge">kudu/_HOST</code>. Clients connecting to a cluster using a non-default SPN must
 set the <code class="language-plaintext highlighter-rouge">sasl_protocol_name</code> or <code class="language-plaintext highlighter-rouge">saslProtocolName</code> to match the SPN base
 (i.e. “kudu” if the SPN is “kudu/_HOST”) in the client builder or the Kudu CLI.
 See <a href="https://issues.apache.org/jira/browse/KUDU-1884">KUDU-1884</a> for details.</p>
   </li>
   <li>
     <p>Kudu RPC now supports TLSv1.3.  Kudu servers and clients automatically negotiate TLSv1.3 for Kudu
 RPC if OpenSSL (or Java runtime correspondingly) on each side supports TLSv1.3.
 If necessary, use the newly introduced flag <code class="language-plaintext highlighter-rouge">--rpc_tls_ciphersuites</code> to customize TLSv1.3-specific
 cipher suites at the server side.
 See <a href="https://issues.apache.org/jira/browse/KUDU-2871">KUDU-2871</a> for details.</p>
   </li>
 </ul>

 <p>The above is just a list of the highlights, for a more complete list of new
 features, improvements and fixes please refer to the <a href="/releases/1.15.0/docs/release_notes.html">release
 notes</a>.</p>

 <p>The Apache Kudu project only publishes source code releases. To build Kudu
 1.15.0, follow these steps:</p>

 <ul>
   <li>Download the Kudu <a href="/releases/1.15.0">1.15.0 source release</a></li>
   <li>Follow the instructions in the documentation to build Kudu <a href="/releases/1.15.0/docs/installation.html#build_from_source">1.15.0 from
 source</a></li>
 </ul>

 <p>For your convenience, binary JAR files for the Kudu Java client library, Spark
 DataSource, Flume sink, and other Java integrations are published to the ASF
 Maven repository and are <a href="https://search.maven.org/search?q=g:org.apache.kudu%20AND%20v:1.15.0">now
 available</a>.</p>

 <p>The Python client source is also available on
 <a href="https://pypi.org/project/kudu-python/">PyPI</a>.</p>

 <p>Additionally, experimental Docker images are published to
 <a href="https://hub.docker.com/r/apache/kudu">Docker Hub</a>, including for AArch64-based
 architectures (ARM).</p>

	<div class="entry-content">
	<p>The Apache Kudu team is happy to announce the release of Kudu 1.15.0!</p>

	<p>The new release adds several new features and improvements, including the
	following:</p>

	<!--more-->

	<ul>
	<li>
	<p>Kudu now experimentally supports multi-row transactions. Currently only <code class="language-plaintext highlighter-rouge">INSERT</code> and
	<code class="language-plaintext highlighter-rouge">INSERT_IGNORE</code> operations are supported.
	See <a href="https://github.com/apache/kudu/blob/master/docs/design-docs/transactions.adoc">here</a> for a
	design overview of this feature.</p>
	</li>
	<li>
	<p>Kudu now supports Raft configuration change for Kudu masters and CLI tools for orchestrating
	addition and removal of masters in a Kudu cluster. These tools substantially simplify the process
	of migrating to multiple masters, recovering a dead master and removing masters from a Kudu
	cluster. For detailed steps, see the latest administration documentation. This feature is evolving
	and the steps to add, remove and recover masters may change in the future.
	See <a href="https://issues.apache.org/jira/browse/KUDU-2181">KUDU-2181</a> for details.</p>
	</li>
	<li>
	<p>Kudu now supports table comments directly on Kudu tables which are automatically synchronized
	when the Hive Metastore integration is enabled. These comments can be added at table creation time
	and changed via table alteration.</p>
	</li>
	<li>
	<p>Kudu now experimentally supports per-table size limits based on leader disk space usage or number
	of rows. When generating new authorization tokens, Masters will now consider the size limits and
	strip tokens of <code class="language-plaintext highlighter-rouge">INSERT</code> and <code class="language-plaintext highlighter-rouge">UPDATE</code> privileges if either limit is reached. To enable this
	feature, set the <code class="language-plaintext highlighter-rouge">--enable_table_write_limit</code> master flag; adjust the <code class="language-plaintext highlighter-rouge">--table_disk_size_limit</code>
	and <code class="language-plaintext highlighter-rouge">--table_row_count_limit</code> flags as desired or use the <code class="language-plaintext highlighter-rouge">kudu table set_limit</code> tool to set
	limits per table.</p>
	</li>
	<li>
	<p>It is now possible to change the Kerberos Service Principal Name using the <code class="language-plaintext highlighter-rouge">--principal</code> flag. The
	default SPN is still <code class="language-plaintext highlighter-rouge">kudu/_HOST</code>. Clients connecting to a cluster using a non-default SPN must
	set the <code class="language-plaintext highlighter-rouge">sasl_protocol_name</code> or <code class="language-plaintext highlighter-rouge">saslProtocolName</code> to match the SPN base
	(i.e. “kudu” if the SPN is “kudu/_HOST”) in the client builder or the Kudu CLI.
	See <a href="https://issues.apache.org/jira/browse/KUDU-1884">KUDU-1884</a> for details.</p>
	</li>
	<li>
	<p>Kudu RPC now supports TLSv1.3. Kudu servers and clients automatically negotiate TLSv1.3 for Kudu
	RPC if OpenSSL (or Java runtime correspondingly) on each side supports TLSv1.3.
	If necessary, use the newly introduced flag <code class="language-plaintext highlighter-rouge">--rpc_tls_ciphersuites</code> to customize TLSv1.3-specific
	cipher suites at the server side.
	See <a href="https://issues.apache.org/jira/browse/KUDU-2871">KUDU-2871</a> for details.</p>
	</li>
	</ul>

	<p>The above is just a list of the highlights, for a more complete list of new
	features, improvements and fixes please refer to the <a href="/releases/1.15.0/docs/release_notes.html">release
	notes</a>.</p>

	<p>The Apache Kudu project only publishes source code releases. To build Kudu
	1.15.0, follow these steps:</p>

	<ul>
	<li>Download the Kudu <a href="/releases/1.15.0">1.15.0 source release</a></li>
	<li>Follow the instructions in the documentation to build Kudu <a href="/releases/1.15.0/docs/installation.html#build_from_source">1.15.0 from
	source</a></li>
	</ul>

	<p>For your convenience, binary JAR files for the Kudu Java client library, Spark
	DataSource, Flume sink, and other Java integrations are published to the ASF
	Maven repository and are <a href="https://search.maven.org/search?q=g:org.apache.kudu%20AND%20v:1.15.0">now
	available</a>.</p>

	<p>The Python client source is also available on
	<a href="https://pypi.org/project/kudu-python/">PyPI</a>.</p>

	<p>Additionally, experimental Docker images are published to
	<a href="https://hub.docker.com/r/apache/kudu">Docker Hub</a>, including for AArch64-based
	architectures (ARM).</p>
