+To enable wide-scale community testing of the upcoming Spark 4.1.0 release, the Apache Spark community has posted a
+<a href="https://dist.apache.org/repos/dist/release/spark/spark-4.1.0-preview4">Spark 4.1.0-preview4 release</a>.
+This preview is not a stable release in terms of either API or functionality, but it is meant to give the community early
+access to try the code that will become Spark 4.1.0. If you would like to test the release,
+please <a href="https://dist.apache.org/repos/dist/release/spark/spark-4.1.0-preview4">download</a> it, and send feedback using either
+<a href="https://spark.apache.org/community.html">mailing lists</a> or
+<a href="https://issues.apache.org/jira/browse/SPARK/?selectedTab=com.atlassian.jira.jira-projects-plugin:summary-panel">JIRA</a>.
+The documentation is available at the <a href="https://spark.apache.org/docs/4.1.0-preview4/">link</a>.
+
+We'd like to thank our contributors and users for their contributions and early feedback to this release. This release would not have been possible without you.

+
+
+<p>To enable wide-scale community testing of the upcoming Spark 4.1.0 release, the Apache Spark community has posted a
+<a href="https://dist.apache.org/repos/dist/release/spark/spark-4.1.0-preview4">Spark 4.1.0-preview4 release</a>.
+This preview is not a stable release in terms of either API or functionality, but it is meant to give the community early
+access to try the code that will become Spark 4.1.0. If you would like to test the release,
+please <a href="https://dist.apache.org/repos/dist/release/spark/spark-4.1.0-preview4">download</a> it, and send feedback using either
+<a href="https://spark.apache.org/community.html">mailing lists</a> or
+<a href="https://issues.apache.org/jira/browse/SPARK/?selectedTab=com.atlassian.jira.jira-projects-plugin:summary-panel">JIRA</a>.
+The documentation is available at the <a href="https://spark.apache.org/docs/4.1.0-preview4/">link</a>.</p>
+
+<p>We&#8217;d like to thank our contributors and users for their contributions and early feedback to this release. This release would not have been possible without you.</p>
