+    <p>Updates the Checkstyle core to version 8.16.</p>
+    <p>
+        Please note that this version requires
+        <strong>Java 8 as the minimum runtime environment</strong>
+        . This requires
+        you to run Eclipse on a Java 8 JVM in order to use this plugin version.
+    </p>
+    <p>This restriction does not affect the ability to analyze Java 5 or lower level source code.</p>
+    <p>
+        Please read the
+        <a target="_blank" href="http://checkstyle.sourceforge.net/releasenotes.html">Checkstyle
+            release notes
+        </a>
+        for details on recent and potentially breaking changes in Checkstyle.
+        Checkstyle configuration files potentially
+        need to be adapted to this version.
