+#### Modified Rules
+
+*   The Java rules [`AccessorClassGeneration'](pmd_rules_java_bestpracices.html#accessorclassgeneration) and
+    [`AccessorMethodGeneration`](pmd_rules_java_bestpracices.html#accessormethodgeneration) (both in category
+    `java-bestpractices`) have been modified to be only valid up until Java 10. Java 11 adds support for
+    [JEP 181: Nest-Based Access Control](http://openjdk.java.net/jeps/181) which avoids the generation of
+    accessor classes / methods altogether.
