 ### New and noteworthy
 
+#### Modified Rules
+
+*   The Java rules {% rule "java/multithreading/UnsynchronizedStaticFormatter" %} and
+    {% rule "java/multithreading/UnsynchronizedStaticDateFormatter" %} (`java-multithreading`)
+    now prefer synchronized blocks by default. They will raise a violation, if the synchronization is implemented
+    on the method level. To allow the old behavior, the new property `allowMethodLevelSynchronization` can
+    be enabled.
+
