 ### API Changes
 
+  [Fixed issue 169 Add crumbFlag to renameJob][issue-169]
+
+  Added supplemental `renameJob` method which supports crumbFlag. Furthermore
+  added `renameJob` which supports folder with and without `crumbFlag`.
+  So we now have the following methods to rename jobs:
+
+```java
+public class JenkinsServer {
+  public void renameJob(String oldJobName, String newJobName) throws IOException;
+  public void renameJob(String oldJobName, String newJobName, Boolean crumbFlag) throws IOException;
+  public void renameJob(FolderJob folder, String oldJobName, String newJobName) throws IOException;
+  public void renameJob(FolderJob folder, String oldJobName, String newJobName, Boolean crumbFlag) throws IOException;
+}
+```
