+   Refer to issue #15573 for detailed information.
+
+ - A cross site scripting (XSS) vulnerability allowed execution of arbitrary

+
+ - In some cases, the 'Close' button would be available to unauthorized users,

+   Refer to issue #15453 for detailed information.
+
+This release also includes several bug fixes and enhancements to the tracker
