+            Fixes a security issue in <tt>_.template</tt> that could enable a

+            affects all versions of Underscore between 1.3.2 and 1.12.0,
+            inclusive, as well as preview releases 1.13.0-0 and 1.13.0-1. The
+            fix in this release is also included in the parallel preview
+            release 1.13.0-2.

+          <li>
+            Restores an optimization in <tt>_.debounce</tt> that was
