 Django 1.8.14 release notes
 ===========================

-Django 1.8.14 fixes several bugs in 1.8.13.
+Django 1.8.14 fixes a security issue and a bug in 1.8.13.
+
+XSS in admin's add/change related popup
+=======================================
+
+Unsafe usage of JavaScript's ``Element.innerHTML`` could result in XSS in the
+admin's add/change related popup. ``Element.textContent`` is now used to
+prevent execution of the data.
+
+The debug view also used ``innerHTML``. Although a security issue wasn't
+identified there, out of an abundance of caution it's also updated to use
+``textContent``.
