Django 1.8.14 release notes
===========================
*Under development*
*July 18, 2016*
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``.
