Django 2.1.6 release notes
==========================

*February 11, 2019*

Django 2.1.6 fixes a security issue and a bug in 2.1.5.

CVE-2019-6975: Memory exhaustion in ``django.utils.numberformat.format()``
--------------------------------------------------------------------------

If ``django.utils.numberformat.format()`` -- used by ``contrib.admin`` as well
as the ``floatformat``, ``filesizeformat``, and ``intcomma`` templates filters
-- received a ``Decimal`` with a large number of digits or a large exponent, it
could lead to significant memory usage due to a call to ``'{:f}'.format()``.

To avoid this, decimals with more than 200 digits are now formatted using
scientific notation.

Bugfixes
========

* Made the ``obj`` argument of ``InlineModelAdmin.has_add_permission()``
  optional to restore backwards compatibility with third-party code that
  doesn't provide it (:ticket:`30097`).
