========================== 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`).
