Thank you Benjamin Peterson.\n\nUpdate to 3.1.4 (boo#1168280, CVE-2020-6817):\n\n* ``bleach.clean`` behavior parsing style attributes could result in a\n  regular expression denial of service (ReDoS).\n  Calls to ``bleach.clean`` with an allowed tag with an allowed\n  ``style`` attribute were vulnerable to ReDoS. For example,\n  ``bleach.clean(..., attributes={'a': ['style']})``.\n* Style attributes with dashes, or single or double quoted values are\n  cleaned instead of passed through.\n\nupdate to 3.1.3 (boo#1167379, CVE-2020-6816):\n\n* Add relative link to code of conduct. (#442)\n* Drop deprecated 'setup.py test' support. (#507)\n* Fix typo: curren -> current in tests/test_clean.py (#504)\n* Test on PyPy 7\n* Drop test support for end of life Python 3.4\n* ``bleach.clean`` behavior parsing embedded MathML and SVG content\n  with RCDATA tags did not match browser behavior and could result in\n  a mutation XSS.\n  Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or\n  ``svg`` tags and one or more of the RCDATA tags ``script``,\n  ``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or\n  ``xmp`` in the allowed tags whitelist were vulnerable to a mutation\n  XSS.\n","title":"Description
