python3: upgrade 3.8.7 -> 3.8.8
Release Date: Feb. 19, 2021 Note: The release you're looking at is Python 3.8.8, a bugfix release for the legacy 3.8 series. Python 3.9 is now the latest feature release series of Python 3. Notable changes in Python 3.8.8 Earlier Python versions allowed using both ; and & as query parameter separators in urllib.parse.parse_qs() and urllib.parse.parse_qsl(). Due to security concerns, and to conform with newer W3C recommendations, this has been changed to allow only a single separator key, with & as the default. This change also affects cgi.parse() and cgi.parse_multipart() as they use the affected functions internally. For more details, please see their respective documentation. (Contributed by Adam Goldschmidt, Senthil Kumaran and Ken Jin in bpo-42967.)
