Notable changes in Python 3.8.12
================================
Starting with Python 3.8.12 the :mod:`ipaddress` module no longer accepts
any leading zeros in IPv4 address strings. Leading zeros are ambiguous and
interpreted as octal notation by some libraries. For example the legacy
function :func:`socket.inet_aton` treats leading zeros as octal notation.
glibc implementation of modern :func:`~socket.inet_pton` does not accept
any leading zeros.
