+Notable changes in Python 3.8.12 |
|
2252 |
+================================ |
|
2253 |
+ |
|
2254 |
+Starting with Python 3.8.12 the :mod:`ipaddress` module no longer accepts |
|
2255 |
+any leading zeros in IPv4 address strings. Leading zeros are ambiguous and |
|
2256 |
+interpreted as octal notation by some libraries. For example the legacy |
|
2257 |
+function :func:`socket.inet_aton` treats leading zeros as octal notation. |
|
2258 |
+glibc implementation of modern :func:`~socket.inet_pton` does not accept |
|
2259 |
+any leading zeros. |
