3.8.1 (2021-11-14)

Bugfixes

- Fix the error in handling the return value of `getaddrinfo`.

`getaddrinfo` will return an `(int, bytes)` tuple, if CPython could not handle the address family.

It will cause a index out of range error in aiohttp. For example, if user compile CPython with

`--disable-ipv6` option but his system enable the ipv6.
