Like similar previous issues #790 or #610, this is not a bug actually.

Django 4.2 needs mysqlclient 1.4.3 as minimum suppored version. Current PyMySQL has 1.4.0 as doctored version_info for MySQLdb compatibility.

Is it possible for MySQLdb version to be bumped up? If so, it will be very helpful for me. Thanks.
