2020.11.20 Notice on disabling qbittorrent 4.x version

Recently, we discovered that the 4x.x series version of the qbittorrent client has serious data reporting errors.

This problem has caused serious user data statistics errors. In order to protect the rights and interests of users, LeagueHD will disable the qb client 4.xx version at 24:00 next Saturday (that is, 2020.11.28). Please adjust and replace it as soon as possible. For the client, downgrade qb to a version below 4.0 or use other clients. It is recommended to use clients such as utorrent and transmission.
