This isn't an option in 4.2.1 (and it is mentioned in the changelog too)

but WebUI still has "Listen on IPv6 address" option...

but seems to be it is unused, because regardless of its value (it shown as false, but I had it true in config before upgrade from 4.1.7) qBittorrent listens IPv6 addresses too:

nick@animesrv:~$ sudo netstat -tulnp | grep qbittorrent
tcp        0      0 0.0.0.0:43649           0.0.0.0:*               LISTEN      772/qbittorrent-nox 
tcp6       0      0 :::43649                :::*                    LISTEN      772/qbittorrent-nox 
tcp6       0      0 :::8080                 :::*                    LISTEN      772/qbittorrent-nox 
udp        0      0 0.0.0.0:43649           0.0.0.0:*                           772/qbittorrent-nox 
udp6       0      0 :::43649                :::*                                772/qbittorrent-nox 
nick@animesrv:~$ 

config still has it set to true (expected, I didn't change anything, and nothing can remove unused key from config):

root@animesrv:/home/nick# cat /var/lib/qbittorrent/.config/qBittorrent/qBittorrent.conf | grep -i ipv6
Connection\InterfaceListenIPv6=true
root@animesrv:/home/nick# 

qBittorrent 4.2.1, libtorrent 1.1.13 (from official Debian repo), other libs are also from Debian repo. system running Debian unstable.

@beckball didn't mention that he uses the WebUI. The changelog is on our website. Aka here: https://www.qbittorrent.org/news.php

@Kolcha I forgot to remove the UI element. I doesn't do anything nor does it read the value. You can get same behavior is you choose All IPv6 addresses from the drop-down menu of optional addresses.

@Kolcha I created a new wiki section for this: https://github.com/qbittorrent/qBittorrent/wiki/Explanation-of-Options-in-qBittorrent#Deprecated_options

The only way to remove the option from the config is manually (with qBittorrent closed).
