We upgraded our conserver-server from 8.2.1 to 8.2.4 using the Debian packages and found that previously permitted clients were now refused access:
$ console myhost
10.2.3.4: access from your host refused
I found that the important difference between these two wasn't the source itself, but rather that Debian enabled --with-ipv6 for 8.2.4. Rebuilding 8.2.4 w/o --with-ipv6 restored the previous behavior, allowing clients the impacted clients to connect once again.
Our access block looks like this (with specific IPs/subnets modified for obfuscation):
