Furthermore, "In 0.2.8, clients assume that the IPv6 DirPort is the same as the IPv4 DirPort" already. If that's still true, might as well leave the v4 port advertised, and if a v6 client comes along it will try the (non-advertised) v6 port anyway.

In 0.2.8.3-aplha, "clients, onion services, and bridge relays always use an encrypted begindir connection for directory requests".
Encrypted beginner connections are made over the ORPort.
This means that in 0.2.8 clients no longer use any DirPort, and relays only use the IPv4 DirPort.
IPv6 clients and bridge clients use the IPv6 ORPort.

In 0.2.7 and before, clients and relays only use the IPv4 DirPort.
IPv6 bridge clients use the IPv6 ORPort.
