| Doc Text: |
The Erlang port mapper daemon (epmd) can now listen on IPv6 addresses. In addition, clients can now register and query epmd over IPv6. This, in turn, now allows Erlang clustering to work in an IPv6-only environment. Previously, epmd could only bind and listen on IPv4 addresses, thereby preventing the formation of Erlang clusters in IPv6-only environments.c
