pycos version 4.7.2 has been released. In this version
Changed default value of ipv4_udp_multicast in py3 branch (for Python 3) to be False as documented (this was incorrectly True in version 4.7.1).
Changed multicast group address for IPv6 to a distinct form (from a generic simple form) so pycos doesn't interfere with any other devices that use generic multicast address.
