Release notes for 3.5 should mention Ice.IPv6

IPv6 is now enabled by default. The release notes mention that IPv6 behavior can be controlled by using Ice.PreferIPv6Address (New Features in Ice 3.5 - Ice 3.5 - ZeroC).

This is mostly relevant for client behavior, server side applications will fail to start if there is no IPv6 address available, error Protocol not supported. This is common in virtual environments, in these cases setting Ice.IPv6=0 will fix the problem.

It might also be worth noting this in Upgrading your Application from Ice 3.4 - Ice 3.5 - ZeroC as well.

    Thanks for the suggestion, I've added a note to the Upgrading page.
